image: The rice XA21 receptor kinase, the first innate immune receptor discovered in plants or animals, provides resistance against Xanthomonas oryzae pv oryzae through recognition of RaxX, a tyrosine-sulfated protein secreted by the bacterium. This material relates to a paper that appeared in the July 24, 2015, issue of Science, published by AAAS. The paper, by R.N. Pruitt at University of California, Davis in Davis, Calif., and colleagues was titled, "The rice immune receptor XA21 recognizes a tyrosine-sulfated protein from a Gram-negative bacterium." view more
