Download AbstractAbstract
Intercropping is an agricultural practice involving the simultaneous cultivation of multiple crop species on the same land area. This approach is gaining increasing recognition for its potential to enhance productivity in both food and forage systems, while also delivering important environmental benefits. By strategically combining high-yielding crops with less profitable or cover crops, intercropping creates mutual synergies that improve overall system performance. It is particularly valuable in optimizing crop yields, reducing dependency on synthetic chemical inputs, and improving water-use efficiency—especially in arid and semi-arid regions. Moreover, intercropping contributes to restoring biodiversity that has been degraded by monoculture practices and agricultural intensification.
Paulownia, a fast-growing tree species, is particularly well-suited to tree-based intercropping systems (TBI) due to its high biomass production and exceptional capacity for carbon dioxide absorption. Its inclusion in agroforestry systems offers promising prospects for reforestation and the development of more sustainable agroecosystems. Buckwheat, on the other hand, is an excellent choice for cultivation between trees in agroforestry systems because it can improve soil quality and is a highly nectar plant
The aim of the present study was to assess biodiversity at three ecological levels—arthropods, weeds, and microorganisms—within a Paulownia–buckwheat intercropping system established on arable land in southwestern Poland. The results demonstrate that intercropping these two melliferous species enhances soil biodiversity and ecological functioning. Specifically, this cultivation model fosters beneficial changes in soil microbial communities and mesofauna structure, contributing to improved soil quality under local conditions.
Importantly, the intercropping of buckwheat with paulownia did not result in any deterioration of the biometric traits or yield of buckwheat. On the contrary, the system supports sustainable production while simultaneously enhancing ecological value. Given these outcomes, Paulownia–buckwheat intercropping appears to be a promising approach for integrated biodiversity conservation and agricultural sustainability in temperate European climates.

Country : Ethiopia
Download AbstractAbstract
Cylicomorpha solmsii (Urb.) Urb. (Caricaceae) is a wild species that could serve as an essential genetic resource for improving the quality and quantity of production in its close domesticated relative, Carica papaya. Unfortunately, research on this species remains limited. Our work aimed to initiate the process of conserving, restoring, and enhancing this neglected, underexploited, and endangered genetic resource in Cameroon. Our investigations concentrated on the ecological, anatomical, physiological, and genomic aspects of C. solmsii. Our results illuminated the phenology of the fruits, updated the morphological description of the species, and defined certain conditions for seed germination. Additionally, we assembled a female diploid reference genome and a male genome of C. solmsii de novo using HiFi PacBio long reads. Consequently, we identified the sex chromosome, the non-recombining region, and the sex-determining region. Two candidate sex-determining genes were identified, featuring protein domains that suggest carpel suppression and stamen promotion. This study offers valuable insights for the conservation and restoration of C. solmsii, providing essential genomic and ecological data for its utilization in Carica papaya breeding programs.

Title : Leaf HydrogenPeroxide Concentration as an Indicator of Colonizable Areasin Riparian Zones in Response to Soil Moisture Levels
Name : Takashi Asaeda
University : Saitama University, Sakura Saitama
Country : Japan
Download AbstractAbstract
The identification of colonizable species is a critical component of riparian zone management. Plant species require specific environmental conditions to successfully establish themselves in a given area. In riparian zones, variations in soil moisture create a distinct gradient that influences vegetation establishment at species-specific elevations. The concentration of hydrogen peroxide (H₂O₂) in leaves may serve as a reliable indicator of suitable conditions for colonization.
To investigate this hypothesis, leaf samples from various riparian plant species were collected from multiple riverine environments across different seasons, specifically on cloudless days with moderate temperatures. In addition to measuring H₂O₂ concentration in the leaves, environmental factors such as soil moisture, solar radiation, and temperature were recorded. The data were then analyzed to assess the relationship between H₂O₂ levels, soil moisture, and other influencing factors.
The results revealed that H₂O₂ concentration exhibited species-specific trends in response to soil moisture, regardless of seasonal variations. Generally, H₂O₂ levels were highest under low soil moisture conditions but gradually declined as soil moisture increased. In species capable of colonizing
inundated zones, such as Phragmites australis, H₂O₂ levels continuously decreased and remained relatively constant. However, in species typically found in elevated zones, H₂O₂ concentration increased sharply under near-saturated soil moisture conditions.
H₂O₂ is primarily generated by surplus electrons during photosynthesis. It forms when there is an imbalance between the electrons produced by absorbed solar energy at Photosystem II (PSII) and those consumed during carbohydrate synthesis in the Calvin cycle. Additionally, H₂O₂ is produced during respiration when carbohydrates are broken down.
At low soil moisture levels, stomatal closure restricts carbon dioxide (CO₂) intake, leading to excess electron accumulation and increased H₂O₂ production. As soil moisture levels rise, stomata open, allowing greater CO₂ uptake, which facilitates carbohydrate synthesis and reduces H₂O₂ concentration. Species adapted to inundated zones maintain an efficient oxygen transport system, enabling them to balance electron generation and consumption, thereby keeping H₂O₂ levels consistently low, even in near-saturated conditions. In contrast, species that typically colonize elevated zones lack tolerance for anoxic conditions. Consequently, although electrons are consumed during photosynthesis, reduced carbohydrate decomposition results in electron accumulation and increased H₂O₂ generation.
These findings suggest that leaf H₂O₂ concentration can serve as an integrated indicator of drought or
flood stress, providing valuable insights into the environmental feasibility of plant colonization.

Name : Olga Elina
University : Institute for the History of Science and Technology, Russian Academy of Sciences, Moscow
Country : Russia
Download AbstractAbstract
The contemporary agenda of historical science reveals a growing interest in the issue of women in agriculture and plant research. This interest coincides with and perhaps is caused by today’s growing presence of women in ensuring global food security, especially in the realm of developing countries. The history of women’s entry into agriculture and plant research is generally well documented and includes both the study of national characteristics of higher education, industries, and professions related to agriculture and horticulture and individual cases of women’s impute to plant research. In this presentation, I will contribute to comparative international and national historical research by uncovering the still little-known case of Russia. My research focuses on motivations and obstacles for women’s coming into agriculture and horticulture in Russia at the beginning of the 20th century. Despite the prevailing model of higher education in the Russian Empire being a predominantly state institution, I argue the impact of the scientific societies on actualizing the discourse of female education and launching a chain of non-governmental schools for women. My primary target is to identify the key actors that took part in transforming of traditional understanding of women’s “subordinate” role in agriculture, and the mechanisms through which it was accomplished. I will particularly explore yearly educational institutions for women in terms of teaching ideology, curricula, and practical training courses. Finally, I will trace the professional trajectories of the first women agronomists and plant scientists, including their career choice motivations, political positions, scientific accomplishments, and personal lives.

Title : Potential Pesticidal Activities in Lamiaceae herbs: A Linkage Through Phytochemical Analysis
Name : Om Prakash
University : G.B. pant University of Agriculture and Technology
Country : India
Download AbstractAbstract
There is a growing demand of alternatives in pest management for sustainable agriculture as a result of awareness about the environmental and health risks associated with synthetic pesticides. Biopesticides, derived from plants, microbes, and minerals, have emerged as a promising solution to address and mitigate these concerns. The natural pesticides are eco-friendly and leverage the natural properties of living organisms or their byproducts to manage pests. Unlike synthetic chemical pesticides, biopesticides have minimal risks to non-target organisms, including humans, beneficial insects, and the environment. They posses several advantages, viz; high specificity, biodegradability, low persistence, and reduced development of resistance in target pests. The biopesticides can be integrated with other pest management strategies, such as cultural practices and biological control, to establish comprehensive and sustainable pest management programs. The potential applications of biopesticidal span across various sectors of agriculture, like crop protection, horticulture, forestry, and stored product management. The biopesticides have efficacy against a wide range of pests, including insects, mites, nematodes, plant pathogens and weeds, particularly important in organic farming systems, where their use aligns with the principles of ecological sustainability and reduced chemical inputs. The compatibility of biopesticides with integrated pest management (IPM) approach also allows for effective pest control. The unique characteristics, like high specificity, low toxicity, and eco-friendly profiles, make them valuable tools in modern pest management strategies. As research and development in this field continue to advance, biopesticides hold the potential to revolutionize agriculture through promoting sustainable practices, safeguarding human health, and conserving biodiversity. Further exploration, innovation, and adoption of biopesticides are crucial to foster a resilient and sustainable future for pest management. In view of these facts and in continuation to our research programme we are working on the pesticidal activities of essential oils/extracts/pure compounds against root knot nematodes like Meloidogyne incognita insects like Spilosoma obliqua, Lipaphis erysimi, etc. In present deliberation emphasis will be given to taxonomic identification pescticidal applications, chemical diversity, of some important Lamiaceae herbs growing in Uttarakhand Himalaya of India.

Title : Unravelling the mechanisms of salt stress tolerance in mycorrhizal plants
Name : Bhoopander Giri
University : Swami Shraddhanand College (University of Delhi)
Country : India
Download AbstractAbstract
Due to extensive use of chemical fertilizers and pesticides, low rainfall, increased evaporation, weathering and suboptimal irrigation practices, the accumulation of soluble salts in agricultural fields is increasing gradually, making the soil saline. Increasing soil salinity drastically influences growth and productivity of plants. Mycorrhizal fungi (MF) form symbiotic relationships and play a crucial role in enhancing plant growth by promoting nutrient uptake under saline conditions. They help their partner plants in mitigating injurious effects of soluble salts, prevalent in a saline habitat. MF alter morphological, physiological, biochemical attributes of plants and also help in upholding cell ultra structures remain intact under saline conditions. In our studies, the mycorrhiza-inoculated plants exhibited increased photosynthetic and transpiration rates, internal CO2 and stomatal conductance. They increased the accumulation of glycine betaine, total sugars, trehalose, proline, putrescine, spermidine, carotenoids, proteins and α-tocopherols and decreased lipid peroxidation and lipoxygenase activity, thus validating the increased stress tolerance in mycorrhizal plants. Besides, MF also helped the host plant to overcome salinity-induced nutrient deficiency along with reduced Na+ accumulation, which is an indicative of enhanced nutrient status, and reduced damage to cell structures, particularly plasma membrane and chloroplasts. The ultrastructural analysis of chloroplast revealed preserved thylakoids and grana in MF-inoculated plants in contrast to uninoculated plants under saline conditions. The cell membrane of MF-inoculated plants displayed reduced detachment from the cell wall, representing improved membrane integrity. Our results emphasize the significant roles of MF in mitigating salinity stress and the practical application of MF to improve plant’s tolerance to salt stress and also to promote sustainable agriculture in salt affected areas.

Country : UAE
Download AbstractAbstract
Plant growth-promoting rhizobacteria (PGPRs) can mitigate the detrimental impacts of salt stress on plants. The current research reports the isolation of PGPRs from high-saline mangrove environments. These isolates exhibited ACC deaminase action to alleviate the stress ethylene, along with additional plant growth-accelerating characteristics such as phosphate dissolution and indole-3-acetic acid (IAA) biosynthesis. The molecular profiling of PGPRs revealed that the isolates Bacillus subtilis (isolate B1) and Bacillus siamensis (isolate B3) could alleviate salt stress-induced injury and create tolerance in the tomato plants. Inoculation of isolates B1 and B3 protected the tomato plants in the greenhouse, from the detrimental effects of NaCl and significantly boosted the shoot length, shoot dry weight (DW), shoot fresh weight (FW), root DW, root FW, and flowers count per tomato plant cultivated in saline conditions.
Further, chlorophyll-a fluorescence studies displayed that the plants inoculated with isolates B1 and B3 demonstrated higher efficiency of photosystem II (PSII) than control plants, in NaCl-triggered salinity stress conditions.
Additionally, leaf spectral reflectance showed improved stomatal conductance-associated spectral signatures in tomato plants inoculated with B1 and B3 isolates. Overall, the study findings suggested that isolates B1 and B3 could be utilized to develop biofertilizers to improve the production of tomato grown under saline conditions.

Title : Tropical Tidal Wetland Vegetation Mosaics: Relationships with Micro-Topography and Tidal Hydroperiod
Name : Cecile Vulliet
University : College of Science and Engineering, James Cook University
Country : Australia
Download AbstractAbstract
Saltmarshes are critical ecosystems that play key roles in biodiversity conservation and carbon sequestration, providing multiple ecological and economic values essential for sustainable development. Yet, saltmarshes are threatened by human activities and sea-level rise (SLR). Long-term restoration and management strategies are necessary but often hindered by an insufficient understanding of the past, present, and future processes that influence tidal wetland functionality and change. Since understanding vegetation distribution in relation to elevation and tidal hydroperiod generally forms the basis of tidal wetland restoration strategies, this research investigated the relationships between micro-topography, tidal hydroperiod, and the distribution of saltmarshes, mangroves, and unvegetated flats in a tropical estuary situated within a Great Barrier Reef Catchment in North Queensland, Australia. We used a combination of high-resolution unattended-aerial-vehicle (UAV)- derived digital elevation model (DEM) and land cover coupled with 2D hydrodynamic modelling to investigate these aspects. We found overlapping distribution across elevation, highlighting that zonation was more complex than strict zonation patterns generally recognised in restoration and legislation. In addition, although each type of tidal wetland cover had distinct mean hydroperiods, and elevation and hydroperiods were strongly correlated, elevation explained only 15% of the variability in tidal wetland cover distribution. This finding implies that additional factors likely play a role in shaping tidal wetland cover zonation patterns in tropical tidal wetlands. These results hold significance as they underscore the need to exercise caution when applying oversimplistic explanations for the causality of tidal wetlands. The suitability of applying simplistic rules in management and restoration is likely to be context-dependent, as demonstrated in our study site. Contextual variabiltiy in environmental and biological factors may lead to different distribution patterns of tidal wetland components, and hence varying restoration and management success. This research also explored the potential effects of sea-level rise (SLR) on the tidal hydroperiods and connectivity of the study site. Our results showed that the inundation experienced by each tidal wetland cover may increase importantly if vegetation does not keep up with SLR. This underlines the importance of acquiring detailed spatio-temporally resolved data to enable the development of robust long-term and adaptive saltmarsh management strategies. This research highlights the uncertainties and complexities in understanding the processes influencing tropical tidal wetland functionality. Recognising these complexities is paramount for effectively managing and restoring tidal wetland ecosystems and, hence, maintaining their critical ecological and economic values.

Country : Korea
Download AbstractAbstract
Due to the global warming, the growth and production of crops including radish is unstable, and the damage to the farmhouse is increasing. After heat shock treatment in 60 diverse radish varieties, the difference in heat shock resistance is investigated, and excellent high temperature resistant varieties and 3 high temperature sensitive varieties are selected. To identify specific genes involved in heat stress as upstream signaling components in high temperature resistant variety, gene expression of 76 receptor-like
cytoplasmic kinases (RLCKs) under high temperature (37°C, 2 hr) were analyzed and 3 RLCKs (Rs275520, Rs355490, Rs032070) were significantly increased at 37° C compared to normal temperature (23°C) in contrast of a Rs497590 gene expression slightly
decreased. Also, analyzed downstream components, which could be involved in heat stress resistance with RT-PCR. Rs032070 interacting proteins identified 8 proteins with Yeast Two Hybrid (Y2H) system and expression of 8 genes interacts with Rs032070 investigated under ) in heat-shock condition and all of gene expression is induced by heat-shock treatment. Interestingly, protein phosphatase 7 (PP7, Rs499360) gene expression increased in heat-tolerant varieties at 37°C treatment although difference of PP7 expression was not observed in heat stress-sensitive varieties. Using PP7 as bait, identified 4 different interacting proteins with Y2H and 2 genes, SCE1 and chlorophyll a-b binding protein 4 transcripts level increased significantly at 37°C. These results are helpful in understanding the mechanism in terms of climate warming including heat stress in radish.
Title : Sustainable Plant-Based Dietary Supply Chain Design to Reduce Malnutrition in Deprived Areas
Name : Shima Yekkehbash Heidari
University : Cardiff University
Country : UK
Download AbstractAbstract
Food and Agriculture Organization (FAO) of the United Nations has reported that malnutrition elimination and people’s eating habits have the immense potential to alter the world food demand in 2050. Hence, strategists should incorporate the mentioned elements to properly manage the food industry. This paper aims to present a comprehensive model for integrating strategic and tactical decisions to manage a forward environmentally-friendly perishable food supply chain (FSC). In this paper, a new mathematical model is presented in that incorporates location-allocation decisions with sourcing, transportation, and scheduling decisions. A four echelon supply chain to fulfil the nutrient demand of customers and their quality requirements of both fresh and processed products are addressed in this paper. The applicability of plant-based dietary patterns to reduce malnutrition through sustainable supply chain management is illustrated. Initially, a new bi-objective mixed-integer non-linear programming model is provided and intended to minimize both the total costs and the cumulative environmental impacts, including soil degradation, water use, CO2 emissions, and fuel consumption. The nutritional requirements of each customer zone, meat consumption avoidance, and regional development are included as the social aspect of sustainability. Next, a Ɛ-constraint approach is applied to obtain Pareto points. In the end, a real numerical example considering a reduced plant-based diet is analysed for further analysis and managerial insights.
Our proposed model can be employed by the government and non-profit organizations when the salient purpose is to ameliorate the irreparable effects of malnutrition. The model can provide the food sector managers with valuable insights into designing a greener, more responsive, and more profitable supply chain. The resultant managerial insights after solving the proposed model for a real case study are 1) The importance of agricultural production to building a sustainable food system cannot be overemphasized; 2) For managers to alleviate malnutrition while minimizing costs and environmental burdens, the product’s nutrient profile is of a higher priority regardless of its deteriorating speed; 3) Improving the nutritional value of processed products seems to be more effective than establishment and manufacturing costs to ensure the selection of processed products in diets; and 4) Dietary diversity can be achieved by incurring a 14% increase in total costs.
