2022年9月13日 · Here, we demonstrate that miR160a positively regulates broad-spectrum resistance against the causative agents of blast, leaf blight and sheath blight in rice.

2023年2月6日 · In this study, we identified osa-miR172d-5p, a plant-derived microRNA (miR), as a potent anti-fibrotic miR. In silico analysis followed by an in vitro assay based on human lung fibroblasts...

Many rice microRNAs have been identified as fine-tuning factors in the regulation of agronomic traits and immunity. Among them, Osa-miR535 targets SQUAMOSA promoter binding protein-like 14 (OsSPL14) to positively regulate tillers but negatively regulate yield and immunity.

We identified rice defense-related miRNAs by comparing rice miRNA expression patterns before and after Magnaporthe oryzae strain Guy11 infection. We discovered that osa-miR164a expression reduced upon Guy11 infection at both early and late stages, which was perfectly associated with the induced expression of its target gene, OsNAC60.

Osa-miR535的过度表达显著降低了融合蛋白SPL4TB-YFP的积累，该融合蛋白包含OsSPL4中Osa-miR535的靶位点。 一致地，Osa-miR535在3'非翻译区预测结合位点的第10和第11碱基对之间介导OsSPL4 mRNA的切割。 过度表达OsSPL4（OXSP4）的转基因水稻表现出增强的稻瘟病抗性，同时增强了免疫应答，包括增加防御相关基因的表达和增加H2O2的积累。 相反，敲除突变体osspl4表现出易感性。 SPL基因编码一类植物特异性转录因子，在拟南芥和水稻的发育和免疫 …

2020年10月1日 · Results: RT-qPCR analysis suggested four subgroups of candidate miRNAs based on the time of their responses to the pathogenesis of R. solani. While Osa-miR-156 was early-responsive, Osa-miR159 was the last-responsive and Osa-miR167, Osa-miR171, Osa-miR408, and Osa-miR444 were late responsive to R. solani infection.

In this study, we identified osa-miR172d-5p, a plant-derived microRNA (miR), as a potent anti-fibrotic miR. In silico analysis followed by an in vitro assay based on human lung fibroblasts demonstrated that osa-miR172d-5p suppressed the gene expression of TGF-β activated kinase 1 (MAP3K7) binding protein 1 (Tab1).
