This work investigates the molecular mode of cytokinin action, based on the cytokinin-dependent accumulation of the red pigment amaranthin in etiolated and derooted seedlings of Amaranthus caudatus. We established a rapid 8 h test that permitted a quantitative and kinetic analysis of early cytokinin effects. Studies on the inhibitory effects of actinomycin(More)
A methodology is developed for revealing and identifying genetically modified sources (GMSs) in plant raw material and food products obtained from it, which enables routine analyses. For optimization suitable for testing DNA, three methods of isolating it are compared: CTAB method, DNA-BioPro method with Wizard columns, and Silica M method with specific(More)
Phytohormones, auxins in particular, play an important role in plant development and productivity. Earlier data showed positive impact of exogenous auxin on potato (Solanum tuberosum L.) tuberization. The aim of this study was to generate potato plants with increased auxin level predominantly in tubers. To this end, a pBinB33-tms1 vector was constructed(More)
The suggested link between intracellular cytokinin signaling and phospholipase D (PLD, EC 3.1.4.4.) activity (Romanov et al. 2000, 2002) was investigated. The activity of PLD in the early period of cytokinin action was studied in vivo in derooted Amaranthus caudatus seedlings, using the level of phosphatidylbutanol production as a measure of PLD activity.(More)
Ectopic auxin overproduction in transgenic potato leads to enhanced productivity accompanied with concerted and occasional changes in hormonal status, and causing altered response of transformants to exogenous auxin or cytokinin. Previously, we generated potato transformants expressing Agrobacterium-derived auxin synthesis gene tms1 driven by tuber-specific(More)
The tpd1 (from tobacco pollen development 1) insertion mutant of tobacco (Nicotiana tabacum L., cv. Samsun) with extended flowering period was investigated in detail in the course of plant development, and the inheritance of the mutant phenotype was established. The wild-type and mutant plants did not differ in basic developmental indices until the floral(More)
A method of multiplex polymerase chain reaction (PCR) followed by hybridization on a hydrogel oligonucleotide biochip was developed for simultaneous identification of ten different transgenic elements of plant DNA in food and feed products. The biochip contained 22 immobilized oligonucleotide probes that were intended for (1) detection of plant DNA, (2)(More)
