摘要

Tartary Buckwheat [Fagopyrum tartaricum (L.) Garten, TB] is an annual herb, which has high nutritional value. Amino acid permease (AAP) can extensively absorb and transport various amino acids and participate in a series of physiological processes in plant growth. However, research on AAP genes in Tartary buckwheat remains limited. In this study, a total of 18 FtAAP proteins were identified and categorized into 3 phylogenetic subgroups. There was a similarity in gene structure and motif composition among proteins within the same subset. In addition, a variety of hormone responsive elements and abiotic stress response elements were detected in the promoter region of the FtAAP genes. An analysis of synteny showed that Tartary buckwheat was related to dicotyledons more than monocotyledons. Expression pattern analysis indicated that most FtAAP genes exhibited tissue-specific expression patterns. The expression of FtAAP genes exhibited significant responsiveness to diverse phytohormone treatments, including ABA, IAA, GA, SA, and MeJA by RT-qPCR analysis. This study integrated phylogenetic analysis with genome-wide expression profiling to provide valuable information for understanding the functional characteristics of AAP genes in Tartary buckwheat.
