Vliv faktorů vnějšího prostředí na vývoj průduchů v epidermis Arabidopsis thaliana - přenos signálu. / Influence of environmental factors on stomatal development in epidermis of Arabidopsis thaliana - signal trasduction.

The stomatal function and genetically based regulation of their number are interesting and important subjects of scientific research. Stomatal density on plant leaf surface is affected also by environmental factors, e.g. atmospheric CO2 concentration and irradiance (PAR). These two factors have common affect ? leaf internal CO2 concentration (Ci) in the leaf can be changed. The question might be if the Ci is the signal for expression of genes controlling stomatal development. According to the hypothesis which this thesis is based on I proposed an increase of expression of positive regulator STOMAGEN in the case when Ci is reduced. The expression of STOMAGEN was increased in plants with Ci decreased by higher PAR in contrast with plants where the Ci was decreased by adding of abscisic acid into nutrient solution. These results show no dependence of STOMAGEN expression on inner CO2 concentration.
