Local wound signaling in plants informs the surrounding tissues about an injury and initiates the regeneration process. In a recent paper published in Cell, Yang and colleagues show the involvement of a single Pep family member from tomato in wound signaling and how exogenous application of this regeneration factor enhances transformation efficiency in crops.

感受危险：植物中的局部伤口信号

植物中的局部伤口信号传导会告知周围组织损伤并启动再生过程。在最近发表在《细胞》上的一篇论文中，Yang 及其同事展示了番茄中单个 Pep 家族成员参与伤口信号传导，以及这种再生因子的外源应用如何提高作物的转化效率。
