“…Transgenic plants overexpressing GmBZL2 P216L or GmBZL3 P219L ( AtBZR1 -like gene) could partially rescue the defects of bri1-5 Arabidopsis mutants, which suggests that GmBZL functions are conserved between soybean and its homolog in Arabidopsis 19,20 . Similarly, soybean cultivars with relatively large pods are inclined to have a relatively high GmBZR1 expression level in the pods 21 . Furthermore, the growth defects of the BR-insensitive mutant bri1-5 can be complemented by overexpressing GmBRI1 22,23 .…”

Soybean is a widely grown grain legume and one of the most important economic crop species. Brassinosteroids play a crucial role in plant vegetative growth and reproductive development. However, it remains unclear how BRs regulate the developmental processes in soybean, and the molecular mechanism underlying soybean early development is largely unexplored. In this study, we first characterized how soybean early vegetative growth was specifically regulated by the BR biosynthesis inhibitor propiconazole; this characterization included shortened root and shoot lengths, reduced leaf area, and decreased chlorophyll content. In addition, the growth inhibition induced by Pcz could be rescued by exogenous brassinolide application. The RNA-seq technique was employed to investigate the BR regulatory networks during soybean early vegetative development. Identification and analysis of differentially expressed genes indicated that BRs orchestrate a wide range of cellular activities and biological processes in soybean under various BR concentrations. The regulatory networks between BRs and multiple hormones or stress-related pathways were investigated. The results provide a comprehensive view of the physiological functions of BRs and new insights into the molecular mechanisms at the transcriptional level of BR regulation of soybean early development.

“…Two additional relevant genes related to soybean pod growth have been reported, GmBRI1 and GmCYP45085A1,2 (Ariyoshi et al., 2016; Wang et al., 2014). These genes regulate the development of soybean pods by affecting brassinosteroids.…”

Seed size is an important factor affecting soybean (Glycine max) yield and quality, and the length and width of the pods are significantly related to the seed size. Soybean two‐seed pod is a stable pod‐setting trait. Based on soybean chromosome segment substitution line (CSSL), QTL‐seq method was used to locate the QTL of soybean two‐seed pod length (TSPL) and width (TSPW) and to mine the related genesA total of 3 QTLs for TSPL and 5 QTLs for TSPW were obtained. Among them, the positions of qTSPL‐B1‐1 and qTSPW‐B1‐1 overlapped, and this overlapping interval was used as the major QTL for soybean TSPL and TSPW. Haplotype analysis revealed that the haplotype variation of Glyma.11G051600 would cause the phenotypes of TSPL and TSPW to vary. RT‐pcr showed that the expression of Glyma.11G051600 was closely related to the development of soybean TSPL and TSPW. Therefore, Glyma.11G051600 was used as a common gene to regulate the growth and development of TSPL and TSPW. These results provide a basis for research on candidate genes and marker‐assisted selection (MAS) for soybean breeding.

“…3 Decreasing of soybean pod size by brasinosteroid biosynthesis inhibitor resulted in reduction of 100-seed weight. 4 These data suggest that seed weight could be controlled by restriction of pod growth. However, the mechanisms of pod growth have not yet been clarified even though 100-seed weight is one of the crucial yield components in legume.…”

Effects of light quality on pod elongation in soybean (Glycine max (L.) Merr.) and cowpea (Vigna unguiculata (L.) Walp.)Seiya Tanaka a , Nobuyuki Ario a , Andressa Camila Seiko Nakagawa a , Yuki Tomita a , Naoki Murayama a , Takatoshi Taniguchi ABSTRACTSoybean pods are located at the nodes, where they are in the shadow, whereas cowpea pods are located outside of the leaves and are exposed to sunlight. To compare the effects of light quality on pod growth in soybean and cowpea, we measured the length of pods treated with white, blue, red or far-red light. In both species, pods elongated faster during the dark period than during the light period in all light treatments except red light treatment in cowpea. Red light significantly suppressed pod elongation in soybean during the dark and light periods. On the other hand, the elongation of cowpea pods treated with red light markedly promoted during the light period. These results suggested that the difference in the pod set sites between soybean and cowpea might account for the difference in their red light responses for pod growth. IntroductionPods encapsulate the developing seeds and protect them from pests and pathogens. 1 Pod length and width are positively correlated with final seed size. 2 In soybean, cultured seeds continue to grow compared with seeds in pod, which suggests that soybean seed growth is physically suppressed by the pod wall. 3 Decreasing of soybean pod size by brasinosteroid biosynthesis inhibitor resulted in reduction of 100-seed weight. 4 These data suggest that seed weight could be controlled by restriction of pod growth. However, the mechanisms of pod growth have not yet been clarified even though 100-seed weight is one of the crucial yield components in legume.Light is an important environmental signal that regulates plant growth and development. Blue light (BL), red light (RL), and far red light (FRL), which are sunlight components, regulate plant growth. Plants perceive BL via the photoreceptors cryptochromes (CRY1 and CRY2) and phototropins (phot1 and phot2), and RL and FRL via phytochromes (phyA-phyE). 5-7 Arabidopsis hypocotyl elongation is induced in the dark and is inhibited by light. 8 BL and RL suppress Arabidopsis hypocotyl growth through the CRY1 and phyB photosensory pathways, respectively. 9,10 In soybean, RL increases plant height, 11 and BL suppresses stem elongation. 12 Soybean pods are located at the nodes and receive weakened sunlight due to shading, whereas cowpea pods are located outside of the leaves and receive sunlight directly (Fig. 1). However, the effects of light on pod growth of soybean and cowpea has never been studied so far. Therefore, we investigated the effects of light quality on pod growth in these species. Results and discussionTo investigate the effects of light on pod growth in soybean and cowpea, we treated the plants with WL or monochromatic light (BL, RL or FRL). The elongation rate of soybean and cowpea pods was higher during the dark period than during the light period in all light treatments (Fi...
