Abstract

We will use an array of transgenic tobacco lines for an appraisal of newly proposed protective signalling mechanisms in plants under environmental stress, primarily heat but also cold. Marker transgenes driven by promoters inducible by salicylic acid and H2O2 will be used to examine tissue locations and environmental responses of these compounds. The role of salicylic acid in stress tolerance and acclimation will be assessed using the salicylate- degrading SH-L transgene driven by constitutive, heat-shock, H2O2-inducible or salicylate- inducible promoters. Most of these transgenic lines have been made in previous BBSRC research. We will also clone and make an antisense-transgene from a gp91-phox homologue expressed in heat-stressed tobacco, to evaluate the source and role of abiotic- stress H2O2.
