Protein
TAL effector protein PthXo1
Organism
Xanthomonas oryzae pv. oryzae (strain PXO99A)
Function
Avirulence protein. Acts as a transcription factor in rice, inducing expression of a number of host genes including SWEET11 (Os8N3, XA13, AC Q6YZF3) in susceptible plants with the Xa13 allele. Plants with the xa13 allele, which has an altered promoter, are resistant to bacterial blight caused by this bacterial strain and do not induce SWEET11. The xa13 allele elicits an atypical hypersensitive response (HR). PthXo1 binds SWEET11 promoter DNA in a sequence-specific manner.
Similarity
Belongs to the transcription activator-like effector (TALE) family.
