ACO is one of the rate-limiting enzymes in the biosynthesis of ethylene, and it plays a critical role in the regulation of plant growth and development. However, the function of genes in cotton is not well studied. In this study, a total of 332 , 187 , and were identified in , , and , respectively. Gene duplication analysis showed that whole-genome duplication (WGD) and tandem duplication were the major forces driving the generation of cotton genes. In the promoters of , there were cis-acting elements responding to stress, phytohormones, light, and circadian factors, indicating the possible involvement of in these processes. Expression and co-expression analyses illustrated that most were not only widely expressed in various tissues but also coexpressed with other genes in response to salt and drought stress. overexpression in promoted flowering and increased salt tolerance. These results provide a comprehensive overview of the genes of cotton and lay the foundation for subsequent functional studies of these genes.
ACO是乙烯生物合成中的限速酶之一，在植物生长发育调控中起关键作用。然而，棉花中该基因的功能尚未得到充分研究。在本研究中，分别在[具体物种1]、[具体物种2]和[具体物种3]中鉴定出了总共332个、187个和[具体数量]个[该基因名称]。基因复制分析表明，全基因组复制（WGD）和串联复制是推动棉花[该基因名称]基因产生的主要力量。在[该基因名称]的启动子中，存在响应胁迫、植物激素、光和昼夜节律因子的顺式作用元件，表明[该基因名称]可能参与这些过程。表达和共表达分析表明，大多数[该基因名称]不仅在各种组织中广泛表达，而且在响应盐和干旱胁迫时与其他基因共表达。在[具体植物]中过表达[该基因名称]促进了开花并提高了耐盐性。这些结果提供了棉花[该基因名称]基因的全面概述，并为这些基因的后续功能研究奠定了基础。
