Annotated Information
Function
ERF proteins, Arabidopsis WIN1/SHN1 and Medicago WXP1/2, have been shown to induce the production of epidermal waxes when overexpressed in plants.
The WIN1-like OsWR1 controls wax formation by direct or collaborative activation of wax synthesis genes, and this regulation, distinct from its homology regulator of WIN1/SHN1 in cutin synthesis, subsequently results in reduced water loss and enhanced drought tolerance.
To investigate the functional role of this region,Youhua Wang fused the coding regions of OsWR1 and its deletion of the predicted acidic activation region to the DNA-binding-domain expres- sion vector of GAL4 and examined the behavior of GAL4– OsWR1 and GAL4–OsWR1–DAD constructs as potential transcriptional activators in yeast. In the presence of the activation domain, the OsWR1 protein fused to the DNA- binding domain activated transcription of the lacZ reporter gene, whereas GAL4–OsWR1–DAD could not, indicating that the OsWR1 protein may act as a transcriptional activator.
Datas reveal that OsWR1 is responsive to drought, salt and ABA in rice.
OsWR1 is a positive regulator for drought response through affecting water loss.
Expression
Nuclear localization
To test nuclear localization, an in vivo targeting experiment was performed by fusing the coding region of OsWR1 to GFP, and the resulting constructs (WR1–GFP and GFP only) were introduced into rice calli by agroinfiltration. These fusion proteins, under the control of the CaMV 35S promoter, were expressed in rice callus cells,and the localization of the fusion protein was determined by visualization with a fluorescence microscope. The result indicates that WR1–GFP was localized primarily in the nucleus, while GFP-only was observed in cytosol.
