Monocot cereals develop a complex root system comprising embryonic roots at an early seedling stage and postembryonic roots which make up the fibrous root system of adult crops. In the model cereals maize, rice, and barley a number of mutants affecting root development have been identified in the past and a subset of the affected genes have been recently cloned and functionally characterized. The present review summarizes genetic and molecular data of cereal root mutants impaired in the elongation or initiation of embryonic and postembryonic roots and the elongation of root hairs for which the affected genes have been recently cloned.
单子叶谷物在幼苗早期发育出一个复杂的根系，包括胚根和胚后根，后者构成了成年作物的须根系。在模式谷物玉米、水稻和大麦中，过去已经鉴定出许多影响根系发育的突变体，最近已经克隆了一部分受影响的基因并对其进行了功能表征。本综述总结了谷物根系突变体的遗传和分子数据，这些突变体在胚根和胚后根的伸长或起始以及根毛伸长方面存在缺陷，且最近已克隆出受影响的基因。
