Genome-wide identification and characterization of the Hsp70 gene family in allopolyploid rapeseed (Brassica napus L.) compared with its diploid progenitors.

ABSTRACT: Heat shock protein 70 (Hsp70) plays an essential role in plant growth and development, as well as stress response. Rapeseed (Brassica napus L.) originated from recently interspecific hybridization between Brassica rapa and Brassica oleracea. In this study, a total of 47 Hsp70 genes were identified in B. napus (A_nA_nC_nC_n genome), including 22 genes from A_n subgenome and 25 genes from C_n subgenome. Meanwhile, 29 and 20 Hsp70 genes were explored in B. rapa (A_rA_r genome) and B. oleracea (C_oC_o genome), respectively. Based on phylogenetic analysis, 114 Hsp70 proteins derived from B. napus, B. rapa, B. oleracea an
