The process offlowering is controlled by external factors such as light and temperature.Floral induction is the first step in the transition from the vegetative to reproductive stage of development. In the photoperiodically sensitive plants this process is regulated by the duration of light and darkness during a 24-h cycle. Theaim of our study was to determine whether the undifferentiated callus tissueobtained from cotyledons, is suitable for molecular investigations on the mechanisms of flower induction. The callus tissue was obtained from cotyledons ofPharbitis nil plants, which were cultivated in inductive or non-inductive conditions. The callus obtained after two subcultures was used for isolation of RNA.The total RNA was extracted as described by Chomczynski (1993). We have examined the changes in the pattern of RNA in these two types of callus, using thetechnique of differential display by the polymerase chain reaction (PCR). Differential display is a method for the identification and cloning of differentiallyexpressed eucaryotic genes.}, title={Application of callus tissue in the studies on molecular mechanism offlower induction}, type={Text}, URL={http://rcin.org.pl/Content/139325/PDF/POZN271_174725_biotechnologia-2001-no2-szyp.pdf}, keywords={biotechnology}, }
