Annotated Information

Function

Please input function information here.

WRKY genes are a family of transcriptional regulatory factors that have specific functions in plants.Plant WRKY gene-encoded transcriptional regulators appear to be involved in various physiological programs, including disease-resistance,senescence,stress responses of biotic and abiotic, growth and development processes. overexpression of the OsWRKY89 gene enhanced resistance to the rice blast fungus and white-backed planthopper as well as tolerance to UV-B irradiation. These results suggest that OsWRKY89 plays an important role in response to biotic and abiotic stresses.

Expression

Please input expression information here.

Expression of OsW89p::GUS was observed in leaves, stems, and sheaths; pollens hadn't expression; mature seeds hadn't expression; the embryos of germinating seeds had expression; primary roots, adventitious roots and their lateral roots had expression but not in root tips of seedling stage; only lateral roots had expressin in roots of maturation phase.

Analyzing inducible expression pattern in T1 transgenic seedlings, the results showed: expression level of OsW89p::GUS can be increased by MeJA, IAA, ultraviolet, high temperature, low temperature and wounding treatment, inducible effects of MeJA and ultraviolet were distinct; and can be restrined by 2, 4-D; ABA and SA can't influence OsW89p::GUS expession; NaCl and PEG can restrain expression level of OsW89p::GUS in roots but increase expression level in leaves.GUS activity of OsW89p::GUS was higher than 35s::GUS in trangenic plants.In conclusion,we thought OsWRKY89 gene promoter was an inducible promoter with tissue specific expression characteristic.

WRKY genes encode transcription factors that are involved in the regulation of various biological processes. These zinc-finger proteins, especially those members mediating stress responses, are uniquely expanded in plants.
