The results of the phylogeny relationship showed that ARF genes of pepper could be divided into Class I and II and could be further divided into seven sub-groups: Ia, Ib, Ic, Id, Ie, IIa and IIb. The results of gene structure showed that ARF gene family members were composed of 1-15 exons, and for each gene expression level of different tissues at different developmental stages revealed that the gene family had certain expression specificity. The qRT-PCR uncovered that high salt stress could significantly activate and inhibit the expression ofARF gene family.展开更多
