Myosin protein as a molecular motor, binding with Actin, plays a significant role in various physiological activities such as cell division, movement, migration, and morphology; however, there are only a few studies on plant Myosin gene family, particularly in cotton. A total of 114 Myosin genes were found in , , , and . All Myosins could be grouped into six groups, and for each group of these genes, similar gene structures are found. Study of evolution suggested that the whole genome duplications event occurring about 13-20 MYA (millions of years ago) is the key explanation for Myosins expanse in cotton. Cis-element and qPCR analysis revealed that plant hormones such as abscisic acid, methyl jasmonate, and salicylic acid can control the expression of Myosins. This research provides useful information on the function of Myosin genes in regulating plant growth, production, and fiber elongation for further studies.
肌球蛋白蛋白作为一种分子马达，与肌动蛋白结合，在细胞分裂、运动、迁移和形态等各种生理活动中发挥着重要作用；然而，目前仅有少数关于植物肌球蛋白基因家族的研究，特别是在棉花中。在 、 、 、 中发现了总共 114 种肌球蛋白基因。所有肌球蛋白都可以分为六个组，对于这些基因的每一组，都发现了类似的基因结构。进化研究表明，大约 13-20 亿年前（百万年前）发生的全基因组加倍事件是棉花中肌球蛋白扩张的关键解释。顺式元件和 qPCR 分析表明，植物激素如脱落酸、茉莉酸甲酯和水杨酸可以控制肌球蛋白的表达。这项研究为进一步研究肌球蛋白基因在调节植物生长、生产和纤维伸长中的功能提供了有用的信息。
