The PIN family is a type of important carrier elements that regulate the polar transportation of auxin. The PIN genes encode auxin efflux carriers with multiple transmembrane domains that mediate auxin transport in plants. However, there is a lack of systematic research in the genome of complexity Brassica napus. In this study, the BnPIN genes were screened from the Brassica Database using bioinformatics, and study on molecular characteristics of BnPIN proteins, such as copy number variations, transmembrane domains, conserved motifs, chromosoma...
