- Key message
- Our data showed that rice LRK1 is a plasma membrane protein expressed constitutively in leaves, young panicles, roots and culms
- The over-expression of rice LRK1 results in increased panicles, spikelets per panicle, weight per grain and enhanced cellular proliferation, leading to a 27
- The functional characterization of rice LRK1 facilitates an understanding of the mechanisms involved in cereal crop yield, and may have utility in improving grain yield in cereal crops
- Over-expression of the rice LRK1 gene improves quantitative yield components
- Analyses of gene expression demonstrated that LRK1 restricts gibberellin biosynthesis during the internode elongation process by down-regulation of the gibberellin biosynthetic gene coding for ent-kaurene oxidase
- Our data suggest that rice LRK1 regulates rice branch number by enhancing cellular proliferation
- This study demonstrates a substantial natural variation of Rd in rice and that the LRK1 gene can regulate leaf dark respiratory fluxes, especially under high temperature
- A rice lrk1 mutant shows only ~37% Rd of that of WT and retarded growth following exposure to 35
C for 30 days, but only 24% reduction in growth was recorded under normal temperature (25 C) - Particularly, we observed that the LRK1 gene, annotated as leucine rich repeat receptor kinase, was up-regulated four times
- Connection
- LRK1, OsWDR5a~OsWDR5, Overexpressing lncRNA LAIR increases grain yield and regulates neighbouring gene cluster expression in rice., LAIR binds histone modification proteins OsMOF and OsWDR5 in rice cells, which are enriched in LRK1 gene region
- LRK1, OsHAM701~OsMOF, Overexpressing lncRNA LAIR increases grain yield and regulates neighbouring gene cluster expression in rice., LAIR binds histone modification proteins OsMOF and OsWDR5 in rice cells, which are enriched in LRK1 gene region
- LAIR, LRK1, Overexpressing lncRNA LAIR increases grain yield and regulates neighbouring gene cluster expression in rice., LAIR binds histone modification proteins OsMOF and OsWDR5 in rice cells, which are enriched in LRK1 gene region
- LAIR, LRK1, Overexpressing lncRNA LAIR increases grain yield and regulates neighbouring gene cluster expression in rice., Moreover, LAIR is demonstrated to bind 5’ and 3’ untranslated regions of LRK1 gene
