RLINl,encoding a putative coproporphyrinogen Ⅲ oxidase,is involved in lesion initiation in rice被引量:35
2011年
Lesion mimic is necrotic lesions on plant leaf or stem in the absence of pathogenic infection, and its exact biological mechanism is varied. By a large-scale screening of our T-DNA mutant population, we identified a mutant rice lesion initiation 1 (rlin1), which was controlled by a single nuclear recessive gene. Map-based cloning revealed that RLIN1 encoded a putative coproporphyrinogen Ⅲ oxidase in tetrapyrrole biosynthesis pathway. Sequencing results showed that a G to T substitution occurred in the second exon of RLIN1 and led to a missense mutation from Asp to Tyr. Ectopic expression of RLIN1 could rescue rlin1 lesion mimic phenotype. Histochemical analysis demonstrated that lesion formation in rlin1 was light-dependent accompanied by reactive oxygen species accumulated. These results suggest that tetrapyrrole participates in lesion formation in rice.
