A Novel Allele Encoding 7-Hydroxymethyl Chlorophyll a Reductase Confers Bacterial Blight Resistance in Rice.

Rice spotted leaf mutants are helpful to investigate programmed cell death (PCD) and defense response pathways in plants. Using a map-based cloning strategy, we characterized novel rice spotted leaf mutation that encodes a 7-hydroxymethyl chlorophyll a reductase (). The wild-type (WT) allele could rescue the mutant phenotype, as evidenced by complementation analysis.
