Genome-Wide Identification and Expression Analysis of the Eif Family Genes from Brassica Rapa in Response to Tumv Resistance
Brassica rapa is a very important vegetable all over the world. However, turnip mosaic virus (TuMV) as the serious virus to B. rapa , the harm from TuMV to production could not be completely controlled at present. In this study, the genome-wide identification and expression detection of the eIF family genes from B. rapa in response to TuMV resistance were analyzed, including identification of eIF family genes, chromosomal distribution, identification of the physicochemical properties, phylogenetic analysis, evolutionary analysis, conserved analysis, three-dimensional (3D) structure and sequence logos analysis, and expression characterization and differential metabolite analysis of eIF family genes in resistant/susceptible lines, which may further prove the whole-genome tripling (WGT) event in B. rapa evolution, and provide the evidence for functional redundancy and functional loss of multicopy eIF genes in evolution. qRT-PCR analysis revealed that the relative expressions of eIF genes in susceptible line (80461) were higher than those in resistant line (80124), which may prove that when TuMV infected host plants, the eIF genes could combine with virus mRNA 5’ end cap structure, and promote the virus mRNA translation initiation in the susceptible B. rapa line. This study may lay a new theoretical foundation for revealing eIF family gene resistance to TuMV in B. rapa , as well as advanced our understanding of virus−host interactions
