Function
OsGAI, also known as slender rice 1(SLR1), is first identified as a homolog of the GAI gene of Arabidopsis (Ogawa, et al. 2000). It encodes a rice DELLA protein of 625 amino acids, which is characterized as a member of the GRAS family. Sequences analyses reveal that SLR1 contains a valine (polyS/T/V), a DELLA box, a TVHYNP region, a nuclear localization signal (NLS), a leucine heptad repeat (LZ) and the VHIID motif in N-terminal and the PFYRE motif and the SAW motif in C-terminal (Itoh 2002). In addition, function domain analyses reveal that the SLR1 protein can be divided into four parts: a regulatory domain for its repression activity, a dimer formation domain essential for signal perception and repression activity, and a repression domain at the C terminus, a GA signal perception domain located at the N terminus. Gibberellin (GA), a key phytohormone, controls many crucial aspects during the whole life cycle of plants, including germination, stem elongation, flower development and stress response. The study of mutant indicates that SLR1 is a negative regulator in GA signaling pathway, and overexpressing SLR1 gene in transgenic rice plants cause dwarf phenotype (Itoh 2002). DELLA protein SLR1 represses the GA-response gene expression by direct binding to transcription factor of target gene. Application of exogenous GA causes disappearance of SLR1-GFP in nuclei.
Expression
Genomic DNA blot analysis indicates the OsGAI is a single-copy gene in the rice genome. OsGAI transcripts increased within 6h upon GA3. The subcellular localization of OsGAI in vivo shows that OsGAI-GFP fusion protein locates in the nucleus concerned with a nuclear localization signal (NLS).
Evolution
The SLR1 protein shares a high overall identity with RHT-D1a in wheat (77.2%), D8 in maize (80.3%), and RGA and GAI in Arabidopsis (41.2 and 47.2%, respectively)
