Characterization and Expression Analysis of ERF Genes in Fragaria vesca Suggest Different Divergences of Tandem ERF Duplicates.

ABSTRACT: Ethylene-responsive factors (ERFs) play important roles in plant growth and development and in responses to abiotic stresses. However, little information was available about the ERF genes in woodland strawberry (Fragaria vesca), a genetic model plant for the Fragaria genus and Rosaceae family. In this study, 91 FveERF genes were identified, including 35 arrayed in tandem, indicating that tandem duplication is a major mechanism for the expansion of the FveERF family. According to their phylogenetic relationships with AtERFs from Arabidopsis thaliana, the tandem FveERF genes could be grouped into ancestral and lineage-specific tandem ones. The ancestral tandem FveERFs are likely derived from tandem duplications that occurred in the comm
