The root hair development of vascular plants can be divided into 2 major processes, fate determination and hair morphogenesis, and the latter should be governed by the former so as to express the morphogenetic toolkits in a root hair-specific manner. Vascular plants, depending on taxa, show different fate-determining mechanisms for hair cell/non-hair cell fates, which leads to a question whether the downstream mophogenetic regulatory module is diverged accordingly to the upstream fate determiners or not. Our study demonstrates that the module of a transcription factor and a root hair-specific cis-element (RHE) for root hair-specific expression of morphogenetic toolkit genes is conserved in spite of different fate-determing mechanisms.
维管植物的根毛发育可分为两个主要过程，即命运决定和毛形态发生，后者应受前者调控，以便以根毛特异性方式表达形态发生工具包。根据分类群的不同，维管植物在毛细胞/非毛细胞命运的决定机制上表现出差异，这就引发了一个问题，即下游的形态发生调控模块是否会根据上游的命运决定因素而相应地发生分化。我们的研究表明，尽管命运决定机制不同，但用于形态发生工具包基因根毛特异性表达的转录因子和根毛特异性顺式元件（RHE）模块是保守的。
