e1“Here, we identified a rice (Oryza sativa) LMM, spotted leaf 38 (spl38), and demonstrated that spl38 is essential for the formation of hypersensitive response-like lesions and innate immunity”
e3“The spl38 mutant showed enhanced resistance to rice pathogens Magnaporthe oryzae and Xanthomonas oryzae pv. oryzae (Xoo) and exhibited delayed flowering”

Other claims from this paper (14)
- Mechanism The spl38 mutant is essential for hypersensitive response-like lesions and innate immunity.
- Observation SPL38 encodes MEDIATOR SUBUNIT 16 (OsMED16).
- Association The spl38 mutant showed enhanced resistance to Magnaporthe oryzae.
- Intervention effect OsMED16-overexpressing plants showed increased susceptibility to Magnaporthe oryzae.
- Observation OsMED16-edited rice lines were phenotypically similar to the spl38 mutant.
- Intervention effect OsMED16-edited rice lines showed growth retardation and were extremely weak.
- Observation OsMED16-edited rice lines eventually died.
- Intervention effect The ospr3 osmed16 double mutants did not exhibit the lesion mimic phenotype of the spl38 mutant.
- Observation The C-terminus of OsMED16 interacts with OsPR3.
- Mechanism OsMED16 competitively represses the chitinase and chitin-binding activities of OsPR3.
- Association OsMED16 has an opposite function in plant defense relative to Arabidopsis AtMED16.
- Mechanism The opposite defense function of OsMED16 is most likely due to two amino acid substitutions between monocot and dicot MED16s.
- Mechanism OsMED16 negatively regulates cell death and immunity in rice, probably via the OsPR3-mediated chitin signaling pathway.
- Observation The spl38 mutant exhibited delayed flowering.
