Two grain amaranth transcription factor (TF) genes were overexpressed in Arabidopsis plants. The first, coding for a group VII ethylene response factor TF (i.e., AhERF-VII) conferred tolerance to water-deficit stress (WS) in transgenic Arabidopsis without affecting vegetative or reproductive growth. A significantly lower water-loss rate in detached leaves coupled to a reduced stomatal opening i...

this study was conducted to determine the combined effects of salicylic acid (sa) and arbuscular mycorrhizal fungi (amf) (glomus mosseae) symbiosis on the growth of pistachio seedlings (pistacia vera ‘abareqi’) grown in the greenhouse under different drought stress (ds) levels. the arbuscular mycorrhizal fungi (amf) colonization or exogenous sa treatment could increase ‘abareqi’ pistachio seedl...

both poor germination and crop establishment due to water stress and salinity are among the most important limitations for production in semi-arid regions such as iran. to evaluate the response of four genotypes of triticale (et-82-15، et-82-8، et-79-17 and juanillo-92) to different water potentials caused by salinity and/or drought and recognizing the germination and seedling establishment, a ...

BACKGROUND AND AIMS The genus Eucalyptus occupies a broad ecological range, forming the dominant canopy in many Australian ecosystems. Many Eucalyptus species are renowned for tolerance to aridity, yet inter-specific variation in physiological traits, particularly water relations parameters, contributing to this tolerance is weakly characterized only in a limited taxonomic range. The study test...

Chickpea is mostly grown on stored soil moisture, and deep/profuse rooting has been hypothesized for almost three decades to be critical for improving chickpea tolerance to terminal drought. However, temporal patterns of water use that leave water available for reproduction and grain filling could be equally critical. Therefore, variation in water use pattern and root depth/density were measure...

BACKGROUND Crossed high alcohol preferring (cHAP) mice were selectively bred from a cross of the HAP1 × HAP2 replicate lines, and we demonstrate blood ethanol concentrations (BECs) during free-choice drinking that are reminiscent of those observed in alcohol-dependent humans. Therefore, this line may provide an unprecedented opportunity to learn about the consequences of excessive voluntary eth...

Pioneer tree species have acquisitive leaf characteristics associated with high demand of light and water, and are expected to be shade and drought intolerant. Using leaf functional traits (specific leaf area, photosynthetic rate, relative water content and stomatal conductance) and tree performance (mortality rate) in the field, we assessed how shade and drought tolerance of leaves are related...

Injection of endotoxin of Gram-negative bacilli into NCS mice caused an immediate reduction or interruption of water intake by these animals, with a resultant loss of body weight. Endotoxins prepared by three different techniques from four different cultures of Gram-negative bacilli yielded products having approximately the same activity in inhibiting water intake. The minimum effective dose wa...

Abiotic stress is one of the major limiting factors for plant development and productivity, which makes it important to identify microorganisms capable of increasing plant tolerance to stress. Dark septate endophytes can be symbionts of plants. In the present study, we evaluated the ability of dark septate endophytes isolates to reduce the effects of water stress in the rice varieties Nipponbar...
