ID 14748
Name slr (GENE SYMBOL)
Synonyms (2)
GRAMENE GENEGR:0060897
Type Gene
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
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.
