“…In the present study, in response to controlled severe drought, the expression of HvHsdr4 was enhanced only at the intermediate stage of drought treatment (9 days) in Yarmouk genotype. Consistent with this result, HvHsdr4 gene in different genotypes of barley that were exposed to progressive drought of three levels (30%, 20%, and 10% of FC) was differentially expressed among genotypes and among the different levels of drought stress (de Mezer et al 2014). The highest expression of this gene was shown when the soil moisture reached 10%, which is considered a very severe drought (de Mezer et al 2014).…”

“…Plant response to drought is significantly dependent on the growth stage of plants, and the severity and duration of drought stress (Talamè et al 2007;Akash et al 2009;Harb et al 2010;Claeys et al 2014;de Mezer et al 2014). In addition, plant species and varieties are significant factors in determining plants' response to drought (Guo et al 2009).…”

“…Because it is a diploid plant (2n = 14) and it grows in a wide range of habitats, barley is an excellent model for physiological and genetic studies (Forster et al 2000;Diab et al 2004). Previous studies on barley under dehydration and drought stress have shown differential changes at the physiological, biochemical, and molecular levels (Ozturk et al 2002;Diab et al 2004;Talamè et al 2007;Guo et al 2009;de Mezer et al 2014). Drought tolerance depends on the type of drought stress in terms of drought intensity and duration and the developmental stage of plants at the beginning of drought stress.…”

“…At the biochemical level, sensitive plants experience significant oxidative stress under drought stress (Hasheminasa et al 2012;Marok et al 2013). At the molecular level, both global gene expression profiling and the expression of a set of droughtresponsive genes revealed a differential response in drought-tolerant plants versus drought-sensitive plants (Guo et al 2009;de Mezer et al 2014).…”

Drought is a major abiotic stress that restricts growth and productivity of many crops. The objectives of this study were to assess the morphological and physiological responses of barley plants at the vegetative stage to controlled severe drought, and to test the expression of drought-responsive genes (HvHsdr4, HvNCED2, HvDHN1, HvDHN9, and HvCBF3) in a time course of drought treatment. Barley plants of two genotypes (Rum and Yarmouk) were exposed to controlled severe drought (25% field capacity) in a greenhouse experiment. The two genotypes showed a similar and significant reduction in net photosynthetic rate and plant height. At the molecular level, a differential gene expression of drought-responsive genes was shown between the two genotypes. The results indicate that drought-responsive genes can be useful marker genes to study the differential response of barley genotypes to drought stress conditions.

“…In Georgie P N decreased at mild drought and stayed at almost the same level in severe drought. The decrease of P N in mild drought conditions was reported before in barley (de Mezer et al 2014). The basis of the reduction in net carbon (P N ) efficiency during increasing water deficit has not been fully explained yet.…”

Spring drought can adversely affect the productivity of barley (Hordeum vulgare L.) by reducing the yield. Because seed osmopriming can enhance crop productivity, we examined the potential of CaCl 2 treatment to improve drought tolerance in spring barley. Initially, we applied the priming procedure (5, 50, and 500 mM) to caryopses and assessed its effectiveness using a routine germination test, followed by measuring the level of divalent cations. Since drought adaptation is a complex phenomenon, we tested a comprehensive set of physiological parameters including (1) relative water content (RWC), (2) gas exchange parameters, and (3) photosynthetic pigments concentration in leaves of 3-week-old plants developed from the seeds subjected to osmopriming, followed by exposure to increasing water shortage. The plants were sampled at two selected time points, determined by soil moisture retention (pF = 3.6 and 4.2). The effect of CaCl 2 pretreatment was characterized in three distinct spring barley varieties, which differed in their response to drought stress (drought-tolerant Sebastian and Cam/B1/C1 and drought-susceptible Georgie), to assess potential interactions between osmopriming and genetically determined drought tolerance. Our results clearly demonstrate that CaCl 2 priming improves drought tolerance in stress-tolerant as well as drought-susceptible barley cultivars. Furthermore, we show that the beneficial effects of calcium preconditioning interact significantly with genetically determined drought tolerance.
