Osmotic stress response

Competition and environmental stress are crucial factors for structuring plant population in natural habitats. Cyperus arenarius, a sedge of coastal sand dunes habitat, is a suitable species for coastal restoration and dune stabilization, but how salinity and plant density interact in affecting its growth is still unknown. Here, growth, survival, and physiological responses of C. arenarius to salinity (sea-salt) and plant density were investigated.

Pathogenesis-related proteins (PR-proteins) are induced in response to environmental stresses such as osmotic and drought stress, wounding, microbial infections and treatment with specific plant hormones and elicitors. These proteins are classified into several groups (PR-1 through PR-17) based on their amino acid sequence and biochemical functions. The present study focuses on prediction, isolation, over-expression and analysis of the antifungal activities of the thaumatin-like proteins (i.e. PR-5) in the model legume M. truncatula var. truncatula. Analysis of M.

Salinity is an important abiotic stress that influences the physiological and metabolic activity, reproduction, growth and development of marine fish. It has been suggested that half-smooth tongue sole (Cynoglossus semilaevis), a euryhaline fish species, uses a large amount of energy to maintain osmotic pressure balance when exposed to fluctuations in salinity. To delineate the molecular response of C. semilaevis to different levels of salinity, we performed RNA-seq analysis of the liver to identify the genes and molecular and biological processes involved in responding to salinity changes.

To control the osmotic pressure in the body, physiological adjustments to salinity fluctuations require the fish to regulate body fluid homeostasis in relation to environmental change via osmoregulation. Previous studies related to osmoregulation were focused primarily on the gill; however, little is known about another organ involved in osmoregulation, the kidney.

The fungicide fludioxonil over-stimulates the fungal response to osmotic stress, leading to overaccumulation of glycerol and hyphal swelling and bursting. Fludioxonil-resistant fungal strains that are null-mutants for osmotic stress response genes are easily generated through continual sub-culturing on sub-lethal fungicide doses.

Chickpea (Cicer arietinum L.) is the second most widely grown pulse and drought (limiting water) is one of the major constraints leading to about 40–50% yield losses annually. Dehydration responsive element binding proteins (DREBs) are important plant transcription factors that regulate the expression of many stressinducible genes and play a critical role in improving the abiotic stress tolerance.

Salinity is one of the most aggressive environmental stresses that hamper crop productivity worldwide. Increased salt concentration in soil reduces plants ability to take up water. It also reduces nutrients availability, uptake and transport, and there distribution resulting nutritional imbalance in plant. The Salt Overly Sensitive (SOS) signalling pathway is crucial to mediate cellular signalling and to maintain ion homeostasis under salinity stress. Many HKT family plasma membrane transporters play an essential role in salt tolerance mechanism by regulating Na+ and K+ transportation.

Plant growth and development are adversely affected by salinity- a major environmental stress that limits agricultural production. Chickpea (Cicer arietinum L.) is sensitive to salinity that affects its yield and there is need to identify the tolerant genotypes. In order to evaluate the effect of soil salinity, a pot experiment with two chickpea genotypes was carried out under screen house conditions.

Wild soybean (Glycine soja) is a highly adaptive plant species which can grow well in saline-alkaline soils. In soybean genome, there exist about 140 HD-Zip (Homeodomain-leucine Zipper) genes. HD-Zip transcription factor family is one of the largest plant specific superfamilies and plays important roles in response to abiotic stresses.

Salinity tolerance is a physiologically multi-faceted trait attributed to multiple mechanisms. Three barley (Hordeum vulgare) varieties contrasting in their salinity tolerance were used to assess the relative contribution of ionic, osmotic and oxidative stress components towards overall salinity stress tolerance in this species, both at the whole-plant and cellular levels.

Reception of and response to exogenous and endogenous osmotic changes is important to sustain plant growth and development, as well as reproductive formation. Hyperosmolality-gated calcium-permeable channels (OSCA) were first characterised as an osmosensor in Arabidopsis and are involved in the perception of extracellular changes to trigger hyperosmolality-induced [Ca2+]i increases (OICI).
