OsEIL1 mRNA Poly(A) Tail Processing Factor CPR5

Phospho-regulated blast resistance

Receptor kinase FLR2 phosphorylates CPR5 to fine-tune poly(A) tail length of the immune regulator OsEIL1, thereby enhancing rice resistance against Magnaporthe oryzae.

Advantages

cpr5 mutant showed increased resistance to M. oryzae

cpr5 mutant induced reactive oxygen species generation

cpr5 mutant activated the MAPK cascade

Phospho-dead cpr5mut5A resulted in longer poly(A) tail length of OsEIL1 than wild type
