Genome-wide identification, structural analysis and new insights into late embryogenesis abundant (LEA) gene family formation pattern in Brassica napus Yu Liang1,2, Ziyi Xiong1, Jianxiao Zheng1, Dongyang Xu1, Zeyang Zhu1, Jun Xiang2, Jianping Gan2, Nadia Raboanatahiry1, Yongtai Yin1 & Maoteng Li1,2 Late embryogenesis abundant (LEA) proteins are a diverse and large group of polypeptides that play important roles in desiccation and freezing tolerance in plants. The LEA family has been systematically characterized in some plants but not Brassica napus. In this study, 108 BnLEA genes were identified in the B. napus genome and classified into eight families based on their conserved domains. Protein sequence alignments revealed an abundance of alanine, lysine and glutamic acid residues in BnLEA proteins. The BnLEA gene structure has few introns (
