“…Given that changes in Glyma.02G304700 can lead to changes in leaf color and chlorophyll content, photosynthetic parameters, photomorphogenesis, and flowering time, we performed a detailed analysis of genes potentially involved in photosynthesis [ 28 ] and flowering time [ 29 ]. We used the 254 Chlamydomonas reinhardtii genes with potential functions in photosynthesis [ 28 ] as queries in a BLAST search of the soybean V275 genome, which led to the identification of 158 putative homologs.…”

Plants photoreceptors perceive changes in light quality and intensity and thereby regulate plant vegetative growth and reproductive development. By screening a γ irradiation-induced mutant library of the soybean (Glycine max) cultivar “Dongsheng 7”, we identified Gmeny, a mutant with elongated nodes, yellowed leaves, decreased chlorophyll contents, altered photosynthetic performance, and early maturation. An analysis of bulked DNA and RNA data sampled from a population segregating for Gmeny, using the BVF-IGV pipeline established in our laboratory, identified a 10 bp deletion in the first exon of the candidate gene Glyma.02G304700. The causative mutation was verified by a variation analysis of over 500 genes in the candidate gene region and an association analysis, performed using two populations segregating for Gmeny. Glyma.02G304700 (GmHY2a) is a homolog of AtHY2a in Arabidopsis thaliana, which encodes a PΦB synthase involved in the biosynthesis of phytochrome. A transcriptome analysis of Gmeny using the Kyoto Encyclopedia of Genes and Genomes (KEGG) revealed changes in multiple functional pathways, including photosynthesis, gibberellic acid (GA) signaling, and flowering time, which may explain the observed mutant phenotypes. Further studies on the function of GmHY2a and its homologs will help us to understand its profound regulatory effects on photosynthesis, photomorphogenesis, and flowering time.

“…On the other hand, in the pairs derived from F 4 plants #83 and #40, the flowering date of plants carrying the 'Suzuotome' allele was two days earlier than for plants carrying the 'Fukuyutaka' allele (Table 2). The detected QTL regions on chromosome 6 included at least three loci which were associated with flowering-time: the E1, E7 and QNE1 loci (Abe et al 2003, Cober and Voldeng 2001, Cregan et al 1999, Molnar et al 2003, Xia et al 2022) (Fig. 5).…”

In mechanically harvested soybean, green stem disorder (GSD) is an undesirable trait that causes greenstained seeds, which are graded lower in Japan. To obtain DNA markers for reduced GSD, we conducted a quantitative trait locus (QTL) analysis for 2 years using F 4 and F 5 lines from a cross between 'Suzuotome' (less GSD) and 'Fukuyutaka' (more GSD). We validated the effect of a detected QTL for GSD by first identifying F 4 or F 5 plants in which one or more markers in the QTL region were heterozygous. The F 5 or F 6 progeny of each plant was used to form a pair consisting of two groups in which the QTL region was homozygous for either the 'Suzuotome' or 'Fukuyutaka' allele in a similar genetic background, and the two groups within each pair were compared for GSD. Over 3 years of testing, the 'Suzuotome' allele of a QTL on chromosome 6 was found to reduce the level of GSD. This novel QTL was mapped to the region around DNA marker W06_0130, and was not closely linked to QTLs for important agronomic traits including yield components. Using this marker, the low level of GSD from 'Suzuotome' could be conferred to 'Fukuyutaka' or other high-GSD cultivars.

“…A recent study revealed that Tof4/E1La has a function similar to E1, which directly associates with the promoters of Tof5 , FT2a , and FT5a to suppress their transcription (Dong et al 2023 ). In addition, Tof18 directly activates the expression of FT2a and FT5a in leaves (Kou et al 2022 ), and QNE1 can form protein complexes with FT2a and FT5a (Xia et al 2022 ). Furthermore, FT2a and FT5a interact with FDLs (FLOWERING LOCUS D-LIKE) to induce the expression of the floral meristem identity gene APETALA1 ( AP1 ) to promote flowering (Chen et al 2020 ; Li et al 2021 ; Nan et al 2014 ; Yue et al 2021 ).…”

Soybean (Glycine max) is an economically important crop worldwide, serving as a major source of oil and protein for human consumption and animal feed. Cultivated soybean was domesticated from wild soybean (Glycine soja) which both species are highly sensitive to photoperiod and can grow over a wide geographical range. The extensive ecological adaptation of wild and cultivated soybean has been facilitated by a series of genes represented as quantitative trait loci (QTLs) that control photoperiodic flowering and maturation. Here, we review the molecular and genetic basis underlying the regulation of photoperiodic flowering in soybean. Soybean has experienced both natural and artificial selection during adaptation to different latitudes, resulting in differential molecular and evolutionary mechanisms between wild and cultivated soybean. The in-depth study of natural and artificial selection for the photoperiodic adaptability of wild and cultivated soybean provides an important theoretical and practical basis for enhancing soybean adaptability and yield via molecular breeding. In addition, we discuss the possible origin of wild soybean, current challenges, and future research directions in this important topic.
