Cultured guard cell protoplasts (GCP) of Nicotiana glauca, tree tobacco, comprise a novel system for investigating the cell signaling mechanisms that lead to acquired thermotolerance and thermoinhibition. At 32 $^{circ}$ C in a medium containing an auxin and a cytokinin, GCP expand, regenerate cell walls, dedifferentiate, and divide. At 38 $^{circ}$ C, GCP acquire thermotolerance, but their expansion is limited and they neither regenerate walls nor re-enter the cell cycle. Protoplasts were transformed with the fusion gene of BA auxin-responsive promoter and green fluorescent protein (GFP) gene. Heat suppressed auxin-mediated activation of BA. Heat-stressed cells accumulate reactive oxygen species, and H $_{2}$ O $_{2}$ suppresses auxin-responsive promoter activation. H $_{2}$ O $_{2}$ did not suppress BA activation at 32 $^{circ}$ C, nor did superoxide and H $_{2}$ O $_{2}$ scavengers prevent BA suppression at 38 $^{circ}$ C.

At 32 $^{circ}$ C in media containing an auxin and a cytokinin, cultured guard cell protoplasts (GCP) of Nicotiana glauca (Graham), expand, regenerate cell walls, dedifferentiate, and divide. At 38 $^{circ}$ C, GCP acquire thermotolerance within 24 h but their expansion is limited and they neither regenerate walls nor re-enter the cell cycle. Protoplasts were transformed with BA-mgfp5-ER. After 21 h in media with NAA, 49.0% and 7.9% of GCP transformed with BA-mgfp5-ER expressed GFP at 32 $^{circ}$ C and 38 $^{circ}$ C, respectively. Expression at 38 $^{circ}$ C was not increased by incubating GCP for 48 h or by increasing NAA concentrations 20X. Tiron and N-acetylcysteine, superoxide and H $_{2}$ O $_{2}$ scavengers, respectively, did not prevent BA suppression at 38 $^{circ}$ C nor did H $_{2}$ O $_{2}$ suppress BA activation at 32 $^{circ}$ C.
