Abstract

Amino acid transporters (AATs) are integral membrane proteins and have several functions, including transporting amino acids across cellular membranes. They are critical for plant growth and development. This study comprehensively identified AAT-encoding genes in tomato (), which is an important vegetable crop and serves as a model for fleshy fruit development. In this study, 88 genes were identified in the genome and grouped into 12 subfamilies, based on previously identified AATs in , rice (), and potato () plants. Chromosomal localization revealed that AAT () genes are distributed on the 12 chromosomes. Segmental duplication events contribute mainly to the expansion of genes and about 32% (29 genes) of genes were found to originate from this type of event. Expression profiles of genes in various tissues of using RNA sequencing data from the Tomato Functional Genomics Database (http://ted.bti.cornell.edu/) showed that genes exhibited tissue-specific expression patterns. Comprehensive data generated in this study will provide a platform for further studies on the SlAAT gene family and will facilitate the functional characterization of genes.

摘要

氨基酸转运蛋白（AATs）是整合膜蛋白，具有多种功能，包括跨细胞膜转运氨基酸。它们对植物的生长和发育至关重要。本研究全面鉴定了番茄中的AAT编码基因，番茄是一种重要的蔬菜作物，也是肉质果实发育的模型。在本研究中，根据先前在拟南芥、水稻和马铃薯植物中鉴定出的AATs，在番茄基因组中鉴定出88个基因，并将其分为12个亚家族。染色体定位显示，番茄AAT（SlAAT）基因分布在12条染色体上。片段重复事件主要促成了SlAAT基因的扩增，约32%（29个基因）的SlAAT基因被发现起源于此类事件。利用来自番茄功能基因组数据库（http://ted.bti.cornell.edu/）的RNA测序数据，分析SlAAT基因在番茄不同组织中的表达谱，结果表明SlAAT基因呈现出组织特异性表达模式。本研究产生的综合数据将为进一步研究SlAAT基因家族提供一个平台，并有助于对SlAAT基因进行功能表征。
