Gene Details:

• MSU gene ID: LOC_Os05g08540
• RAPdb gene ID: Os05g0178100
• Gene Symbol: OsGA3ox1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• 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.
