Genome-wide identification and analysis of the EIN3/EIL gene family in allotetraploid Brassica napus reveal its potential advantages during polyploidization.

ABSTRACT:

Background

Polyploidization is a common event in the evolutionary history of angiosperms, and there will be some changes in the genomes of plants other than a simple genomic doubling after polyploidization. Allotetraploid Brassica napus and its diploid progenitors (B. rapa and B. oleracea) are a good group for studying the problems associated with polyploidization. On the other hand, the EIN3/EIL gene family is an important gene family in plants, all members of which are key genes in the ethylene signaling pathway. Until now, the EIN3/EIL gene family in B. napus and its diploid progenitors have been largely unknown, so it is necessary to comprehensively identify and analyze this gene family.

Results

In this study, 13, 7 and 7 EIN3/EIL genes were identified in B. napus (2n =
