Cytoplasmic male sterility (CMS) factors have long been known in some wild plants, and also in some domesticated species, where they are used to produce plants to be used as maternal parents, for example to breed hybrids that display hybrid vigor. Their origins have been mystifying, and now a study recently published in Cell Research helps understand how one widely-used rice CMS factor evolved.
细胞质雄性不育(CMS)因子在一些野生植物中早已为人所知,在一些驯化物种中也存在,这些因子被用于生产作为母本的植物,例如培育表现杂种优势的杂种。它们的起源一直令人费解,而最近发表在《Cell Research》上的一项研究有助于理解一种广泛使用的水稻 CMS 因子是如何进化的。
