主 题:Soybean TFL1c TFL1d Flowering time
摘 要:Flowering time is a key agronomic trait that directly affect the adaptation and yield of *** whole genome duplications,about 75%of genes being represented by multiple copies in *** are four TERMINAL FLOWER 1(TFL1)genes in soybean,and the TFL1b(Dt1)has been characterized as the determinant of stem growth *** function of other TFL1 homologs in soybean is still ***,we generated knockout mutants by CRISPR/Cas9 genome editing technology and found that the tfl1c/tfl1d double mutants flowered significantly earlier than wild-type *** investigated that TFL1c and TFL1d could physically interact with the b ZIP transcription factor FDc1 and bind to the promoter of APETALA1a(AP1a).RNA-seq and q RT-PCR analyses indicated that TFL1c and TFL1d repressed the expressions of the four AP1 homologs and delayed the flowering time in *** two genes play important roles in the regulation of flowering time in soybean and mainly act as the flowering inhibitors under long-day *** results identify novel components in the flowering-time regulation network of soybean and will be invaluable for molecular breeding of improved soybean yield.
