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.
- Association The spl38 mutant showed enhanced resistance to Xanthomonas oryzae pv. oryzae (Xoo).
- 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.
- Observation The spl38 mutant exhibited delayed flowering.
