Physiological changes in them in post-stress emerging Ctenanthe setosa plants under drought conditionsPleiades Publishing Ltd - Tập 55 - Trang 48-53 - 2011
A. Saglam, A. Kadioglu, R. Terzi, N. Saruhan
The capability of Ctenanthe setosa (Rosc.) Eichler (Marantaceae), pre-exposed to severe drought stress, of adaptation to a new drought conditions was investigated. C. setosa unstressed plants were exposed to drought period of 70 days. These plants were named as primary-stress plants (PS). They were trimmed, and new plants were produced from their rhizomes. New growing plants were named as post-str...... hiện toàn bộ
Regulation of Phospholipase D Activity by Light and Phytohormones in Oat SeedlingsPleiades Publishing Ltd - Tập 51 - Trang 769-773 - 2004
E. M. Kabachevskaya, G. V. Lyakhnovich, I. D. Volotovskii
The effect of synthetic analogs of phytohormones and red light absorbed by phytochrome on the phospholipase D activity (PLD) was studied in oat (Avena sativa L.) seedlings. ABA manifested a short-term stimulating effect on PLD activity in the green seedlings and inhibited phospholipase activity in the etiolated plants. Kinetin inhibited enzyme activity in the etiolated seedlings and did not affect...... hiện toàn bộ
Effect of Light Quality on Nitrogen Metabolism of Radish PlantsPleiades Publishing Ltd - Tập 52 - Trang 304-310 - 2005
S. N. Maevskaya, N. G. Bukhov
The long-term action of blue or red light on nitrogen metabolism was studied in radish (Raphanus sativus L.) plants. The potential activity of nitrate reductase (NR) in vivo and its maximum activity in vitro, the content of soluble protein and free amino acids were determined in the course of the growth of a third leaf of radish plants. The effect of light quality on NR activity was found to depen...... hiện toàn bộ
Organization of initial stages of somatic embryogenesis in tissue culture of Citrus sinensis cv. Tarocco at the organismal levelPleiades Publishing Ltd - Tập 53 - Trang 548-555 - 2006

Four-step protocol was established for the in vitro regeneration of Citrus sinensis cv. Tarocco somatic embryos that were morphologically similar to small somatic embryos in vivo. The regeneration procedure comprises a mechanical destruction of embryogenic culture to obtain proembryogenic cell masses (PEMs) (step 1) followed by culturing on three different media (steps 2–4). The approach developed...... hiện toàn bộ
Exogenous GA3 and flowering induce the conversion of artemisinic acid to artemisinin in Artemisia annua plantsPleiades Publishing Ltd - Tập 52 - Trang 58-62 - 2005
Y. S. Zhang, H. C. Ye, B. Y. Liu, H. Wang, G. F. Li
The contents of artemisinin and artemisinic acid were monitored in the Artemisia annua plants treated with GA3 at vegetative and flowering initiation stages. The highest artemisinin content was observed at full bloom. The decrease in artemisinic acid content occurred during the transition from the vegetative stage to the beginning of flowering. Endogenous GA3 content in the leaves peaked at full b...... hiện toàn bộ
Histological Structure and Composition of Secondary Metabolites in Cell Culture of Drosera rotundifolia L.Pleiades Publishing Ltd - Tập 69 - Trang 1-11 - 2022
M. T. Khandy, G. K. Chernoded, V. P. Grigorchuk, Yu. V. Vereshchagina, A. V. Morshneva, T. Yu. Gorpenchenko
Long-term growing callus cultures of D. rotundifolia were obtained for the first time: morphogenic line Green and partially differentiated rolC-transgenic line Red. Histological analysis revealed the presence of organogenesis and direct somatic embryogenesis in the Green line and cell differentiation in the Red line. Based on the HPLC method with UV and mass selective detection, 11 compounds were ...... hiện toàn bộ
