The actin depolymerizing factor (ADF) proteins have growth, development, defense-related and growth regulatory functions in plants. The present study used genome-wide analysis to investigate family genes in tomato. Eleven tomato genes were identified and differential expression patterns were found in different organs. was preferentially expressed in roots, suggesting its function in root development. , and were predominately expressed in the flowers compared to the other organs and specifically in the stamen compared to other flower parts, indicating their potential roles in pollen development. The comparatively higher expression of and at early fruit developmental stages might implicate them in determining final fruit size. and had relatively higher levels of expression five days after the breaker stage of fruit development, suggesting their possible role in fruit ripening. Notably, six genes were induced by cold and heat, seven by drought, five by NaCl, and four each by abscisic acid (ABA), jasmonic acid (JA) and wounding treatments. The differential expression patterns of the genes under different types of stresses suggested their function in stress tolerance in tomato plants. Our results will be helpful for the functional characterization of genes during organ and fruit development of tomato under different stresses.
肌动蛋白解聚因子（ADF）蛋白在植物中具有生长、发育、防御相关及生长调节功能。本研究采用全基因组分析方法对番茄中的该家族基因进行研究。共鉴定出11个番茄基因，并发现其在不同器官中存在差异表达模式。[基因名称1]在根中优先表达，表明其在根发育中的功能。[基因名称2]、[基因名称3]和[基因名称4]相比于其他器官在花中大量表达，相比于花的其他部分在雄蕊中特异性表达，表明它们在花粉发育中的潜在作用。[基因名称5]和[基因名称6]在果实发育早期阶段表达相对较高，这可能意味着它们在决定最终果实大小方面发挥作用。[基因名称7]和[基因名称8]在果实发育破色期后五天表达水平相对较高，表明它们在果实成熟中可能发挥的作用。值得注意的是，6个基因受冷和热诱导，7个受干旱诱导，5个受NaCl诱导，4个分别受脱落酸（ABA）、茉莉酸（JA）和创伤处理诱导。这些基因在不同类型胁迫下的差异表达模式表明它们在番茄植株胁迫耐受性方面的功能。我们的结果将有助于在不同胁迫下番茄器官和果实发育过程中对这些基因进行功能表征。
