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.

摘要

氨基酸/植物生长素通透酶（AAAP）基因家族在长距离氨基酸运输中起重要作用，并参与植物胁迫反应和各种发育过程。AAAP家族的功能已在多种生物中广泛讨论，而草莓（Fragaria vesca）中该家族的详细信息尚未报道。在这项研究中，我们在草莓基因组中鉴定出45个AAAP基因。系统发育分析表明，草莓和拟南芥的AAAPs分为八类。AAAP家族的表达分析表明，AAAP基因在花和果实的不同发育阶段差异表达，并在炭疽菌炭疽病后被显着诱导。感染。我们的研究提供了对草莓AAAP家族的全面了解，并证明了其在抗病性中的潜在作用，为进一步的研究提供了更多参考。
