Molecular analysis of plant genes involved in the maintenance of cell fate

维持干细胞的未分化状态和分化细胞的细胞命运对植物的生长发育至关重要。我们发现了一个通过减少DNA损伤来维持干细胞未分化状态所需的新基因。我们还发现，已知的基因在细胞分化过程中具有新的功能。因此，这些结果为维持植物细胞命运提供了新的机制。

It is essential for plant growth and development to maintain the undifferentiated state of stem cells and the cell fate of differentiating cells. We identified a novel gene required for maintenance of undifferentiated state of stem cells through the reduction of DNA damage. We also found that the known gene has a novel function for proper progression of cell differentiation process. These results, thus, suggested novel mechanisms for the maintenance of plant cell fate.
