Through the comparative genomics,a novel LEAFY gene BrLFY1 was identified from the genome of Chinese cabbage(Brassica pekinensis).Its sequence character,phylogenetic relationship with other plant's LFYs and cis-elements were analyzed.The results showed that the genomic sequence of the gene contained 2 introns;its full length coding sequence was 1 260 bp,which encoded a putative 46.38 ku protein.The phylogenetic analysis showed that BrLFY1 was the closest to Raphanus sativus gene RsLFY1,and their homology re...
