The complex and coordinated regulation of flowering has high ecological agricultural significance. maturity locus E1 a large impact on time in soybean, but the molecular basis for is largely unknown. Through positional cloning, we delimited to 17.4-kb region containing an intron-free gene ( ). protein contains putative bipartite nuclear localization signal distantly related B3 domain. In recessive allele, nonsynonymous substitution occurred signal, leading loss specificity earlier flowering....
Flowering is indicative of the transition from vegetative to reproductive phase, a critical event in life cycle plants. In soybean (Glycine max), flowering quantitative trait locus, FT2, corresponding maturity locus E2, was detected recombinant inbred lines (RILs) derived varieties "Misuzudaizu" (ft2/ft2; JP28856) and "Moshidou Gong 503" (FT2/FT2; JP27603). A map-based cloning strategy using progeny residual heterozygous line (RHL) RIL employed isolate gene responsible for this locus....
Photosensitivity plays an essential role in the response of plants to their changing environments throughout life cycle. In soybean [Glycine max (L.) Merrill], several associations between photosensitivity and maturity loci are known, but only limited information at molecular level is available. The FT3 locus one quantitative trait (QTL) for flowering time that corresponds E3. To identify gene responsible this QTL, a map-based cloning strategy was undertaken. One phytochrome A (GmPhyA3)...
FLOWERING LOCUS T (FT) is a key flowering integrator in Arabidopsis (Arabidopsis thaliana), with homologs that encode florigens many plant species regardless of the type photoperiodic response. We identified 10 FT homologs, which were arranged as five pairs linked genes different homoeologous chromosomal regions, soybean (Glycine max), paleopolyploid species. Two GmFT2a and GmFT5a, highly up-regulated under short-day (SD) conditions (inductive for soybean) had diurnal expression patterns...
Classical genetic analysis has revealed that the determinate habit of soybean (Glycine max) is controlled by a recessive allele at stem (Dt1) locus. To dissect molecular basis habit, we isolated two orthologs pea (Pisum sativum) TERMINAL FLOWER1a, GmTFL1a and GmTFL1b, from genome. Mapping indicated GmTFL1b candidate for Dt1. Despite their high amino acid identity, genes had different transcriptional profiles. was expressed in root shoot apical meristems (SAMs), whereas mainly immature seed....
Abstract Background Absence of or low sensitivity to photoperiod is necessary for short-day crops, such as rice and soybean, adapt high latitudes. Photoperiod insensitivity in soybeans controlled by two genetic systems involves three important maturity genes: E1 , a repressor soybean orthologs Arabidopsis FLOWERING LOCUS T ( GmFT2a GmFT5a ), E3 E4 which are phytochrome A genes. To elucidate the diverse mechanisms underlying we assessed genotypes four genes through ) early-flowering...
The timing of flowering has a direct impact on successful seed production in plants. Flowering soybean (Glycine max) is controlled by several E loci, and previous studies identified the genes responsible for loci E1, E2, E3 E4. However, natural variation these not been fully elucidated. aims this study were identification new alleles, establishment allele diagnoses, examination allelic combinations adaptability, analysis integrated effect flowering. sequences their flanking regions...
The major maturity gene E1 has the most prominent effect on flowering time and photoperiod sensitivity of soybean, but pathway mediated by is largely unknown. Here, we found expression GmFT4, a homolog Flowering Locus T, was strongly up-regulated in transgenic soybean overexpressing E1, whereas activators, GmFT2a GmFT5a, suppressed. GmFT4 long days exhibiting diurnal rhythm, down-regulated short days. Notably, basal level elevated when transferred to continous light, repressed continuous...
Soybean flowering and maturation are strictly regulated by photoperiod. Photoperiod-sensitive soybean varieties can undergo reversion when switched from short-day (SD) to long-day (LD) conditions, suggesting the presence of a 'floral-inhibitor' under LD conditions. We combined gene expression profiling with study transgenic plants confirmed that GmFT1a, Flowering Locus T (FT) homolog, is floral inhibitor. GmFT1a expressed specifically in leaves, similar flowering-promoting FT homologs...
CONSTANS (CO) has a central role in the photoperiod response mechanism Arabidopsis. However, functions of legume CO genes controlling flowering remain unknown. Here, we analyze expression patterns E1, E2 and GmCOL1a/1b using near-isogenic lines (NILs), further flowering-related gmcol1b mutants GmCOL1a-overexpressing plants. Our data showed that both E3 E4 up-regulate E1 expression, with effect on being greater than E1. was up-regulated by but down-regulated were E2, E4. Although spatial...
Soybean (Glycine max) is highly sensitive to photoperiod, which affects flowering time and plant architecture thus limits the distribution range of elite soybean cultivars. The major maturity gene E1 confers most prominent effect on photoperiod sensitivity, but its downstream signaling pathway remains largely unknown. Here, we confirm that encoded protein a transcriptional repressor. expression seven GmMDE genes max MADS-box downregulated by E1) was suppressed when overexpressed promoted...
Soybean [Glycine max (L.) Merrill] is the most important leguminous crop in world due to its high contents of high-quality protein and oil for human animal consumption as well industrial uses. An accurate saturated genetic linkage map soybean an essential tool studies on modern genomics. In order update a F2 population derived from cross between Misuzudaizu Moshidou Gong 503 make it more informative useful genome research community, total 318 AFLP, 121 SSR, 108 RFLP, 126 STS markers were...
The time to flowering and maturity are ecologically agronomically important traits for soybean landrace cultivar adaptation. As a typical short-day crop, long day conditions in the high-latitude regions require cultivars with photoperiod insensitivity that can mature before frost. Although molecular basis of four major E loci (E1 E4) have been deciphered, it is not quite clear whether, or what degree, genetic variation expression level genes associated cultivars. In this study, we genotyped...
Gene regulatory networks involved in flowering time and photoperiodic responses legumes remain unknown. Although the major maturity gene E1 has been successfully deciphered soybean, knowledge on functional conservation of this is limited to a certain extent homologs legumes. The ectopic expression Phvul.009G204600 (PvE1L), an homolog from common bean, delayed onset soybean. By contrast, Medtr2g058520 (MtE1L) Medicago truncatula did not affect Characterization late-flowering mte1l mutant...
The pseudo response regulator (PRR) gene is an important component of the core oscillator involved in plant circadian rhythms and plays role regulating growth development stress responses. In this study, we investigated function GmPRR7b by overexpression editing approaches. It was found that a delaying flowering. While overexpressing plants showed significantly delayed flowering compared to untransformed WT, edited flowered earlier than control WT. On basis previous research results...
The number and distribution of branches in soybean plants influence seed yield through effects on the efficiency light utilization as well tolerance to lodging. We have developed recombinant inbred lines (RILs) from a cross between two experimental determinant lines, which differ branching number. 172 RILs were divided into four maturity groups according their alleles for loci, E1 E3, planted separately avoid confounding competition. late-maturity RIL with genotype grown different locations,...
