Abstract:

Freeman maples (Acer × freemanii E. Murray) are marketed as stress-resistant alternatives to red maples (Acer rubrum L.), but few data from direct comparisons of these species are available. As a first step in comparing the stress resistance of red maple and Freeman maple, responses to drought were studied in Acer × freemanii `Autumn Fantasy', `Celebration', and `Marmo'. Plants grown from rooted cuttings were treated by withholding irrigation through four drought cycles of increasing severity that were separated by irrigation to container capacity. Drought reduced shoot dry mass, root dry mass

Abstract:

The drought tolerances of the warm temperate rainforest species Tristaniopsis laurina and Acmena smithii were examined. Using pressure bomb techniques the tissue water relations of hardened juvenile and adult material were measured. T. laurina showed relatively little physiological drought tolerance in either the juvenile or adult plants, whereas A. smithii showed an increase in physiological drought tolerance in adult plants. Direct observations of droughted hardened 9-month-old seedlings revealed a relatively high leaf conductance in T. laurina seedlings with wilting becoming generalised aft

Abstract:

A meta-analysis of 520 reports published during the last 20 years on transgenic and mutant plants generated towards drought resistance revealed a total of at least 487 tested transgenic plants involving at least 100 genes claimed to be functional towards drought resistance. During this period, the rate of reported new experimental transgenic model or crop plants for drought resistance has been increasing exponentially. Despite these numbers, qualified sources of information indicate a very limited impact on global dryland agriculture, whereas the genetically modified (GM) market hardly recogni

Abstract:

γ-aminobutyric acid (GABA) is a non-protein amino acid involved in various physiological processes; it aids in the protection of plants against abiotic stresses, such as drought, heavy metals, and salinity. GABA tends to have a protective effect against drought stress in plants by increasing osmolytes and leaf turgor and reducing oxidative damage via antioxidant regulation. Guard cell GABA production is essential, as it may provide the benefits of reducing stomatal opening and transpiration and controlling the release of tonoplast-localized anion transporter, thus resulting in increased water-

Abstract:

Previous investigations have shown that the SUPPRESSORS OF MAX2 1-LIKE6, 7 and 8 (SMXL6, 7 and 8) proteins redundantly repress strigolactone (SL) signaling in plant growth and development. Recently, a growing body of evidence indicated that SLs positively regulate plant drought resistance through functional analyses of genes involved in SL biosynthesis and positive regulation of SL signaling. However, the functions of the SL-signaling negative regulators SMXL6, 7 and 8 in drought resistance and the associated mechanisms remain elusive. To reveal the functions of these SMXL proteins, we analyze

Abstract:

The effect of chilling on growth and plant hydraulic properties in a drought-resistant clone (CN5) and a drought-sensitive clone (ST51) of Eucalyptus globulus Labill. was evaluated. Chilling (10/5°C, day/night) led to a general decrease in growth of both clones and significant reductions in root hydraulic conductivity, rate of photosynthesis and stomatal conductance in comparison to plants grown at control temperature (24/16°C). The drought-resistant CN5 clone maintained higher root growth and lower leaf-to-root-area ratio than the drought-sensitive ST51 clone, in both temperature treatments.

Colonization of roots by arbuscular mycorrhizal (AM) fungi can increase host resistance to drought stress, although the effect is unpredictable. Since AM symbiosis also frequently increases host resistance to salt stress, and since drought and salt stress are often linked in drying soils, we speculated that the AM influence on plant drought response may be linked to AM influence on salt stress. We tested the hypothesis that AM-induced effects on drought responses would be more pronounced when plants of comparable size are exposed to drought in salinized soils.

The climate of Ukraine is changing, that causes an uneven distribution of temperatures and precipitations during the growing season. As a result, there are periods of prolonged droughts with temperatures above +35 °С. In such periods, are observed the appearance of the sun-burn spots on the leaves and berries mass loss and as well loss of 50 % of the

Abstract:

There was an increase and intensification of droughts in connection with global climate change in recent decades. Not all plant organisms are able to adapt to changing environmental conditions. Therefore, the question of stressresistant (drought-resistant) genotypes selection for breeding is quite urgent. This problem also concerns forest tree plants, including Scots pine, which is one of the main foresters in the Voronezh region. The results of vegetative and generative sphere analysis of individual Scotch pine trees with the help of biotechnology, molecular-genetic and cytogenetic method are

Abstract:

Water regime of plants, characteristic of a certain variety, largely determines the resistance of plants to drought. Drought affects, first of all, such indicators as water absorption capacity, water retention capacity, water deficit and changes in total water content in the process of ontogenesis. Studying and taking into account a number of parameters of water regime can significantly increase the reliability of the assessment of plants for drought resistance. The purpose of the current study was to investigate the water regime of the winter bread wheat varieties under an acute drought and t

The results of studying the behaviour of sulphoquinovosyldiacylglycerol (SQDG) during environmental-factor action are discussed. Low-temperature action caused SQDG accumulation in 1-year-old shoot bark of resistant apple varieties, and was especially striking in the Siberia apple, a variety of extreme hardiness. Another unfavourable factor, high temperature, induced SQDG accumulation in leaves and chloroplasts of drought-resistant plants while in sensitive plants a decrease in its content took place. Water deficit caused the same effect. SQDG increase was also observed in field experiments wit

Abstract:

Drought stress causes recurrent damage to a healthy ecosystem because it has major adverse effects on the growth and productivity of plants. However, plants have developed drought avoidance and resilience for survival through many strategies, such as increasing water absorption and conduction, reducing water loss and conversing growth stages. Understanding how plants respond and regulate drought stress would be important for creating and breeding better plants to help maintain a sound ecosystem. Epigenetic marks are a group of regulators affecting drought response and resilience in plants thro

The yield potential and quality of main cereals crop plants including maize, wheat, rice and barley have improved through breeding and introduction of transgenic crop plants from last three decades. There has been intensive research for the improvement of resistance against biotic and abiotic environmental conditions to safe the potential of cereal crop plants. Among abiotic stresses drought and heat are two most important abiotic factors which caused major loss in yield and quality of crop plants. The heat stress leads towards drought due to loss of water from soil and plant surfaces, therefo

Abiotic stresses (e.g., salinity, drought, cold, oxidative stress) can be major factors limiting plant productivity worldwide. We sought to increase abiotic stress resistance in cucumber by expressing the A. thaliana transcription factors CBF1and CBF3, which regulate genes responsible for enhanced dehydration-stress resistance in Arabidopsis. Our previous studies in the greenhouse and field demonstrated increased salinity tolerance in CBF-expressing cucumber lines. In the current studies, we tested response of CBF-cucumber plants to drought, chilling, and oxidative stresses. Transgenic cucumbe

Along with its horticultural uses, silver maple (Acer saccharinum L.) can be grown for biomass in areas that vary greatly in annual rainfall and temperature. Silver maples from five provenances ranging from 33 to 46° N latitude were subjected to drought stress and to high root-zone temperature (RZT) in separate experiments to assess their suitability as biomass sources. In the drought experiment, control plants were irrigated every 2 days, while stressed plants were irrigated every 15 days. Initial results indicated provenance differences among control plants in dry mass, leaf area, and transp

Abstract Arbuscular mycorrhizas (AMs) prevail in warm and dry climates and ectomycorrhizas (EMs) in cold and humid climates. We suggest that the fungal symbionts benefit their host plants especially in the corresponding conditions. The hypothesis tested was that AM plants are more drought-resistant than EM or nonmycorrhizal (NM) plants. Grey alder (Alnus incana (L.) Moench) seedlings were inoculated with two species of either AM or EM fungi or none. In one controlled-environment experiment, there was a watering and a drought treatment.

bZIP transcription factors have been reported to be involved in many different biological processes in plants. The ABA (abscisic acid)-dependent AREB/ABF-SnRK2 pathway has been shown to play a key role in the response to osmotic stress in model plants. In this study, a novel bZIP gene, FtbZIP5, was isolated from tartary buckwheat, and its role in the response to drought and salt stress was characterized by transgenic Arabidopsis. We found that FtbZIP5 has transcriptional activation activity, which is located in the nucleus and specifically binds to ABRE elements. It can be induced by exposure
