Gene Details:

• Gene ID: MLOC_7938.1
• Gene Symbol: HvOle3
• Gene Name: oleosin 3
• Genome: MorexV3_pseudomolecules_assembly
• Species: Hordeum vulgare

Functional Descriptions:

• Abscisic acid activation of oleosin gene HvOle3 expression prevents the coalescence of protein storage vacuoles in barley aleurone cells.
• Gain-of-function analyses revealed that HvOle3 effectively delayed PSV coalescence, whereas HvOLE1 only had a moderate effect, with no notable effect of HvOLE2 and 4.
• Experiments swapping the N- and C-terminal domain between HvOle3 and other HvOLEs showed that the N-terminal region of HvOle3 is mainly responsible, with some positive effect by the C-terminal region, for mediating the specific preventive effect of HvOle3 on PSV coalescence.
• Transient expression assays using aleurone protoplasts demonstrated that transcriptional activation of the HvOle3 promoter was mediated by transcription factors HvABI3 and HvABI5, which acted downstream of protein kinase HvPKABA1.
