SEMI‐ROLLED LEAF 10 stabilizes catalase isozyme B to regulate leaf morphology and thermotolerance in rice (Oryza sativa L.)

Rice raising is a complex process that involves plant architecture and stress tolerance. Both abiotic stress resistance and rice grain yield can be enhanced by specific leaf morphologies and excellent plant architecture. However, the mechanism by which plants simultaneously control leaf growth and stress resistance is unclear. SRL10, which encodes a double-stranded RNA binding protein, regulates leaf morphology and thermotolerance in rice by altering microRNA biogenesis, according to this article. Both the field and the growth chamber were found to have the natural Hap3 allele, which was discovered in the majority of aus rice accessions and classified as a thermotolerant allele under extreme temperature stress. Moreover, the seedu2010setting rates were 3. 19 times higher and grain yield per plant was 1. 68 times higher in near-u2010isogenic line carrying Hap3 alleles, compared to plants carrying Hap1 allele under heat stress.

The catalase‐peroxidase PiCP1 plays a critical role in abiotic stress resistance, pathogenicity and asexual structure development in Phytophthora infestans

PiCP1u2010silenced transformants had decreased catalase activity, reduced oxidant stress resistance, and damped cell wall integrity when compared to the wild type. Callose deposition in plant tissue can also be induced by PiCP1's high concentration. Both STs and OTs have drastically reduced sporangia formation and zoospore releasing rate, although sporangia proliferation and zoospore production rate was reduced, but sporangia germination rate and type varied depending on environmental conditions. Catalase—u2013peroxidases are widely distributed and highly conserved among soil-u2013borne plant parasitic oomycetes, but not in freshwateru2010inhabiting or strictly plantsu2010inhabiting oomycetes, according to a survey by comparative sequence analyses.
