Male Sterility in Maize: A Precise Dialogue between the Mitochondria and Nucleus

摘要

Male sterility has been widely utilized in plant hybrid breeding.Genic male sterility (GMS) and cytoplasmic male sterility (CMS)are two types of male sterility in plants.GMS is caused by nuclear genes alone, but CMS is determined by the mitochondrial genome, whereas the latter can be suppressed or counteracted by nuclear genes known as restorer-of-fertility (Rt) genes.
