TAILIEUCHUNG - Salt-inducible expression of OsJAZ8 improves resilience against salt-stress

Productivity of important crop rice is greatly affected by salinity. The plant hormone jasmonate plays a vital role in salt stress adaptation, but also evokes detrimental side effects if not timely shut down again. | Salt-inducible expression of OsJAZ8 improves resilience against salt-stress .den color inherit .ttnd ol .ttnd ul .ttnd dl padding 0 0px 0 20px .ttnd hr margin 10px 0px .ttnd a href javascript void 0 .ttnd a href color inherit dtextscript p text-align left dtextscript img vertical-align middle Peethambaran et al.

The plant hormone jasmonate plays lt br gt a vital role in salt stress adaptation but also evokes detrimental side effects if not timely shut down again. As novel lt br gt strategy to avoid such side effects OsJAZ8 a negative regulator of jasmonate signalling is expressed under control lt br gt of the salt-inducible promoter of the transcription factor ZOS3 11 to obtain a transient jasmonate signature in lt br gt response to salt stress. To modulate the time course of jasmonate signalling either a full-length or a dominant lt br gt negative C-terminally truncated version of OsJAZ8 driven by the ZOS3 11 promoter were expressed in a stable lt br gt manner either in tobacco BY-2 cells or in japonica rice. lt br gt Results The transgenic tobacco cells showed reduced mortality and efficient cycling under salt stress adaptation. lt br gt This was accompanied by reduced sensitivity to Methyl jasmonate and increased responsiveness to auxin. In the lt br gt case of transgenic rice the steady-state levels of OsJAZ8 transcripts were more efficiently induced under salt
