- Genbank accession number
- Key message
- We have cloned two gibberellin (GA) 3 beta-hydroxylase genes, OsGA3ox1 and OsGA3ox2, from rice by screening a genomic library with a DNA fragment obtained by PCR using degenerate primers
- Although both genes show transient expression, the highest level for OsGA3ox1 is from unopened flower
- In addition, we generate an osga3ox1 knockout mutant by genome editing and demonstrate the bioactive gibberellic acid synthesis by the OsGA3ox1 action during starch accumulation in pollen via invertase regulation
- Connection
- OsGA2ox1, OsGA3ox1, Gibberellin homeostasis and plant height control by EUI and a role for gibberellin in root gravity responses in rice, In addition, the GA biosynthesis genes GA3ox1 and GA20ox2 were downregulated and GA2ox1 was upregulated in eui seedlings
- d18~OsGA3ox2, OsGA3ox1, Cloning and functional analysis of two gibberellin 3 beta -hydroxylase genes that are differently expressed during the growth of rice, Molecular and linkage analysis maps the OsGA3ox1 gene to the distal end of the short arm of chromosome 5; the OsGA3ox2 gene maps to the distal end of the short arm of chromosome 1 that corresponds to the D18 locus
- d18~OsGA3ox2, OsGA3ox1, Cloning and functional analysis of two gibberellin 3 beta -hydroxylase genes that are differently expressed during the growth of rice, We have cloned two gibberellin (GA) 3 beta-hydroxylase genes, OsGA3ox1 and OsGA3ox2, from rice by screening a genomic library with a DNA fragment obtained by PCR using degenerate primers
- d18~OsGA3ox2, OsGA3ox1, Evolutionary alterations in gene expression and enzymatic activities of gibberellin 3-oxidase 1 in Oryza., Enzymatic and X-ray crystallography analyses reveal that OsGA3ox1 has a higher GA(7) synthesis ratio than OsGA3ox2
