Ovlivnění odpovědi rostlin na teplotní stres modulovanými hladinami cytokininů - fenomická a protemická analýza

Vícha, Daniel January 2015 (has links)
Cytokinins are important group of phytohormones regulating many physiological processes ranging from cell division to programmed cell death. This thesis is focused on effects of cytokinin levels in response to heat stress in Arabidopsis thaliana. Analysis of transgenic plants with regulated expression of ipt and HvCKX showed that cytokinins and their optimal levels play important role in the morphological alterations induced by heat stress. Seedlings with increased and decreased levels of cytokinins exhibit inhibition of petioles growth, decreased length of blades of true leaves and reduced leaf area. To obtain insights into molecular events underlying early response to heat stress LC-MS analysis of whole proteom was performed. Analysis revealed 57 differentialy regulated proteins in response to heat stress in Columbia ecotype. On the cellular level, most of the proteins were located in cytosol (47 %) nebo plastids (32 %). Coparative analysis between wild-type seedlings and seedlings with decreased level of cytokinins confirmed 31 proteinInfluencing plant responses to temperature stress modulating cytokinin levels - fenomic and proteomic analysiss regulated by cytokinins in response to heat stress. Among these proteins, desarurase 7 and Tudor SN1 protein were previously found as important factors in response to heat stress.
