Fruit flies of the genus Drosophila have independently invaded deserts around the world on numerous occasions. To understand the physiological mechanisms allowing these small organisms to survive and thrive in arid environments, we performed a phylogenetic analysis of water balance in Drosophila species from different habitats. Desert (cactophilic) species were more resistant to desiccation tha...
COIIMAN, M. D., BLEDSOE, C. S., and LOPUSHINSKY, W. 1989. Pure culture response of ectomycorrhizal fungi to imposed water stress. Can. J. Bot. 67: 29-39. The ability of ectomycorrhizal fungal isolates to tolerate imposed water stress in pure culture was examined in 55 isolates of 18 species. Water potential treatments, adjusted with polyethylene glycol, were applied to Petri dish units. These u...
Stress and chronic pain have been shown to prevent the development of tolerance to morphine analgesia, which appears to be related to neuroendocrine activity and alternation in neurochemicals. Also the involvement of nitric oxide (NO) has been implicated in tolerance to morphine analgesia. In our pervious study, we showed that co-administration of swim stress (ss) with chronic morphine, prevent...
We tested the hypothesis that reduced root cortical cell file number (CCFN) would improve drought tolerance in maize (Zea mays) by reducing the metabolic costs of soil exploration. Maize genotypes with contrasting CCFN were grown under well-watered and water-stressed conditions in greenhouse mesocosms and in the field in the United States and Malawi. CCFN ranged from six to 19 among maize genot...
This experiment was conducted at the Research Farm of Isfahan University of Technology, Najafabad, Iran in 2014 and 2015 to evaluate drought tolerance indices of some sesame (Sesamum indicum L.) genotypes. In this study, 21 sesame genotypes isolated from different local populations along with seven exotic cultivars were evaluated at two irrigation regimes, using a randomized complete block desi...
Drought stress is the major problem in arid and semi-arid regions of the world. Investigating the response of different cultivars of crop plants to drought stress can help to select the tolerant ones for agriculture in arid lands. In this study, a greenhouse experiment was conducted as a factorial experiment based on completely randomized design with two common bean cultivars (Phaseolus vulgari...
the selection of high yielding and stress tolerance plant genotypes with the highest water use efficiency and productivity is one of the most important tools for field water management in arid and semi-arid regions. this study was conducted to identify drought tolerant flax families with the highest irrigation water productivity (iwp) among a population of 119 f3 families derived from a cross b...
Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution. Marine ectotherms' thermal tolerance is limited by their ability to maintain aerobic metabolism (oxygen- and capacity-limited tolerance), and is functionally associated with...

abstract to assay the effect of acetylsalicylic acid pretreatment on enhancement of yield and yield components of barley (reihan-03) under water stress condition, an experiment was conducted as a spilt-plot arrangement based on randomized complete block design with four replications at the research field of shahid bahonar university of kerman, iran, in 2012-2013. irrigation condition was arrang...
