Untangling metabolic and spatial interactions of stress tolerance in plants. 1. Patterns of carbon metabolism within leaves / K. Y. Biel [et al.] // Protoplasma. - 2010. - Vol. 245, Is. 1. - P49-73, DOI 10.1007/s00709-010-0135-7 . - ISSN 0033-183X

Аннотация: The localization of the key photoreductive and oxidative processes and some stress-protective reactions within leaves of mesophytic C3 plants were investigated. The role of light in determining the profile of Rubisco, glutamate oxaloacetate transaminase, catalase, fumarase, and cytochrome-c-oxidase across spinach leaves was examined by exposing leaves to illumination on either the adaxial or abaxial leaf surfaces. Oxygen evolution in fresh paradermal leaf sections and CO2 gas exchange in whole leaves under adaxial or abaxial illumination was also examined. The results showed that the palisade mesophyll is responsible for the midday depression of photosynthesis in spinach leaves. The photosynthetic apparatus was more sensitive to the light environment than the respiratory apparatus. Additionally, examination of the paradermal leaf sections by optical microscopy allowed us to describe two new types of parenchyma in spinach-pirum mesophyll and pillow spongy mesophyll. A hypothesis that oxaloacetate may protect the upper leaf tissue from the destructive influence of active oxygen is presented. The application of mathematical modeling shows that the pattern of enzymatic distribution across leaves abides by the principle of maximal ecological utility. Light regulation of carbon metabolism across leaves is discussed. В© 2010 Springer-Verlag.

Tolerance of wheat and lettuce plants grown on human mineralized waste to high temperature stress / S. A. Ushakova [et al.] // Advances in Space Research. - 2013. - Vol. 51, Is. 11. - P2075-2083, DOI 10.1016/j.asr.2013.01.017 . - ISSN 0273-1177

Аннотация: The main objective of a life support system for space missions is to supply a crew with food, water and oxygen, and to eliminate their wastes. The ultimate goal is to achieve the highest degree of closure of the system using controlled processes offering a high level of reliability and flexibility. Enhancement of closure of a biological life support system (BLSS) that includes plants relies on increased regeneration of plant waste, and utilization of solid and liquid human wastes. Clearly, the robustness of a BLSS subjected to stress will be substantially determined by the robustness of the plant components of the phototrophic unit. The aim of the present work was to estimate the heat resistance of two plants (wheat and lettuce) grown on human wastes. Human exometabolites mineralized by hydrogen peroxide in an electromagnetic field were used to make a nutrient solution for the plants. We looked for a possible increase in the heat tolerance of the wheat plants using changes in photosynthetically active radiation (PAR) intensity during heat stress. At age 15 days, plants were subjected to a rise in air temperature (from 23 В± 1 В°C to 44 В± 1 В°) under different PAR intensities for 4 h. The status of the photosynthetic apparatus of the plants was assessed by external 2 gas exchange and fluorescence measurements. The increased irradiance of the plants during the high temperature period demonstrated its protective action for both the photosynthetic apparatus of the leaves and subsequent plant growth and development. The productivity of the plants subjected to temperature changes at 250 W m-2 of PAR did not differ from that of controls, whereas the productivity of the plants subjected to the same heat stress but in darkness was halved.

The levels of organization of the photosynthetic apparatus and the control of production processes in phytocenoses under artificial-light culture / A. A. Tikhomirov, G. M.

Аннотация: The processes limiting the production in higher plant phytocenoses under an artificial-light culture are analyzed in relation to the multilevel organization of the photosynthetic apparatus (PA). The authors consider the feasibility of overcoming these limitations by optimizing the physical parameters of irradiation (the structure of the light spectrum, the rate, and the ratio of radiation fluxes in photosynthetically active radiation (PAR) and infrared (IR) regions) at the molecular, leaf, plant, and cenotic levels of PA organization. To illustrate this approach, the authors used a complex experiment in an artificial ecosystem to evaluate the efficiency of the light control of production processes in multispecies phytocenoses by alleviating or removing the factors that limit plant production at the various levels of PA organization. An artificial-light culture is seen as an instrument for solving several problems of theoretical and applied plant physiology and related disciplines in the future.

Аннотация: Presently, the most promising way of studying, forecasting, and enhancing of organisms' tolerance to harsh environmental impacts is considered to be the estimation of initial functional state of an organism's regulatory systems. To resolve the problem of photosynthetic apparatus (PSA) tolerance to harsh impacts at the level of such a complicated functional system as a plant leaf, it is necessary to assess integral responses of the leaf's PSA to the impact. At that, simple and versatile traits may have certain advantages. At present, chlorophyll fluorescence seems to be one of the main indices of PSA activity, which can be measured relatively fast and easy. One of the possible approaches to operational integrative assessment of PSA activity may consist in usage of the parameters introduced for the curves of chlorophyll fluorescence induction (CFI) slow phase. Temporal patterns of CFI are of special interest. The simplest index T-0.5 (i.e., half-time of chlorophyll fluorescence intensity decrease during the slow phase of CFI) appears to be an integral characteristic of activation rate with regard to a number of photo-assimilation and photo-protective processes in leaves. On basis of the studies, conducted earlier, and published data, we have analyzed the behavior of T-0.5 parameter with comparison to other CFI traits (namely: qN - non-photochemical quenching coefficient, ETR - electron transport rate, Phi(PSII) - effective quantum yield of PSII photochemistry, F-p/F-T ratio) under different conditions. The influence of leaf senescence, changes in intensity of excitation light, slight dehydration of plants and their recovery from water deficiency have been examined. The pattern of T-0.5 behavior, observed in laboratory experiments, and the results of its comparison with other indices of CFI give occasion to propose the usage of T-0.5 for indirect estimation of PSA activity when operational integrative monitoring of PSA state is required. Further studies are necessary for establishing quantitative relationships between PSA activity and fluorescence parameter T-0.5 under specific stress conditions.

Аннотация: The reaction of algae and cyano-bacteria photosynthetic apparatus on atmospheric sediments, incident solar radiation and wind velocity was estimated by measuring chlorophyll fluorescence using three-beam fluorescent diagnostics. As shown, wind in the spring positively affects the chlorophyll concentration but causes negative effect on phytoplankton photosynthetic activity in other seasons. Under conditions of high-intensity solar irradiation confervoid and colonial cyanobacteria, possessing gas vacuoles, have an advantage over plankton eukaryotic algae. Other response differences weren't observed.

Photosynthetic apparatus of cucumber and pea plants grown under red light with discrete or continuous spectra / E. N. Zavorueva [et al.] // Russian Journal of Plant Physiology. - 1996. - Vol. 43, Is. 2. - P191-199 . - ISSN 1021-4437

And thermoinduced changes in fluorescence yield -- Cucumis sativum -- Photo -- Photophosphorylation -- Pigments -- Pisum sativum
Аннотация: The effect of light sources with discrete or continuous spectra of red light (50 W/m2, 600-700 nm) on the structural and functional characteristics of chloroplasts were studied in leaves of cucumber (Cucumis sativum L.) plants, which die under strong red light, and pea (Pisum sativum L.) plants, which tolerate red light under the same conditions. Leaf condition was assessed by measuring thermo-and photoinduced changes in the chlorophyll fluorescence yield and the photochemical and photophosphorylating activities of the chloroplasts. Different responses of the pigment apparatus of pea and cucumber plants to red light with continuous or line spectra were revealed. Pea plants responded to discrete-spectrum light by changing P700 content, the ratio of antenna chlorophyll to P700, and the position of the low-temperature peak of the temperature-induced chlorophyll fluorescence yield. In cucumber plants, disturbances in the energy transfer from the short-wavelength pigments to chlorophyll a were observed. In both plants, the effects of line spectrum light on the pigment apparatus were reversible; the ratio of cyclic to noncyclic photophosphorylation, photosynthetic control, and the extent of the coupling of photosynthetic electron transport to photophosphorylation did not change compared to the control light. The need for examining the line spectra of light sources for growing plants under moderate intensities of artificial light (about 50 W/m2 of photosynthetically active radiation) is discussed.

Leaf age -- Photosystems 1 and 2 -- Radiation colour -- Specific leaf growth rate
Аннотация: The review deals with objective reasons that limit the use of chlorophyll fluorescence induction kinetics (Chl FIK) method in plant ecology. Based on the ontogenetic approach (analysis and comparison of the dynamics of the Chl fluorescence ratio Fp/Fs and physiological characteristics of plant leaves in ontogeny) possible criteria for the estimation of general plant resistance of photosynthetic apparatus (PSA) to prolonged stress affects are proposed. One of these criteria is the presence or absence of a steady-state phase in the dynamics of Chl fluorescence ratio Fp/Fs (or Rfd) of plant leaves after they stop growing. We also propose to use the duration of the steady-state phase and variability of Chl fluorescence ratios Rfd and Fp/Fs in this period for quantitative assessment of plant PSA resistance to prolonged stress during plant leaf ontogeny.

Ontogenetic approach in fluorescence studies of the photosynthetic apparatus of plants under stress / T. V. Nesterenko, A. A. Tikhomirov // Biophysics. - 2005. - Vol. 50, Is. 2. - P314-319 . - ISSN 0006-3509
Кл.слова (ненормированные):
Chlorophyll fluorescence -- Leaf -- Ontogeny -- Stress -- Cucumis sativus
Аннотация: The causes that limit the applicability of the chlorophyll fluorescence induction method to evaluating the state of the photosynthetic apparatus of leaves under long-term stress were analyzed. It was substantiated that it is necessary to use an ontogenetic approach, which consists in more accurately taking into account the age state of the plant leaves studied. Comparison of the calendar and ontogenetic methods for determining the leaf age by the example of cucumber plant under controlled conditions revealed significant differences in the results of evaluating the photosynthetic apparatus of plant leaves by the chlorophyll fluorescence induction method in two variants with contrasting illumination conditions (in white light at 400-700 nm and in stressful red light at 600-700 nm). It was shown that, under long-term stress, the unequivocal interpretation of the chlorophyll fluorescence induction parameters in evaluating the photosynthetic apparatus of plants depends significantly on the choice of the ontogeny period of the leaves of plants being compared and on the accuracy of determining their age.

Аннотация: An approach to searching for extraterrestrial life on the base of "autotroph" concept of the origin of life is presented in the paper, According to this concept the origin of life took place in three stages. The first stage was developed inside the global geochemical cycle in which the turnover of different chemical transformations was implemented by solar radiation and/or heat energy of bowels of the Earth. At the second stage, after the autocatalytic systems have emerged these systems evolved as a result of "natural selection" by autocatalysis parameters up to emergence of special inheritance systems that drastically improved the autocatalysis parameters. The best in terms of autocatalysis parameters were the autocatalysis systems based on phase-separated particles where complex structures can form not only on the basis of covalent interactions. Such autocatalysis systems can emerge only in liquid in a certain range of temperatures and pressures. At this stage the geochemical cycle complicated involving new substances. At the third stage the evolution involved improvement of inheritance systems resulting in formation of the modern type of genetic apparatus. This concept formed the basis to consider approaches to experimental modeling of major aspects of the origin of life and to outlining some general features of life that can extend the sensitive horizon of searching for extraterrestrial life.

Аннотация: Productivity values, sodium accumulation in aboveground biomass, and photosynthetic indices of watercress (Nasturtium officinale) leaves were investigated under conditions resembling artificial closed ecological systems (CES). The seedlings were grown on nutrient media with various NaCl concentrations (0.7, 1.4, and 1.8 g/L) for 7, 14, and 19 days after transferring them to saline solutions. The productivity of plants on the seventh day of their growth on saline media did not differ from that of control plants. The decrease in plant productivity was noted in all the treatments starting from the 14th day after transferring the plants to saline solutions. When NaCl concentration in the nutrient solution was raised from 0.7 to 1.8 g/L, a significant increase in relative Na+ content in plant tissues was observed, regardless of the duration of NaCl treatment. A substantial decrease in chlorophyll (a + b) to carotenoid content ratio was noted on the seventh and 14th days in plants grown at 1.8 g/L NaCl. In plants treated for 7 days with 0.7 and 1.4 g/L NaCl, the content of chlorophylls a and b and carotenoids was found to increase, which indicates the tolerance of N. officinale to CES conditions. The relative content of chlorophylls a and b in the light-harvesting chlorophyll (a + b) complex was independent of the extent of salinity. The maximum quantum yield of photosystem II reaction in N. officinale plants had typically high values (Y(II)(max) of 0.755 +/- 0.007). Using the Imaging Maxi version of the pulse amplitude-modulated (PAM) fluorometer, it was found that light curves for the effective quantum yield of photochemical and nonphotochemical fluorescence quenching (Y(II) and Y(NPQ), respectively) differed appreciably between the salt-treated and untreated plants in the case of long-term cultivation (19 days) at 0.7 and 1.4 g/L NaCl. The treatment with 1.8 g/L NaCl for the period from 14 to 19 days had no effect on light curves of Y(II) and Y(NPQ). It is argued that N. officinale can be used as a source of NaCl for humans under CES conditions.

Аннотация: The purpose of this work was to study the full-scale potential use of human mineralized waste (feces and urine) as a source of mineral elements for plant cultivation in a biological life support system (BLSS). Plants that are potential candidates for a photosynthesizing link were grown on a neutral solution containing human mineralized waste. Spring wheat Triticum aestivum L., peas Pisum sativum L. Ambrosia cultivar and leaf lettuce Lactuca sativa L., Vitaminny variety, were used. The plants were grown hydroponically on expanded clay aggregates in a vegetation chamber in constant environmental conditions. During plant growth, a determined amount of human mineralized waste was added daily to the nutrient solution. The nutrient solution remained unchanged throughout the vegetation period. Estimated plant requirements for macro-elements were based on a total biological productivity of 0.04 kg day-1 m-2. As the plant requirements for potassium exceeded the potassium content of human waste, a water extract of wheat straw containing the required amount of potassium was added to the nutrient solution. The Knop's solution was used in the control experiments. The experimental and control plants showed no significant differences in state or productivity of their photosynthetic apparatus. A small decrease in total productivity of the experimental plants was observed, which might result in some reduction of O{cyrillic}2 production in a BLSS. В© 2009 COSPAR.

Аннотация: The range of variations in parameter tau(0.5) - half-time of fluorescence intensity decrease during the slow phase of chlorophyll fluorescence induction (CFI) - has been studied during ontogeny of leaves of monocotyledonous and dicotyledonous plants in plant communities of different structures. Plants were grown hydroponically on expanded clay aggregate in growth chambers, under PPFD of 400 mu mol(photon) m(-2) s(-1), under controlled conditions. Analysis of the literature data and results of experimental observations of tau(0.5) behavior compared to other CFI parameters, nonphotochemical quenching coefficient, q(N), in particular, leads to the conclusion that parameter tau(0.5) can be effectively used for indirect estimation of variations in the activity of photosynthetic apparatus during ontogeny of plant leaves.

Аннотация: The use of mineralized human wastes as a basis for nutrient solutions will increase the degree of material closure of bio-technical human life support systems. As stress tolerance of plants is determined, among other factors, by the conditions under which they have been grown before exposure to a stressor, the purpose of the study is to investigate the level of tolerance of chufa (Cyperus esculentus L.) plant communities grown in solutions based on mineralized human wastes to a damaging air temperature, 45 °C. Experiments were performed with 30-day-old chufa plant communities grown hydroponically, on expanded clay aggregate, under artificial light, at 690 ?mol m-2 s-1 PAR and at a temperature of 25 °C. Plants were grown in Knop's solution and solutions based on human wastes mineralized according to Yu.A. Kudenko's method, which contained nitrogen either as ammonium and urea or as nitrates. The heat shock treatment lasted 20 h at 690 and 1150 ?mol m -2 s-1 PAR. Chufa heat tolerance was evaluated based on parameters of CO2 gas exchange, the state of its photosynthetic apparatus (PSA), and intensity of peroxidation of leaf lipids. Chufa plants grown in the solutions based on mineralized human wastes that contained ammonium and urea had lower heat tolerance than plants grown in standard mineral solutions. Heat tolerance of the plants grown in the solutions based on mineralized human wastes that mainly contained nitrate nitrogen was insignificantly different from the heat tolerance of the plants grown in standard mineral solutions. A PAR intensity increase from 690 ?mol m -2 s-1 to 1150 ?mol m-2 s-1 enhanced heat tolerance of chufa plant communities, irrespective of the conditions of mineral nutrition under which they had been grown. © 2014 COSPAR.
