The role of morpho-physiological attributes along with the antioxidant potential Stipagrostis plumosa L. populations collected from arid regions in adaptability to aridity was evaluated. Root shoot length, chlorophyll, carotenoids, and organic osmolytes (total free amino acids, total soluble proteins, glycinebetaine, proline) increased more activities enzymes (APX, CAT, POD, SOD). fresh:dry wei...

Lentil (Lens culinaris, Medik.), an accessible low-cost high-quality protein form for many people, is a salt-sensitive legume, which already at electrical conductivity (EC) of 3 dS/m (~30 mM NaCl) has yield loss about 90% compared to other crops. Identifying salinity-tolerant lentil germplasm nowadays primary importance ensuring the production superfood and sustainability industry. In this stud...

Abstract Aims The survival and ecological distribution of plants in arid habitats are mainly conditioned by water availability physiological adaptations to withstand drought. In the present study, we have compared responses drought two Retama raetam (retama) subspecies from Tunisia, one them living under desert climate (subsp. raetam) other growing on coast bovei). Methods To physiologically ch...

Abstract Drought stress is an unavoidable challenge limiting plant production and quality. Stigmasterol a potential compound for protection improvement productivity under drought. Thus, the effects of using stigmasterol as exogenous treatment on improving growth sunflower grown drought were studied. A pot experiment was carried out at two summer seasons, foliar 0, 100, 200, 300 mg L −1 plants d...

Introduction: Streptomyces manage the osmotic stress by collecting compatible solutes or osmolytes. Ectoine, 1,4,5,6-tetrahydro-2-methyl-4-pyrimidine carboxylic acid, and 5-hydroxyectoine are among the most common osmolytes of this bacteria and have an active role in protecting the genetic material of this microorganism as well as providing resistance to environmental pressures. In this researc...

Choline and glycine betaine (GBT) are utilized as osmolytes to counteract osmotic stress, but also constitute important nutrient sources for many marine microbes. Bacterial catabolism of these substrates can then lead the production climate active trace gases such methylamine methane. Using radiotracers, we investigated prokaryotic choline/GBT uptake determined biotic abiotic factors driving pr...
