摘      要：Flower development and plant architecture determine the efficiency of mechanized harvest and seed yield in Brassica *** TERMINAL FLOWER 1(AtTFL1)is a regulator of flower development in Arabidopsis thaliana,the function and regulatory mechanism of TFL1 orthologs in *** remains *** BnTFL1 paralogs in the genome of the *** inbred line‘K407’showed steadily increasing expression during ***/Cas-induced mutagenesis of up to four BnTFL1 paralogs resulted in early flowering and alteration of plant architecture,whereas seed yield was not altered in BnTFL1 single,double,or triple *** BnTFL1 paralogs,but not ***1,showed an additive and conserved effect on regulating flowering time,total and terminal flower number,and plant ***1 regulates flower development by interacting with *** through the protein ***14nu,resulting in the transcriptional repression of floral integrator and floral meristem identity *** findings about the regulatory network controlling flower development and plant architecture present a promising route to modifying these traits in ***.
