Autor: I. Machackova, V. I. Kefeli, R. V. Makarova, T. A. Borisova

Publikováno v: Plant Hormone Signal Perception and Transduction ISBN: 9789401065467

Transgenic plants carrying isopentenyl transferase (ipt) gene and normal tobacco plants (Nicotiana tabacum L.) were analyzed to compare their phytohormone status. Total cytokinin (zeatin, zeatin riboside, isopentenyladenine and isopentenyladenosine)

Various Conditions of Illumination and Ethylene Evolution

Autor: V. I. Kefeli, T. Y. A. Rakitina, F. Jalilova, A. E. Kalevich, P. V. Vlasov

Publikováno v: Cellular and Molecular Aspects of the Plant Hormone Ethylene ISBN: 9789048142491

The evolution of ethylene by seven-day green, etiolated, and red litght (650 nm) — irradiated pea seedlings (Pisum sativum L.) was studied. The production of ethylene was the greatest in green seedlings; illumination of etiolated seedlings by red l

Comparison ofin vivo activity of L-tryptophan synthas in plants with a low and a high content of L-tryptophan

Autor: Květa Vacková, I. Langer, J. Eder, V. I. Kefeli, M. Kutáček

Publikováno v: Biologia Plantarum. 20:181-186

The activity of L-tryptophan synthase (TS, E.C.4.2.1.20) was comparedin vivo in seedlings of plants high in L-tryptophan (L-trp) (pea and kohlrabi) and low in this amino acid (maize). In maize the TS was studied both in the normal and in the opaque-2

Regulation of growth and morphogenesis in phenotyplc and genotyplc dwarf peas

Autor: Ella M. Kof, Nina N. Protasova, V. I. Kefeli

Publikováno v: Biologia Plantarum. 29:22-27

White light suppressed the stem growth and promoted leaf expansion. With increased irradiance the light effect was enhanced. The morphogenetic effects induced by light and by dwarf-mutation are similar. However, the nature of phenotyplc and genotyplc

Gibberellins, Abscisic Acid, and Related Inhibitors in Branches and Bleeding Sap of Birch (Betula pubescens Ehrh.)

Autor: P. V. Vlasov, W. Dathe, V. I. Kefeli, G. Sembdner

Publikováno v: Biochemie und Physiologie der Pflanzen. 173:238-248

Summary The main acidic inhibitor in wood, bark and bleeding sap has been identified by GC-MS and ORD to be ABA1). The ABA level was high during dormancy (wood 1.5, bark 2.2 mg/kg fr. w.) and low after breaking of buds (wood 0.02, bark 0.08 mg/kg fr.

Analysis of specificities in the movement of cytoplasmic clusters in the cell ofAcetabularia mediterranea

Autor: Ella M. Kof, J. Hřib, V. I. Kefeli

Publikováno v: Biologia Plantarum. 24:410-414

The movement of cytoplasmic clusters of high density was studied in the stalk ofAcetabularia mediterranea using time-lapse microcinematography during regeneration. The kinetics of expansion and contraction of cytoplasmic clusters is described in acro
