Summary:
The Xa1 gene induces resistance to all or nearly all TAL effectors in certain crops thus providing with a new approach to combat most crop diseases induced by Xanthomonas.

Development Stage:

Description:
By unmasking the suppressive function of bacterial pseudogenes, the researchers discovered hat Xa1, an NBS-LRR type disease resistance gene in rice, can recognize all test TAL effector genes and confer disease resistance to those pathogenic bacteria that contain such TALE effector genes. Several crop diseases, such as wheat blight, citrus canker, cotton blight, etc. are caused by Xanthomonas bacteria that harbor multiple copies of TAL effector genes but not suppressor pseudogene. Therefore, Xa1 and its derivatives can be used as broad spectrum disease-resistance genes.

Advantage:
• Native rice gene.
• Wheat plants available for evaluation.
• Predicted broad resistance to Xanthomonas in most plants.
