Algalogically pure cultures were isolated from different aquatic ecosystems and identified as representatives of green algae, euglena algae, and cyanobacteria. Isolated cultures and collection strains of microalgae were screened for productivity. Induced mutagenesis (exposure to UV radiation, 254 nm, 40 Erg/mm ² ) and selection yielded a mutant strain C-2m2 of Chlorella pyrenoidosa...

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 136-140

Hairy root cultures of Rauvolfia verticillata were established and used to analyze the expression of the eight ajmalicine-pathway genes (the five MEP pathway genes, including DXR, MCT, MECS, HDS, and HDR}; the three ajmalicine-pathway-specific genes, including TDC, STR, and SGD) and ajmalicine accumulation in the cultures treated with ABA. In the ABA treatment, the five MEP-pathway genes were simultaneously...

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 97-104

The 7- to 8-day-old barley (Hordeum vulgare L.) seedlings grown in KNO3 solutions (1-40 mM) were characterized by the substrate activation of nitrate reductase (NR) in the apical leaf segments (1–2 cm in length), as well as by stimulated growth, broadened leaf blades, and by vigorously developed system of shortened roots. When the seedlings were grown in the presence of 20 mM KNO₃, the ability of...

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 131-135

Detached leaf is in the state of increasing water deficit; it is a good experimental model for looking into the hardening effect of adaptation of eight-day-old maize (Zea mays L.) seedlings to short-term drought (five days without watering). The light stage of photosynthesis and photosynthetic CO₂/H₂O exchange in detached leaves were studied. Specific surface density of leaf tissue (SSDL), the content...

Biosynthesis of fatty oils in higher plants

R. A. Sidorov, V. D. Tsydendambaev

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 1-18

Triacylglycerols (TAGs) are one of the most important storage compounds of higher plants; they are the basis for essentially all plant oils and are used by the cell as a reserve source of energy and carbon. Therefore, as a rule, plants store oils almost exclusively in their seeds. Plant oils are not only a major food and feed products, but also the raw material for obtaining many nonfood products...

Mechanisms of bioadhesion of macrophytic algae

E. R. Tarakhovskaya

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 19-25

During the evolution the benthic macrophytic algae developed effective mechanisms of bioadhesion enabling their attachment to almost any surface in the aqueous medium. The attachment of algal spores and zygotes includes two successive stages: the primary and the secondary (final) adhesion. Analysis of information on the composition of adhesive materials and attachment mechanisms in brown, green, and...

Effect of low dose of spermidine on physiological changes in salt-stressed cucumber plants

R. Radhakrishnan, I. J. Lee

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 90-96

The present study was aimed to assess the ameliorative potentiality of exogenously applied low dose of spermidine (Spd) (4.0 mL of 0.1 mM) against salt stress in cucumber (Cucumis sativus L.) plants. Salt stress inhibited plant growth, while Spd increased the shoot length and dry weight of leaves in salt-stressed plants. Chlorophyll, carotenoids, and sucrose contents were lower, and the accumulation...

The interrelationship between HCO ₃ ⁻ , NO ₃ ⁻ , and Cl⁻ as effective anions in the photosynthetic electron transport

M. E. H. Osman

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 33-37

Thylakoids were isolated from the leaves of three different plants (Pisum sativium L., Lactuca sativa L., and Raphanus sativus L.). The addition of HCO ₃ ⁻ to a suspension of salt-and HCO ₃ ⁻ -epleted thylakoids (suspended in salt-free medium) raised the rate of O₂ evolution up to fourfold. This stimulation could be partially replaced by the addition of chloride or nitrate ions. However, the addition...

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 38-46

The effects of salicylic acid (SA) on the rate of respiration and the activity of cyanide-resistant sensitive to salicylhydroxamic acid oxidation pathway in detached etiolated cotyledons of yellow lupine (Lupinus luteus L.) and mitochondria isolated from these cotyledons were studied. Cotyledon treatment with 1 mM SA for 12 h increased the rate of oxygen uptake predominantly due to the activation...

Mitochondrial retrograde regulation of HSP101 expression in Arabidopsis thaliana under heat stress and amiodarone action

D. V. Pyatrikas, E. G. Rikhvanov, I. V. Fedoseeva, N. N. Varakina, more

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 80-89

Heat stress in plants elevates the potential across the inner mitochondrial membrane (mtΔψ) and activates the expression of heat shock proteins (HSPs). The treatment of Saccharomyces cerevisiae cells with amiodarone (AMD) elevated the cytosolic Ca²⁺ level ([Ca²⁺]_cyt) in parallel with (mtΔψ) increase and led to the induction of Hsp104 synthesis. The hyperpolarization was presumably due to the increase...

Light-harvesting II complexes (LHCII) and photosystem II core complexes (PSIICC) were isolated from spinach (Spinacia oleracea L.) and reconstituted into phosphatidylcholine liposomes and, under heat stress, PSIICC-LHCII proteoliposomes were found to exhibit significantly higher oxygen evolution activity than PSIICC proteoliposomes lacking LHCII. In the presence of LHCII, the temperature of a 10-min...

Tyrosinase and superoxide dismutase activities of peroxidase in the vacuoles of beet roots

E. V. Pradedova, O. D. Nimaeva, I. S. Trukhan, R. K. Salyaev

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 70-79

In the absence of H₂O₂, isoforms of vacuolar phenol-dependent peroxidase (PO) in beet (Beta vulgaris) roots oxidized phenolic compounds like tyrosinases. Tyrosinase activity of PO manifested a clearly expressed pH-dependence with the optimum at pH of 8.0–9.0; peroxidase activity was the highest at pH 5.0–7.0. The inhibitory analysis confirmed a specificity of observed reactions. Along with tyrosinase...

S. P. Makarenko, T. A. Konenkina, G. G. Suvorova, M. V. Oskorbina

Russian Journal of Plant Physiology > 2014 > 61 > 1 > 119-123

The fatty acid (FA) composition of common pine (Pinus sylvestris L.) needle lipids was studied. It was shown that FA composition of needle lipids changed during the entire growth period (from March to October) under the influence of environmental factors (temperature, solar radiation) affecting the biosynthesis of chloroplast membrane lipids in pine needles. Among needle lipid FAs, unsaturated polymethylene-interrupted...

Role of mitochondria in the operation of calcium signaling system in heat-stressed plants

E. G. Rikhvanov, I. V. Fedoseeva, D. V. Pyatrikas, G. B. Borovskii, more

Russian Journal of Plant Physiology > 2014 > 61 > 2 > 141-153

Mild heat stress induces the expression of heat shock proteins (HSPs) that protect plants from death during damaging heat treatments. It was assumed that the appearance in the cell of denatured proteins triggers the expression of HSP; however, recent results show that protein denaturation is not a prerequisite for this process. In this work we discuss a hypothetical mechanism for activation under...

It was shown for the first time the presence of the soluble cytokinin-binding protein with a mol wt of 67 kD (CBP67) in the cyanobacterium Synechocysti sp. PCC 6803. CBP67 was isolated by two independent methods: by affinity chromatography on zeatin-Sepharose and by immunoaffinity chromatography on zeatin-Sepharose using monoclonal antibodies (mAb) raised against maize CBP70 (70 kD). The cytokinin-binding...
