The role of phytohormones ethylene and auxin in plant-nematode interactions
Pleiades Publishing Ltd - Tập 56 - Trang 1-5 - 2009
The phytohormones ethylene and auxin regulate many important processes in plants, including cell differentiation, cell expansion, and responses to abiotic stresses. These hormones also play important roles in many plant-pathogen interactions, including regulation of plant defense responses and symptom development. Sedentary plant-parasitic nematodes, which require the formation of a complex feedin...... hiện toàn bộ
Transformation of CW-15 Mutant Cells of Chlamydomonas reinhardtii Dang. with pCTVHyg Plasmid
Pleiades Publishing Ltd - Tập 49 - Trang 832-838 - 2002
A pCTVHyg plasmid was constructed in a unicellular green alga Chlamydomonas reinhardtii Dang. by using the hygromycin phosphotransferase gene (hpt) as a selectable marker and the Escherichia coli transposon Tn5 under the early SV40 viral gene promoter. CW-15 mutant cells devoid of cell walls were transformed by electroporation in an electric field of 1 kV/cm and a pulse duration of 2 ms. A suspens...... hiện toàn bộ
Nonmonotonic Redox Conversions of P700 in Leaves Irradiated with Far-Red Light Originate from Variable Contributions of Several Alternative Electron Transport Pathways during the Induction Period
Pleiades Publishing Ltd - Tập 52 - Trang 571-577 - 2005
The origin of nonmonotonic changes in the redox state of P700, the primary electron donor of PSI, was investigated on predarkened barley (Hordeum vulgare L.) leaves exposed to far-red light. To accomplish this, the relaxation kinetics of absorbance changes at 830 nm, reflecting the dark reduction of P700+, were measured at different stages of the induction curve. The onset of far-red light resulte...... hiện toàn bộ
Dependence of chlorophyll P700 redox transients during the induction period on the transmembrane distribution of protons in chloroplasts of pea leaves

Apoptosis-like degradation of pollen grains in siberian squill related to the lack of low temperatures during their development
Pleiades Publishing Ltd - Tập 56 - Trang 852-857 - 2009
Low temperature is necessary for completing the cycle of anther development in early-spring ephemeroids. Pollen grains were investigated in Scilla sibirica L. growing under natural conditions in a park and taken to a greenhouse for the cold season. In control plants grown in the open ground, the development of microspores was normal. The plants transferred to the greenhouse sharply differed from c...... hiện toàn bộ
Isolation and Comparison of Eight SWEET17 Genes from Six Loquat Cultivars
Pleiades Publishing Ltd - Tập 67 - Trang 1063-1075 - 2020
The plant SWEET (Sugars Will Eventually be Exported Transporters) proteins, as newly discovered sugar transporters, play various important roles during plant depending on the transmembrane gradient of sugar concentration. SWEET17 protein is one of the SWEET family members transporting fructose in particular. In this study, we identified eight SWEET17s from six loquats (Eriobotrya japonica (Thunb.)...... hiện toàn bộ
Developmental pattern in the formation of various multienzyme complexes associated with Benson-Calvin cycle in cotton leaves
Pleiades Publishing Ltd - Tập 57 - Trang 175-180 - 2010
An electrophoretically homogeneous preparation of a multienzyme complex with a mol wt of 520 ± 20 kD was isolated from 15- to 25-day-old cotton (Gossypium hirsutum L.) leaves uniform in their age and position on the shoot (3rd to 4th leaves from the top when the plants possessed 5–6 true leaves). When cotton leaves were sampled at the stage of budding and flowering, two complexes with mol wts of 5...... hiện toàn bộ
Effect of weak constant magnetic field on the composition and content of lipids in radish seedlings at various temperatures
Pleiades Publishing Ltd - Tập 57 - Trang 52-61 - 2010
We studied the effects of weak permanent homogenous hirizontal magnetic field (PMF) (400 A/m) on the composition and content of lipids and composition of their fatty acids (FAs) in radish (Raphanus sativus L. var. radicula D.C., cv. Rosovo-krashyi s belym konchikom) seedlings at temperatures of 20 and 10°C. We compared lipid composition and content in seedlings at the phase of developed cotyledons...... hiện toàn bộ
Osmotic Water Permeability of Vacuolar and Plasma Membranes Isolated from Maize Roots
Pleiades Publishing Ltd - Tập 48 - Trang 287-293 - 2001
The method of stopped flow was used to follow the changes in light scattering by the vesicles of plasmalemma and tonoplast isolated from maize (Zea maysL.) roots and treated by osmotic pressure. In both membrane preparations, the rate of the process depended on the osmotic gradient and was described with the simple exponential function. The rate constants derived from these functions were the foll...... hiện toàn bộ
Metabolite transport across the peribacteroid membrane during broad bean development
Pleiades Publishing Ltd - Tập 54 - Trang 184-190 - 2007
A temporal pattern of the peribacteroid membrane (PBM) transport function was studied. Spectrophotometric recording was used for establishing the effect of carbon-and nitrogen-containing substrates (malate, succinate, and glutamate) on the acidification of the peribacteroid space and the intensity of light scattering in the symbiosome suspension from broad bean (Vicia faba L.) root nodules of diff...... hiện toàn bộ
