Gene Details:

• Gene ID: HORVU.MOREX.r3.2HG0208900
• Gene Symbol: HvGA3ox1
• Gene Name: gibberellin 3-beta-dioxygenase
• Genome: MorexV3_pseudomolecules_assembly
• Species: Hordeum vulgare

Functional Descriptions:

• We revealed that CRISPR/Cas9-induced GA3ox1 mutations increased seed dormancy to an ideal level that could benefit the malting industry.
• We conclude that selecting HvGA3ox1 alleles offers a new opportunity for developing barley varieties with optimal stature, longer coleoptile and additional agronomic traits.
• Genetic variants within HvGA3ox1 were characterized to define and identify functional haplotypes associated with flowering time, plant height and grain yield components.
• CRISPR/Cas9-mediated knockout HvGA3ox1 increased the seed dormancy period but maintained the intrinsic germinative vigour.
