Genome-Wide Identification of the CAT Genes and Molecular Characterization of Their Transcriptional Responses to Various Nutrient Stresses in Allotetraploid Rapeseed.

ABSTRACT: Brassica napus is an important oil crop in China and has a great demand for nitrogen nutrients. Cationic amino acid transporters (CAT) play a key role in amino acid absorption and transport in plants. However, the CATs family has not been reported in B. napus so far. In this study, genome-wide analysis identified 22 CAT members in the B. napus genome. Based on phylogenetic and synteny analysis, BnaCATs were classified into four groups (Group I-Group IV). The members in the same subgroups showed similar physiochemical characteristics and intron/exon and motif patterns. By evaluating cis-elements in the promoter regions, we identified some cis-elements related to hormones, stress and plant development. Darwin's evolutionary analysis ind
