53-2021 CHARACTERIZE ROOT MICROBIAL COMMUNITIES WITH ANTI-FUNGAL ACTIVITIES IN SOYBEAN ANNUAL REPORT
Plant roots associate with a microbial community that is distinct from the microbes present in surrounding soil. The microbes colonize the rhizosphere (immediately surrounding the plant's roots) and the superficial root tissues (endophytic compartment). The root microbiota comprises a wide diversity of microorganisms, and it can benefit plant health or have detrimental effects; shifting this balance towards beneficial plant-microbiota interactions is of high agronomic interest. Microbes may provide the plant with nutrients that accelerate plant growth and development, suppress soil pathogens, or help plants withstand environmental stress. The advantages of exploiting microbiota are evident and include consumers' and farmers' safety and sustainable practices that preserve the environment and protect biodiversity.
15-2021 Determining Management-Related Factors that Impact the Severity and Incidence of Soybean Taproot Decline Final Report
Soybean taproot decline (TRD), an important soilborne root disease, is shaping up to become one of the major diseases facing soybean producers in Mississippi, and beyond. TRD has been increasing in Mississippi since the first reports more than 12 years ago but yield losses and economic damages have yet to be accurately quantified. The causal agent of TRD is identified recently as Xylaria necrophora, and vast majority of the Xylaria species are saprophytic fungi (decomposers), which is consistent with anecdotal observations linking TRD and prior soybean crop, or other residues and reduced tillage systems.
Safeguarding Mississippi Soybean Production From Interactive Heat and Drought Stress-Induced Yield and Quality Issues 43-2021 Annual Report
For every 0.8°C increase above 26.7°C (80oF), the current mean temperature of the southern United States, soybean yields are expected to decline by 2.4%. Under field conditions, soybean exposed to high temperature (97°F) and drought stress suppresses the plant health, quality, and nutritional value beans by reducing leaf photosynthetic rate, stomatal conductance, and increased canopy temperatures during R1 to R6. To date, soybean breeding programs are successful in increasing yield potential in a favorable environment. However, progress in breeding for interactive stress tolerance has not received similar attention. Here, we aim to quantify soybean plant health, yield, and seed compositional changes in response to heat and drought stress conditions
