Soybean (Glycine max) morphogenesis and flowering time are accurately regulated by photoperiod, which determine the yield potential limit soybean cultivars to a narrow latitudinal range. The E3 E4 genes, encode phytochrome A photoreceptors in soybean, promote expression of legume-specific repressor E1 delay floral transition under long-day (LD) conditions. However, underlying molecular mechanism remains unclear. Here, we show that diurnal pattern GmEID1 is opposite targeted mutations gene...
Abstract Shading in combination with extended photoperiods can cause exaggerated stem elongation (ESE) soybean, leading to lodging and reduced yields when planted at high-density high-latitude regions. However, the genetic basis of plant height adaptation these regions remains unclear. Here, through a genome-wide association study, we identify regulating gene on chromosome 13 ( PH13 ) encoding WD40 protein three main haplotypes natural populations. We find that an insertion Ty1/Copia -like...
Major cereal crops have benefitted from Green Revolution traits such as shorter and more compact plants that permit high-density planting, but soybean has remained relatively overlooked. To balance ideal yield with plant height under dense shortening of internodes without reducing the number nodes pods is desired. Here, we characterized a short-internode mutant, reduced internode 1 (rin1). Partial loss SUPPRESSOR OF PHYA 105 3a (SPA3a) underlies rin1. RIN1 physically interacts two homologs...
Plant height influences plant architecture, lodging resistance, and yield performance. It is modulated by gibberellic acid (GA) metabolism signaling. DELLA proteins, acting as central repressors of GA signaling, integrate various environmental hormonal signals to regulate growth development in Arabidopsis. We examined the role two GmRGAa GmRGAb, soybean control. Knockout these proteins led longer internodes increased height, primarily increasing cell elongation. GmRGAs functioned under...
