- Key message
- The suppressive function of OsSPY in GA signaling was supported by the findings that the dwarfism was partially rescued and OsGA20ox2 (GA20 oxidase) expression was reduced in GA-deficient and GA-insensitive mutants by the knockdown of OsSPY function
- Moreover, overexpression of SLRL1 in normal rice plants induced a dwarf phenotype with an increased level of OsGA20ox2 gene expression and diminished the GA-induced shoot elongation, suggesting that SLRL1 acts as a repressor of GA signaling
- Furthermore, OsGSR1 RNAi plants show a reduced sensitivity to GA treatment, an increased expression of the GA biosynthetic gene OsGA20ox2, which is feedback inhibited by GA signaling, and an elevated level of endogenous GA: together, these suggest that OsGSR1 is a positive regulator of GA signaling
- ), OsGA20ox2 ( SD1 ), is well known as the Green Revolution gene, and loss-of function mutation in this locus causes semi-dwarfism
- The short stature of IR8 is due to a mutation in the plant’s sd1 gene, and here we identify this gene as encoding an oxidase enzyme involved in the biosynthesis of gibberellin, a plant growth hormone
- The expression levels of gibberellin (GA) biosynthetic genes including OsCPS1, OsKS1, OsKO1, OsKAO, OsGA20ox2/SD1 and OsGA2ox3 were significantly increased in d62 mutant
- In this report, we show that a rice (Oryza sativa) YABBY1 (YAB1) gene had a similar expression pattern as key rice GA biosynthetic genes GA3ox2 and GA20ox2
- Control of grain protein contents through SEMIDWARF1 mutant alleles: sd1 increases the grain protein content in Dee-geo-woo-gen but not in Reimei.
- When submerged, plants carrying the deepwater rice-specific SD1 haplotype amplify a signaling relay in which the SD1 gene is transcriptionally activated by an ethylene-responsive transcription factor, OsEIL1a
- Here, we identify the gibberellin biosynthesis gene, SD1 (SEMIDWARF1), whose loss-of-function allele catapulted the rice Green Revolution, as being responsible for submergence-induced internode elongation
- Here, physical separation of two defects allows recombination to generate the wild-type SD1 gene, for which plant height can then be used as a reporter
- The loss of function of OsGA20ox2 and OsFBX267 in WP-22-2 resulted in reduced plant height as well as early flowering, and the same has been confirmed by editing OsGA20ox2 in the rice variety Pusa Basmati1 (PB1) using the CRISPR-Cas9 approach
- The targeted editing of OsGA20ox2 in PB1 conferred shorter plant height to the edited lines compared with the wild type
