Tuber induction in spontaneously tuberizing potato line: the role of saccharides and mobile transcripts
 Stupecká, Lenka ; Mašková, Petra (advisor) ; Fischer, Lukáš (referee)
Potato is one of the most important agricultural crops and there is an attempt to increase and improve yields of tubers, among other things, by elucidation of the mechanisms that regulate the process of tuber induction. Potato tuberization is a morphogenetic process in which the tubers are formed from the underground parts of the stem - stolons. The correct timing of this process is controlled by a complex regulatory network and influenced by many internal and external factors. Under favourable conditions, an inductive signal is generated in the leaves and it is transported to the stolon by a "phloem information superhighway" driven by carbohydrates flow. The signal triggers cell division, expansion, and changes in the cell growth orientation in the stolon. The development of tubers is influenced by number of biochemical and morphological processes driven by a regulatory network of genes that are expressed in different parts of plants. This work was focused on Solanum tuberosum, Lada cultivar and its derived D69 mutant line with lacking isoform of manganese-stabilizing protein (MSP), which is so far the only dissimilarity identified under all tested conditions. I aimed to map the processes related to the production of carbohydrates in leaves (photosynthetic characteristics - rate of photosynthesis...
