Root stem cells are crucial for the establishment of roots and are therefore a major evolutionary innovation that enabled land plants to spread on land. Despite their importance, not too much is known about the origin and the molecular players installing and maintaining them. Although still fragmentary, the recent availability of new data for early land plants can be used to identify and analyze the conservation of key regulators of root meristems. In this review, we evaluate the possible conservation of important root stem cell regulators to suggest pathways that might have been important at the origin of roots.

根干细胞的进化轨迹。

根干细胞对于根的建立至关重要，因此是一项重要的进化创新，使陆地植物得以在陆地上传播。尽管它们很重要，但是对于起源和安装和维护它们的分子参与者知之甚少。尽管仍然是零碎的，但最近可获得的早期陆地植物新数据可用于鉴定和分析根分生组织关键调节剂的保守性。在这篇综述中，我们评估了重要的根干细胞调节剂的可能保守性，以提出可能在根源方面可能很重要的途径。
