Název v původním jazyce

Cyclic monoterpene mediated modulations of Arabidopsis thaliana phenotype: Effects on the cytoskeleton and on the expression of selected genes

Popis výsledku v původním jazyce

In this study, we show that monoterpens block stomatal closure which is accompanied by changes in the cytoskeleton having a direct role in stomatal movements. Although MPK3 (MAP3 kinase) and ABF4 gene expressions are induced within six hours, stomatal closure is prevented. In contrast to ABF4, ABF2 (both transcription factors) is not induced. MPK3 and ABF4 both encode for proteins involved in the process of stomatal closure. The expression of PEPCase, an enzyme important for stomatal opening, is down-regulated. It is proposed that high concentrations or repeated exposure to monoterpenes led to irreversible damages, whereas low concentrations or short-term fumigations may have the potential to strengthen the plant fitness.
