<i>BnaC09.tfl1</i> controls determinate inflorescence trait in <i>Brassica napus</i>.

ABSTRACT: Determinate inflorescence is indeed a pivotal agricultural characteristic in crops, notably impacting the architecture modification of Brassica napus (AACC, 2n = 38). Previous study identified a crucial gene Bnsdt2 that encodes the transcription factor BnaC09.TFL1 (Terminal Flower 1). Here by two alleles were cloned and sequenced from indeterminate 2982 and determinate 4769, respectively, we found that BnaC09.TFL1 harbors two T/C and G/C non-synonymous mutations in exon 1, and contains sixty-six differences in a 1.9 Kb promoter sequence. Subsequently, BnaC09.TFL1 was introduced into B. napus 571 line by genetic complementation and overexpression, transgenic plants 571^CTO lines and 571^TClines were all restored to the ind
