Alfin-like (AL) transcription factors are a family of plant-specific genes with a PHD-finger-like structural domain at the C-terminus and a DUF3594 structural domain at the N-terminus that play important roles in plant development and stress response. In the present study, genome-wide identification and analysis were performed of the AL protein family in cultivated tomato () and three wild relatives (, and ) to evaluate their response to different abiotic stresses. A total of 39 were identified and classified into four groups and based on phylogenetic tree and evolutionary analysis were shown to have formed prior to the differentiation of monocotyledons and dicots. Moreover, -acting element analysis revealed that various phytohormone response and abiotic stress response elements were highly existed in tomato. In addition, further analysis of the gene revealed that its expression was induced by drought and salt stresses and localized to the nucleus. In conclusion, our findings concerning genes provide useful information for further studies on their functions and regulatory mechanisms and provide theoretical references for studying gene response to abiotic stresses in plants.
类苜蓿（AL）转录因子是一类植物特有的基因家族，其C端具有一个类PHD结构域，N端具有一个DUF3594结构域，在植物发育和胁迫响应中发挥重要作用。在本研究中，对栽培番茄（）和三个野生近缘种（、和）中的AL蛋白家族进行了全基因组鉴定和分析，以评估它们对不同非生物胁迫的响应。共鉴定出39个，并分为四组，基于系统发育树和进化分析表明它们在单子叶植物和双子叶植物分化之前就已形成。此外，顺式作用元件分析表明，番茄中存在多种植物激素响应和非生物胁迫响应元件。另外，对基因的进一步分析表明，其表达受干旱和盐胁迫诱导，并定位于细胞核。总之，我们关于基因的研究结果为进一步研究其功能和调控机制提供了有用信息，并为研究植物中基因对非生物胁迫的响应提供了理论参考。
