Contents
Annotated Information
Gene Symbol
- Os06g0226500 <=> ILI4, OsBU1
Function
- Brassinosteroids (BRs) are involved in many developmental processes and regulate many subsets of downstream genes throughout the plant kingdom.
- The rice BRASSINOSTEROID UPREGULATED1 (BU1) is a novel BR-induced gene encoding a helix-loop-helix protein.
- BU1 protein is a positive regulator of BR response: it controls bending of the lamina joint in rice and it is a novel primary response gene that participates in two BR signaling pathways through OsBRI1 and RGA1.
- BU1 may participate in some other unknown processes modulated by BR in rice.
Phenotypic analysis
- Rice plants overexpressing BU1(BU1:OX) showed enhanced bending of the lamina joint, increased grain size, and resistance to brassinazole, an inhibitor of BR biosynthesis.
- In contrast to BU1:OX, RNAi plants designed to repress both BU1 and its homologs displayed erect leaves.
- In addition, compared to the wild type, the induction of BU1 by exogenous brassinolide did not require de novo protein synthesis and it was weaker in a BR receptor mutant OsbriI (Oryza sativa brassinosteroid insensitive1, d61) and a rice G protein alpha subunit (RGA1) mutant d1.
Expression
- Expression analyses showed that BU1 is expressed in several organs including lamina joint, phloem, and epithelial cells in embryos.
