Species Oryza sativa (Rice) [ GR_tax:013681 ]
Accession GR:0060897
Gene Symbol SLR
Gene Name SLENDER RICE 
Synonyms (7)
E.C. Numbers (0)
Pathway Reactions (0)
Chromosome No. 3
Gene Type CDS (Protein coding)
Has Phenotype yes
Description The slender mutant results in a constitutive gibberellin (GA) response phenoype, including slender shoots, basal internodes elongate, reduced root number and root length, increased cell length at the apical portion of the second leaf sheath. The SLR1 gene is an intermediate of the GA signal transduction pathway. SLR1 maps to OsGAI in rice and has significant homology with height-regulating genes, such as RHT-1Da in wheat, D8 in maize (GR:0200107), and GAI and RGA in Arabidopsis. The GAI gene family is likely to encode transcriptional factors belonging to the GRAS gene superfamily. DNA sequence analysis revealed that the slr1-1 mutation is a single basepair deletion of the nuclear localization signal domain, resulting in a frameshift mutation that abolishes protein production.
