Seed germination is generally the critical step in seed establishment and thus determination of successful crop production. This study was focused at examination biochemical parameters effected by low water potential which generated polyethylene glycol (PEG) 6000 mannitol, related to drought stress growth Waha durum wheat genotype. Two tests were carried out a chamber; first comprises into Petr...

Naproxen is a poor water soluble, non-steroidal analgesic and anti-inflammatory drug. The enhancement of oral bioavailability of poor water soluble drugs remains one of the most challenging aspects of drug development. Although salt formation, solubilization and particle size reduction have commonly been used to increase dissolution rate and thereby oral absorption and bioavailability of low wa...

Drought stress is a serious threat to the germination of plant seeds and growth seedlings. Melatonin has been proven play an important role in alleviating stress. However, its effect on seed under drought conditions still poorly understood. Therefore, we studied effects melatonin rice physiological characteristics Rice were treated with different concentrations (i.e., 0, 20, 100, 500 μM) was si...

Drought is a major limiting factor of Brassica napus (rapeseed) and potassium (K) plays important roles in rapeseed drought tolerance. Previous studies have reported that cultivars characterized by different K status showed contrasting However, the molecular mechanism underlying tolerance remains unclear. In this study, comparative transcriptome analysis was conducted between drought-tolerant c...

As a gaseous molecule, hydrogen sulfide (H2S) has been recently found to be involved in plant responses to multiple abiotic stress. In this study, salt (150 and 300 mM NaCl), osmotic (15% and 30% PEG6000) and cold (4 °C) stress treatments induced accumulation of endogenous H2S level, indicating that H2S might play a role in bermudagrass responses to salt, osmotic and cold stresses. Exogenous ap...

Protein-protein interactions are important for the molecular understanding of the biological processes of proteins. The dimerization of bZIPs (basic leucine zipper proteins) is involved in modifying binding site specificities, altering dimer stability, and permitting a new set of specific protein-to-protein interactions to occur at the promoter. In the present study, we studied the whether ThbZ...

Drought is one of the most important natural phenomenon which affects on plant growth. Alfalfa (Medicago sativa L.) is an essential fodder product which has extensive and depth roots system, this advantage enables the plant to tolerate long term drought without any damage to its regrowth process. In order to measure germination percentage and rate, root and shoot growth of 6 alfalfa cultivars (...

The WRKY transcription factors have been reported to be involved in various plant physiological and biochemical processes. In this study, we successfully assembled 10 unigenes from expressed sequence tags (ESTs) of wheat and designated them as TaWRKY44-TaWRKY53, respectively. Among these genes, a subgroup I gene, TaWRKY44, was found to be upregulated by treatments with PEG6000, NaCl, 4°C, absci...
