The ATP-binding cassette (ABC) transporter gene family plays a vital role in substance transportation, including secondary metabolites, and phytohormones across membranous structures. It is still uncovered in potato (Solanum tuberosum), grown worldwide as a 3^rd important food crop. The current study identified a total of 54 Stabc genes in potato genome. The accumulative phylogenetic tree of Stabc with arabidopsis, divided into eight groups (ABCA to ABCH). ABCG was the most prominent group covering 90% of Stabc genes, followed by ABCB group. The number and architecture of exon–intron varied from gene to gene. In addition, the presence of stress-responsive elements in the regulatory regions depicted their role in environmental stress. Furthermore, the tissue-specific and stress-specific expression profiling of Stabc genes and their validation through real-time-qPCR analysis revealed their role in development and stress. The presented results provided useful information for further functional analysis of Stabc genes and can also use as a reference study for other important crops.

ATP 结合盒 (ABC) 转运蛋白基因家族在物质转运中起着至关重要的作用，包括次生代谢物和跨膜结构的植物激素。它仍然存在于马铃薯（马铃薯）中，马铃薯是世界范围内种植的^第三大重要粮食作物。目前的研究在马铃薯基因组中鉴定了总共 54 个Stabc基因。拟南芥Stabc的累积系统发育树，分为8个组（ABCA到ABCH）。ABCG 是最突出的组，覆盖了 90% 的Stabc基因，其次是ABCB组。外显子-内含子的数量和结构因基因而异。此外，调节区域中应激反应元件的存在描述了它们在环境应激中的作用。此外， Stabc基因的组织特异性和应激特异性表达谱及其通过实时 qPCR 分析的验证揭示了它们在发育和应激中的作用。所呈现的结果为进一步对Stabc基因进行功能分析提供了有用的信息，也可以用作其他重要作物的参考研究。
