The role of phytohormones in genetic tumor formation on radish crop-roots was investigated using the collection of inbred Raphanus sativus lines as a model system. The genetic analysis showed that the trait <<tumor formation>> was recessive and monogenic in some crossings. The spectrum of main phytohormones in tumor and non-tumor radish lines has shown that(More)
CLE (CLAVATA3/ENDOSPERM SURROUNDING REGION) peptides are peptide phytohormones playing the important role in the regulation of various type meristem development and also in the interaction between plants and parasites and symbionts. At the same time, the interaction of CLE peptides with other phytohormones, participating in these processes, is essentially(More)
The results of genetic analysis of the wavy shoots character supported the hypothesis on the existence of two genes, Wsh1 and Wsh2, whose mutations caused wavy shoots in radish lines 16 and 26, respectively. As shown by analysis of joint inheritance with marker characters, wavy shoots were inherited independently of the biochemical markers (genes Lap1, Ep,(More)
Genetic control of differentiation processes in radish was studied in vitro on the level of morphogenic capacities of explants. We have shown that when cultured on hormone-free MS medium (Murashige and Skoog, 1962), isolated radish cotyledons can produce callus and/or roots. At the same time, excised seedling apices placed on MS medium supplied with(More)
Tumor formation was studied in inbred radish lines that produce tumors on plant roots during flowering. In all radish lines under consideration, the sequences homologous to oncogenes tmr/tml of Agrobacterium tumefaciens were revealed by Southern hybridization. No sequences homologous to the tms locus of A. tumefaciens and the oncogenes of A. rhizogenes were(More)
Blueberries are an increasingly important h~ticultural crop in New Zealand and other coun~es. Fruit ripen over an extended period, with considerable differences in storage and other qualities. Tissue concentrations of abscisic acid (ABA), 1-aminocyciopmpane-l-carboxylic acid (ACC), malonyl-ACC and also ACC oxidase activity and ethylene evolution were(More)
