Význam glutathionu v hormonální regulaci odpovědi na stres u Arabidopsis thaliana
 Šlapáková, Martina
Tripeptide glutathione plays a key role in combating stresses such as heavy metal or xenobi-otic exposure. Recent studies have shown that glutathione content is negatively modulated by cytokinin. Thus, glutathione may be intimately involved in enhanced stress tolerance displayed in cytokinin-deficient plants. To probe the physiological relevance of the crosstalk between cytokinin and glutathione, a response to a glutahione-depleting xenobiotic 1-chloro-2,4-dinitrobenzene (CDNB) was analysed in the model plant Arabidopsis thaliana. Here we show that CDNB causes decrease of cytokinin status. We found that transgenic plants with reduced endogenous cytokinin levels showed a CDNB-tolerant phenotype. Cy-tokinin depletion provoked the accumulation glutathione. Glutathione-deficiency abolishes CDNB tolerance of cytokinin-deficient plants supporting an essencial role of glutathione for CDNB sequestration. Our findings indicate that cytokinin is an important regulatory factor in plant adaptation to CDNB stress.
