毛状体是一种特殊的表皮细胞，规律性地分布在拟南芥植物的叶片上。在叶片发育过程中，每个毛状体都经历了细胞形态发生，形成了非常精确的结构。我们已经分离并鉴定了代表21个不同基因的70多个毛状体突变体。通过分析它们的细胞表型，可以确定毛状体发育的具体步骤。尽管这些步骤通常是按时间顺序发生的，但基因解剖表明，成熟细胞的形态在很大程度上是在独立的事件中组装的。这些结果提出了一种特殊细胞类型如何起源于统一细胞层的模型。
Trichomes are specialized epidermal cells that are regularly distributed on the leaves of Arabidopsis plants. During leaf development, each trichome undergoes cell morphogenesis, resulting in a very precise architecture. We have isolated and characterized more than 70 trichome mutants that represent 21 different genes. By analyzing their cellular phenotypes, it has been possible to define specific steps in trichome development. Although these steps normally occur in a temporal sequence, genetic dissection indicates that the morphology of the mature cell is largely assembled in independent events. The results suggest a model of how a specialized cell type originates from a uniform cell layer.
