Gene Details:

• MSU gene ID: LOC_Os02g10760
• RAPdb gene ID: Os02g0202000
• Gene Symbol: OsWR1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• An ethylene response factor OsWR1 responsive to drought stress transcriptionally activates wax synthesis related genes and increases wax production in rice.
• In addition, OsWR1 activated the expression of the genes-related to oxidative stress response and membrane stability.
• Functional analyses indicated that overexpressing OsWR1 (Ox-WR1) improved while RNA interference OsWR1 rice (RI-WR1) decreased drought tolerance, consistent with water loss and cuticular permeability, suggesting that OsWR1-triggered drought response might be associated with cuticular characteristics.
• Thus our results indicate that OsWR1 is a positive regulator of wax synthesis related genes in rice, and this regulation, distinct from its homology regulator of WIN1/SHN1 in cutin synthesis, subsequently contributes to reduced water loss and enhanced drought tolerance.
• Transcript analysis showed that OsWR1 is induced by drought, abscisic acid and salt, and is predominantly expressed in leaves.
• This rice wax synthesis regulatory gene 1 (OsWR1) is a homolog of Arabidopsis wax/cutin synthesis regulatory gene WIN1/SHN1.
