Gene Symbol

• Os09g0369000 <=> OsDREB6,DREB6

Function

• OsDREB6 is an A-6 subgroup member of the DREB subfamily, encoding AP2/EREBP proteins.
• OsDREB6 may participate in the stress response by mediating the expression of specific genes, and may also be involved plant metabolism.
• OsDREB6 plays an important role in the response of plants to a wide range of osmotic stresses.

Phenotypic analysis

• Overexpression of OsDREB6 increased tolerance to osmotic, high salt, and cold stresses in transgenic rice whereas, OsDREB6 double-stranded RNA interference (RNAi) lines were found to be more sensitive to these stresses than wild- type rice.
• Additionally, sugar, proline and catalase levels in OsDREB6 RNAi lines were significantly lower than in the corresponding OsDREB6 overexpression lines and control lines after PEG treatment.
• In contrast, malondialdehyde (MDA) levels were significantly higher in RNAi lines than in control and overexpression lines. Furthermore, expression levels of some stress-related genes were altered in the transgenic plants.

Expression

• Expression pattern analysis indicated that OsDREB6 was induced in response to dehydration, high salinity, and most importantly by cold stress (4°C).
