Analysis of abiotic stress induced genes in rape
 HOŠTIČKOVÁ, Irena
Breeding for abiotic stress tolerance is one of main topics in plant breeding. Oilseed rape breeding programs were for a long time focused on morphological and physiological parameters. In this thesis few experiments focused on identification of genes involved in abiotic stress reaction were performed using RT-qPCR (quantitative reverse transcription PCR). Simultaneously SPR (surface plasmon resonance) method were used as modern optical method facilitating very low native protein concentration even in presence of other substances. This method facilitates quantification of concrete proteins by binding them to specific antigen and in oilseed rape research it was not used by now. ERD10 protein was identified by SPR as protein involved in cold stress reaction (or acclimation). The results show ERD10 accumulation in standard conditions affects dynamics of its accumulation change during cold stress. In case we are searching for genotypes great in acclimation ability even during short and warm autumn SPR method should be suitable method for fast, easy and relatively cheap screening of large number of genotypes in breeding collections. Also genes LTI78, RCI2A, NRP1 and two genes for hypothetical proteins were analysed. Their relative expression during cold stress was markedly increased too. Very little is known about these genes and proteins nowadays therefor it will be interesting topic of our oncoming experiment. Relative expression of genes picked according to MALDI-TOF/TOF analysis results was also tested in microspore embryo regenerants stressed by simulated drought. Genes for lactoylglutathione lyase I, phospholipase D 1 and peroxiredoxin antioxidase were tested. In tolerant cultivar was markedly decreased gene expression of peroxiredoxin antioxidase in standard conditions and early stress. These gene will be subject for next research as potential marker for more tolerant genotypes selection.
