Genome-wide identification and expression analysis of the AAAP family in <i>Fragaria vesca</i>

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 (<i>Fragaria vesca</i>) 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 <i>Arabidopsis</i> 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 <i>Colletotrichum gloeosporioides</i> 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.氨基酸/生长素通透酶（amino acid/auxin permease，AAAP）基因家族在氨基酸长距离转运中发挥关键作用，同时参与植物胁迫响应及多种生长发育进程。目前，AAAP基因家族的功能已在多种生物中被广泛研究，但该家族在森林草莓（*Fragaria vesca*）中的详细信息尚未见报道。本研究从森林草莓基因组中鉴定出45个AAAP基因。系统发育分析表明，森林草莓与拟南芥（*Arabidopsis*）的AAAP蛋白可分为8个进化组。AAAP家族的表达分析显示，其基因在花和果实的不同发育阶段呈现差异化表达，且在胶孢炭疽菌（*Colletotrichum gloeosporioides*）侵染后显著上调。本研究全面解析了森林草莓AAAP基因家族，揭示了其在抗病过程中的潜在功能，为后续相关研究提供了重要参考。
