Glomalin is a glycoprotein identified in and extracted from cell walls of hyphae and spores of Glomeral fungi. It deposites on soil particles and acts as a glue which leads to the formation and stabilization of soil aggregates. Water deficit stress by affecting mycorrizal symbiosis can alter glomalin production. This study was conducted as a factorial experiment arranged in a completely randomi...

deficit of oil seeds and high volume of oil imports in iran, and limitation of water sources against production of many oil seed crops, demonstrate the importance of detection tolerant species and cultivars for stressful conditions and their most sensitive growth stages to saline stress. in order to study response of spring safflowers (carthamus tinctorius l.) genotypes to disruption irrigation...

The effects of irrigation, dry farming and drought treatments on the activities of antioxidant enzymes including superoxide dismutase, ascorbate peroxidase, catalase and peroxidase in barley leaves at different generative growth stages under field conditions were investigated. Three senescence parameters including chlorophyll, total soluble protein and rubisco large subunit protein loss, were a...

In order to study and evaluate the drought stress indices in surface irrigation by furrow method on grain yield, the yield components and water use efficiency, an experiment was conducted at Behbahan Agricultural Research Station in 2014-16. The experiment was conducted as a split plot in a randomized complete block design with 4 replications. Irrigation at two levels (irrigation after 100 and ...

Plants respond to dehydration stress and tolerate water-deficit status through complex physiological and cellular processes. Many genes are induced by water deficit. Abscisic acid (ABA) plays important roles in tolerance to dehydration stress by inducing many stress genes. ABA is synthesized de novo in response to dehydration. Most of the genes involved in ABA biosynthesis have been identified,...

The sucrose non-fermenting 1-related protein kinase 2 (SnRK2) family members are plant unique serine/threonine kinases which play a key role in cellular signaling in response to abiotic stresses. The three SnRK2 members including SRK2D, SRK2I and SRK2E are known to phosphorylate major abscisic acid (ABA) responsive transcription factors, ABF2 and ABF4, involved in an ABA-dependent stress signal...

This study looked at regulated deficit irrigation (RDI) on leafhoppers in the genus Erythroneura (Erythroneura elegantula Osborn, or western grape leafhopper, and Erythroneura variabilis Beamer) (Hemiptera: Cicadellidae), which are serious pests of cultivated grape (Vitis vinifera L.) in California. RDI is an irrigation strategy that reduces irrigation during a critical point in the phenology o...

Changes in water-soluble carbohydrates were examined in the leaves of the resurrection plant Xerophyta viscosa under conditions of water deficit. Sucrose and raffinose family oligosaccharides (RFOs), particularly raffinose, increased under these conditions, with the highest concentrations evident at 5% relative water content [RWC; 23.5 mg g(-1) dry weight (DW) and 17.7 mg g(-1) DW, respectively...
