Viruses pose a serious threat to the sustainable production of economically important crops around world. In past 20 years, potato virus Y (PVY) emerged as relatively new and very problem in potatoes, even though it is oldest known plant virus. Multiple strains cause various symptoms on leaves tubers resulting yield reduction poor-quality tubers. Consequently, would be interesting learn what ca...

Silicon (Si) has been known to augment plant defense against biotic and abiotic pressures. Maize (Zea maize L.) is classified as a Si accumulator and is relatively susceptible to alkaline stress. In this study, seeds of maize were grown in pots and exposed to various concentrations of Na2CO3 (0, 25, 50, and 75 mM) with or without 1.5 mM Si in the form of sodium metasilicate Na2O3Si.5H2O for 25 ...

UNLABELLED The enzymatic activity of Escherichia coli endo-RNase III determines the stability of a subgroup of mRNA species, including bdm, betT, and proU, whose protein products are associated with the cellular response to osmotic stress. Here, we report that the stability of proP mRNA, which encodes a transporter of osmoprotectants, is controlled by RNase III in response to osmotic stress. We...

In the present study we attempted to correlate the structure and function of the cry11a (72 kDa) and cry4a (135 kDa) proteins of Bacillus thuringiensis var israelensis. Homology modeling and secondary structure predictions were done to locate most probable regions for finding helices or strands in these proteins. The JPRED (JPRED consensus secondary structure prediction server) secondary struct...

Polyamines (PAs) are plant growth regulators that attenuate the destructive impacts of water deficit on sesame plants, particularly in arid regions under abrupt climate change. Limited information is available physiological, biochemical, anatomical, and agronomic responses to exogenous application PAs field conditions. Thus, a two-season trial was carried out assess impact exogenously sprayed s...

γ-Aminobutyric acid (GABA) has high physiological activity in plant stress physiology. This study showed that the application of exogenous GABA by root drenching to moderately (MS, 150 mM salt concentration) and severely salt-stressed (SS, 300 mM salt concentration) plants significantly increased endogenous GABA concentration and improved maize seedling growth but decreased glutamate decarboxyl...

Abiotic stresses such as drought, heat, cold, nutrient deficiency, excess salt and hazardous metals can hamper plantgrowth development. Intensive agriculture of only a few major staple food crops that are sensitive intolerant to environmental has led an agrarian crisis. On the other hand, nutritionally rich, gluten free stress tolerant plants like millets neglected underutilized. Millets sustai...

The intracellular accumulation of organic compatible solutes acting as osmoprotectants, such as polyols, is an essential response mechanism of several plants to drought and salinity. In Olea europaea a mannitol transport system (OeMaT1) has been previously characterised as a key player in plant response to salinity, and here, heterotrophic sink models, such as olive suspension-cultured cells an...

In solution, the correlation time of the overall protein tumbling, tau(R), plays a role of a natural dynamics cutoff-internal motions with correlation times on the order of tau ( R ) or longer cannot be reliably identified on the basis of spin relaxation data. It has been proposed some time ago that the 'observation window' of solution experiments can be expanded by changing the viscosity of so...

Choline oxidase catalyzes the two-step oxidation of choline to glycine betaine, one of limited osmoprotectants, with the formation of betaine aldehyde as an enzyme bound intermediate. Glycine betaine accumulates in the cytoplasm of plants and bacteria as a defensive mechanism to withstand hyperosmolarity and elevated temperatures. This makes the genetic engineering of relevant plants which lack...
