Genome-wide identification and expression analysis of the AAAP family in Fragaria vesca

Abstract

The amino acid/auxin permease (AAAP) gene family plays a significant role in the long-distance amino acid transport and is involved in plant stress responses and various developmental processes. The functions of the AAAP family have been extensively discussed in multiple organisms, whereas detailed information of this family in strawberry (Fragaria vesca) has not been reported yet. In this study, we identified 45 AAAP genes in the strawberry genome. Phylogenetic analysis indicated that AAAPs from strawberry and Arabidopsis were clustered into eight groups. Expression analysis of the AAAP family showed that AAAP genes were expressed differentially in different developmental stages of flower and fruit, and were significantly induced after Colletotrichum gloeosporioides infection. Our study provides a comprehensive understanding of the strawberry AAAP family and demonstrates their potential roles in disease resistance, providing more reference for further research.
