4. Food, feed, nutrition and industrial uses
5. Business and legal issues
WSRC XII 2027 aims to attract a wide range of participants across the soybean value chain—from research and production to commercialization and industrial processing—including agronomists, breeders, geneticists, molecular biologists, plant nutritionists, physiologists, weed scientists, plant pathologists, entomologists, industry representatives, academics, economists, and policymakers.
We encourage you to share your research and findings with the global soybean community.

Nowadays the development of sustainable and environmentally-friendly strategies using soil beneficial microbes as plant growth-promoting rhizobacteria (PGPR) and biocontrol agents (BCA) is gaining great consideration to reduce the use of agrochemicals in crops production. Considering the above, 78 actinobacteria from the genus Streptomyces were isolated from the rhizosphere and endosphere of soybean plants from the Argentinean core production zone. Among these, two strains (N2A and N9) were selected based on their in vitro compatibility with Bradyrhizobium japonicum (B), their ability to produce phytohormones, siderophores, phosphate solubilization and their antagonism to fungal pathogens. These strains were evaluated during 2021/22 growing season to analyze their effect as PGPR under field conditions. The treatments were N2A+B, N9+B, fungicide (F+B) and control (B). The assay was performed following a completely randomized block design at the experimental field (Agronomy Faculty-Zavalla, Santa Fe, Argentina). As results, Streptomyces spp. treatments significantly promoted seedlings emergence compared to B and F+B. At harvest, both Streptomyces strains significantly increased seed yield (g/m2) compare to the conventional agronomical practice (F+B), and N2A+B also showed higher yields than B (P<0.05). These increases were related to rises in seed number/m2 and pod number in the main stem (P<0.10). Finally, a significant increase in vigor and health status was observed for seeds obtained from plants of both Streptomyces treatments in comparison to seeds obtained from B and F+B treatments, while no differences were observed in protein and lipids content. Altogether, we demonstrated that the seed treatment with Streptomyces spp. promotes growth and development of soybean crop, possibly due to a better nutritional and health status of the plants, increasing yield and the physiological and sanitary quality of the seeds in field conditions. Thus, we propose the replacement or complementation of traditional agrochemicals with more efficient and environmentally friendly technologies based on these soil bacteria.

Soybean stem canker: molecular markers assisted stacking of Rdm/Rdc genes

Soybean [Glycine max (L.) Merr.] crop is seriously affected worldwide by stem canker (SSC) disease, caused by Diaporthe aspalathi (ex D. phaseolorum var. meridionalis) (SSC‐Da) and D. caulivora (SSC‐Dc). Both Diaporthe spp. coexist in the core productive zone of Argentina and can infect stem and seed tissues. Furthermore, with the increased seed movement between northern and southern states in US and between US and South America, the development of resistant germplasm is determinant to reduce the impact of these pathogens on crop production and seed quality. Thus, the objectives of this work were (i) to analyze the resistance sources to SSC‐Da (Rdm genes) and SSC‐Dc (Rdc gene) present in the varieties currently sown in Argentina, as well as in germplasm from the University of Arkansas (US), by genotyping with molecular markers (MM) linked to Rdm3, Rdm4, Rdm5 and Rdc1 genes previously identified by our group; (ii) to stack Rdm3, Rdm4‐5 and Rdc1 genes conferring resistance to SSC‐Da and SSC‐Dc, respectively, in order to confer a more durable and broader resistance to both causal agents. The results indicate that 55% of the genotypes have the Rdm4 gene incorporated, less than 5% have the Rdm3 gene, 21% have other alleles and the remaining do not present resistance alleles. Meanwhile, none of the tested genotypes have the MM linked to Rdc1 gene incorporated. These results suggest that most of currently cultivated soybean germplasm has the same resistance source to SSC‐Da and does not present resistance to SSC‐Dc. Finally, based on these results and assisted by the linked MM, the stacking of Rdm3, Rdm4 and Rdc1 genes in elite germplasm with good agronomic performance is in progress, to be used as donors in breeding programs aimed to incorporate a broader and more durable resistance to SSC.
