为了解开植物先天免疫中植物与细菌神秘联系之谜,目前,美国加利福尼亚大学戴维斯分校的科学家Pamela Ronald等鉴定了细菌的信号传递分子,它可与水稻植株体内的特异性受体配对阻挡毁灭性的的水稻白叶枯病。Ronald和他的同事们鉴定了一种定名为ax21的缩氨酸化合物,ax21是与XA21受体蛋白绑定的分子。这种绑定触发了对细菌性病害的防御反应。研究人员指出,在黄单胞菌和苛养木杆菌Xylella In order to solve the mystery of the mysterious relationship between plants and bacteria in plant innate immunity, scientists such as Pamela Ronald at the University of California, Davis, identified the signal transduction molecule of bacteria that can block the specific receptors in rice plants Destructive rice bacterial blight. Ronald and colleagues identified a peptide known as ax21, an ax21 molecule that binds to the XA21 receptor protein. This binding triggers a defensive response to bacterial diseases. The researchers pointed out that in Xylella Xanthomonas and Xylella
