Bacterial Protein Activates Rice Immune System
July 29, 2015| |
Rice's immune responses against bacterial blight have been studied by a team of researchers led by University of California Professor Pamela Ronald. Bacterial blight is caused by Xanthomonas oryzae pv oryzae (Xoo), which causes great losses in crops. In the study, the researchers were able to identify a bacterial protein responsible for the activation of defensive response of rice plants towards Xoo.
The researchers discovered that a tyrosine-sulfated bacterial protein, RaxX is the one responsible for the activation of rice receptor protein, XA21. The activation of this receptor triggers the immune response of rice against Xoo.
This discovery will help in the future developments of resistant crop varieties.
Full details of the study can be read at Lawrence Berkeley National Laboratory website.
