Phylogeny relationship (a), exon-intron organization b) of the amino acid permease (AAP) genes and enrichment analysis (c) of the cis-acting regulatory elements (CREs) in the AAP promoter regions in Brassica napus. For each AAP, a 2.0-kb genomic sequence in the upstream from the start codon (ATG) was downloaded from the TAIR (https://www.arabidopsis.org/) website and B. napus Genome Browser (http://www.genoscope.cns.fr/brassicanapus/) [24]. Subsequently, we submitted these sequences to the PLACE v. 30.0 (http://www.dna.affrc.go.jp/PLACE/) program [35] to identify putative CREs and calculate the CRE number along the 2.0 kb gene promoter region. In the scatter plot of c, the larger the circle sizes, the more the corresponding CREs
