COR413 (cold- regulated 413) is an important gene family involved in response to cold stress. In this study, COR413 family genes of Brassica napus, B. oleracea and B. rapa were investigated. Among them, 11 genes were identified in B. napus, 6 genes were found in B. oleracea and 6 in B. rapa. Most of them were located on plasma membrane and chloroplast membrane. COR413 proteins were highly conserved and were hydrophobic and stable with no signal peptides, containing tryptophan which was special in COR family. Tissue specific expression analysis on Arabidopsis, B. oleracea and B. rapa showed that most COR413 genes in subfamily I were highly ex? pressed in roots and leaves, and genes in subfamily II were highly expressed in stems and leaves.
