RESULTS: The numbers of individuals (adults, immature stages, and eggs) were significantly lower in OSM1-OE lines than those in wild-type (WT) plants. On the other hand, the osm1-ko lines showed larger numbers of mites per leaf than WT plants. When plants reached the full maturity stage, two out of the three infested OSM1-OE lines presented lower plant height than WT, while the three osm1-ko lines (infested or not) presented higher plant height than WT. The reduction in seed number caused by mite infestation was lower in OSM1-OE lines (12-19%) than in WT plants (34%), while osm1-ko lines presented higher reduction (24-54%) in seed number than WT plants (13%).
CONCLUSIONS: These data suggest that Osmotin1 is involved in rice resistance to S. oryzae infestation. This is the first work showing increased plant resistance to herbivory overexpressing an Osmotin gene. © 2023 Society of Chemical Industry.
结果:个体数量(成人,不成熟的阶段,和卵)在OSM1-OE品系中显着低于野生型(WT)植物。另一方面,osm1-ko系的每叶螨虫数量比WT植物多。当植物达到完全成熟阶段时,三个受侵染的OSM1-OE系中有两个比WT高,而三个osm1-ko系(受感染或未感染)的株高高于WT。OSM1-OE系(12-19%)的螨侵染引起的种子数量减少低于WT植物(34%),而osM1-ko系的种子数量减少(24-54%)比WT植物(13%)更多。
结论:这些数据表明Osmotin1参与了水稻对米曲霉侵染的抗性。这是第一项工作,表明植物对草食性过表达Osmotin基因的抗性增加。本文受版权保护。保留所有权利。
