“…SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 ( SOC1 ) encodes a MIKC c -type MADS-box transcription factor which is involved in regulating the flowering time ( Lee and Lee, 2010 ). Loss of function of GmSOC1 in soybean exhibited delaying the flowering time and increased the PH under both short-day and long-day conditions ( Kou et al, 2022 ). There are two SOC1 homologs present in soybean ( SOC1a and SOC1b ).…”

“…There are two SOC1 homologs present in soybean ( SOC1a and SOC1b ). The GmSOC1a and GmSOC1b complex interacts with Dt2 to repress the transcription of Dt1 through binding to the Dt1 promoter, indicating the role of SOC1 in soybean stem growth habit ( Figure 1 ; Liu et al, 2016 ; Kou et al, 2022 ). Moreover, Phytochromes E3 and E4 promote PH and NN by inducing Dt1 transcription indirectly ( Figure 1 ; Xu et al, 2013 ).…”

Soybean is one of the most important legume crops that can provide the rich source of protein and oil for human beings and livestock. In the twenty-one century, the total production of soybean is seriously behind the needs of a growing world population. Cultivated soybean [Glycine max (L.) Merr.] was domesticated from wild soybean (G. soja Sieb. and Zucc.) with the significant morphology and organ size changes in China around 5,000 years ago, including twisted stems to erect stems, small seeds to large seeds. Then it was spread worldwide to become one of the most popular and important crops. The release of the reference soybean genome and omics data provides powerful tools for researchers and breeders to dissect the functional genes and apply the germplasm in their work. Here, we summarized the function genes related to yield traits and organ size in soybean, including stem growth habit, leaf size and shape, seed size and weight. In addition, we also summarized the selection of organ traits during soybean domestication. In the end, we also discussed the application of new technology including the gene editing on the basic research and breeding of soybean, and the challenges and research hotspots in the future.

“…Photoperiod directly affects E1 , E3 and E4 loci which in turn interact with E2 , E9 and J for regulating flowering and maturity response. Recently, several time of flowering ( Tof ) loci have been reported other than earlier known E loci (Dong, Cheng, et al, 2021; Dong, Fang, et al, 2021; Fang et al, 2017; Kou et al, 2022; Lu et al, 2020).…”

“…Candidate gene analysis of Tof18 identified a SOC1 homologue with conditions early flowering and lesser stem node number in LD as well as SD conditions. Of the two SOC1 homologues present in soybean, SOC1a at Tof18 , had shown stronger effect on time of flowering and stem node number compared to SOC1b (Kou et al, 2022). Double mutants of SOC1a and SOC1b showed stronger functional effect than either of the single mutants.…”

Photoperiod trait: Insight in molecular mechanism for growth and maturity adaptation of soybean (Glycine max) to different latitudes

et al. 2022

Soybeans cover a vast geographical region of 53°N to 40°S latitudes, but individual genotypes have a very narrow latitudinal adaptation of ~200 km due to photoperiodic limitations. Fourteen soybean maturity groups (MG0000‐X) of Northern America have genotypes adapted to very long (MG0000) to short (X) day length conditions. Photoperiod not only affects flowering but other agronomic traits also. Several maturity genes have been mapped, and 12 genes related to the photoperiodic network (E1, E2, E3, E4, J, FT2a, FT5a, Tof5, Tof11, Tof12, Tof16 and Tof18) have been functionally characterized. The role of the paralogues of functionally characterized genes (E1Ls, COs, PRRs, FULs, SOCs and FTs) is being recently elucidated. Allelic diversity at photoperiodic loci confers latitude specific adaptation. Molecular models (common allelic combination present in an MG) have been developed for different MG using E genes but require refining by the addition of other functionally characterized genes to fully explain the flowering and maturity, especially in MG V to X. Three interacting modules PHYA‐E1, GI‐CO and miRNA‐dependent have been developed to elucidate the flowering mechanism in soybean.

Stem elongation has a major influence on plant height and has been a key trait targeted in crop improvement, as illustrated by the green revolution. Particularly in cereal crops, there is a growing awareness of how genetic variation for elongation may be applied to specific challenges in production and may interact with other aspects of development. In comparison, this understanding is less developed in legume crops despite their significance in global agriculture and may have additional implications considering their distinct differences in growth habit and inflorescence structure. This review outlines the relevance of stem elongation in legume crops, provides an overview of its genetic control, and concludes with a discussion of potential interactions with other production traits, including stress tolerance and symbioses.
