根独立起源于真叶植物（蕨类植物和种子植物）和石松植物；然而，根起始的分子进化途径仍然难以捉摸。通过对蕨类植物 Ceratopteris richardii 和种子植物的分析，我们发现涉及生长素、中间进化枝 WUSCHEL 相关同源盒 (IC-WOX) 基因和 WUSCHEL 进化枝 WOX (WC-WOX) 基因的分子途径在根起始过程中可以保守。我们认为，根起始中的“生长素>IC-WOX>WC-WOX”模块可能在根的第二次起源期间出现在真叶植物的共同祖先中，并且该模块在蕨类植物和种子植物中不同根类型的进化过程中进一步发展。
The root originated independently in euphyllophytes (ferns and seed plants) and lycophytes; however, the molecular evolutionary route of root initiation remains elusive. By analyses of the fern Ceratopteris richardii and seed plants, here we show that the molecular pathway involving auxin, intermediate-clade WUSCHEL-RELATED HOMEOBOX (IC-WOX) genes, and WUSCHEL-clade WOX (WC-WOX) genes could be conserved in root initiation. We propose that the "auxin>IC-WOX>WC-WOX" module in root initiation might have arisen in the common ancestor of euphyllophytes during the second origin of roots, and that this module has further developed during the evolution of different root types in ferns and seed plants.
