| Title | <i>LG5</i>, a Novel Allele of <i>EUI1</i>, Regulates grain size and flag leaf Angle in Rice. | |
|
Abstract: grain size and flag leaf angle are two important traits that determining grain yield in rice. However, the mechanisms regulating these two traits remain largely unknown. In this study, a rice <i>long grain 5</i> (<i>lg5</i>) mutant with a large flag leaf angle was identified, and map-based cloning revealed that a single base substitution followed by a 2 bp insertion in the <i>LOC_Os05g40384</i> gene resulted in larger grains, a larger flag leaf angle, and higher plant height than the wild type. Sequence analysis revealed that <i>lg5</i> is a novel allele of <i>elongated uppermost internode-1</i> (<i>EUI1</i>), which encodes a cytochrome P450 protein. Functional complementation and overexpression tests showed that <i>LG5</i> can rescue the bigger grain size and larger flag leaf angle in the Xiushui11 (XS) background. Knockdown of the <i>LG5</i> transcription level by RNA interference resulted in elevated grain size and flag leaf angle in the Nipponbare (NIP) background. Morphological and cellular analyses suggested that <i>LG5</i> regulated grain size and flag leaf angle by promoting cell expansion and cell proliferation. Our results provided new insight into the functions of <i>EUI1</i> in rice, especially in regulating grain size and flag leaf angle, indicating a potential target for the improvement of rice breeding. |
