As a leading oilseed crop that supplies plant oil and protein for daily human life, increasing yield improving nutritional quality (high or protein) are the top two fundamental goals of soybean breeding. Seed size is one most critical factors determining yield. size, contents complex quantitative traits governed by genetic environmental during seed development. The composition quantity storage reserves directly affect size. In general, make up almost 60% total seed. Therefore, soybean's oil, content highly correlated agronomical traits. Increasing helps increase probably improves quality. Similarly, rising will likely Due to importance these three in breeding, extensive studies have been conducted on their underlying trait locus (QTLs) genes dissection molecular regulatory pathways.

Abstract Leaf senescence is a crucial trait that has significant impact on crop quality and yield. Previous studies have demonstrated light key factor in modulating the process. However, precise mechanism by which plants sense control remains largely unknown, particularly species. In this study, we reveal reduction blue under shading conditions can efficiently induce leaf soybean. The receptors GmCRY1s rather than GmCRY2s, primarily regulate response to signals. Our results show interact with DELLA proteins light-activated conditions, stabilizing them consequently suppressing transcription of GmWRKY100 delay senescence. Conversely, LBL reduces interaction between proteins, leading their degradation premature leaves. findings suggest GmCRY1s-GmDELLAs-GmWRKY100 regulatory cascade involved mediating LBL-induced soybean, providing insight into how signals Additionally, generate knockout soybeans delayed improved yield natural field indicating potential applications enhancing soybean production manipulating trait.

Published: Jan. 6, 2025

While the genetic regulation of nodule formation has been well explored, molecular mechanisms by which abiotic stresses, such as salt stress, impede remain largely elusive. Here, we identify four APETALA2/Ethylene Responsive Factor (AP2/ERF) transcription factors, GmERF13s, that are induced stress and play key roles in salt-repressed nodulation. Loss GmERF13 function increases density, while its overexpression suppresses Moreover, stress-inhibited is greatly attenuated loss-of-function mutants, whereas it becomes more pronounced when overexpressed. Furthermore, GmERF13s can interact with Lateral Organ Boundaries Domain 16 (GmLBD16a), attenuates GmLBD16a's binding capacity on Expansin17c (GmEXP17c) promoter. Additionally, salt-induced expression relies abscisic acid signaling, direct promotion facilitated GmABI5, illustrating their involvement enhancing expression. Collectively, our study reveals a mechanism impedes nodulation through GmERF13-GmLBD16a-GmEXP17 module soybean.
