Physiological changes in them in post-stress emerging Ctenanthe setosa plants under drought conditions
Pleiades 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
Elevated Temperature during Seedling Stage in Different Maize Varieties: Effect on Seedling Growth and Leaf Physiological Characteristics
Pleiades Publishing Ltd - Tập 69 - Trang 1-11 - 2022
Q. Wang, Z. Q. Xia, S. B. Zhang, Y. F. Fu, G. X. Zhang, H. D. Lu
Due to climate change, extreme high temperature weather is occurred frequently, which may cause a serious decline in crop yield. The growth status of maize seedlings directly affects the formation of later yield. However, there are insufficient understanding and studies on the maize seedling growth and physiological characteristics of leaves under high temperature stress at present. Hence, this ex...... hiện toàn bộ

Regulation of Phospholipase D Activity by Light and Phytohormones in Oat Seedlings
Pleiades 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
Molecular Cloning and the Expression Pattern of a Phospholipid Hydroperoxide Glutathione Peroxidase in Kalidium foliatum under NaCl Treatment
Pleiades Publishing Ltd - Tập 67 - Trang 750-757 - 2020
Z. G. Wang, P. X. Zhang, Y. T. Shao, T. T. Xu, X. Y. Jia, X. Q. Zhang, W. T. Si, J. Jia
The halophyte Kalidium foliatum (Pall.) Moq. exhibits strong tolerance to salinity. Salt stress leads to reactive oxygen species (ROS) production, and high contents of ROS are harmful to plants. The phospholipid hydroperoxide glutathione peroxidase (PHGPx) responds positively to damage induced by ROS. To understand the mechanism of tolerance to salt stress in halophytes, a PHGPx gene of K. foliatu...... hiện toàn bộ
Effect of Light Quality on Nitrogen Metabolism of Radish Plants
Pleiades 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 level
Pleiades Publishing Ltd - Tập 53 - Trang 548-555 - 2006
N. A. Moiseeva, V. N. Serebryakova, L. Nardi, S. Lucretti, R. G. Butenko
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 plants
Pleiades 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
