Aluminum (Al) stress in acid soils is one of the major factors limiting crop productivity. ATP binding cassette (ABC) transporters have numerous roles in plants, but the link between ABCB protein subfamily and plant Al tolerance is still elusive. Here, we identified and characterized a novel
Bacteria are able to communicate with each other and sense their environment in a population density dependent mechanism known as quorum sensing (QS). N-acyl-homoserine lactones (AHLs) are the QS signaling compounds of Gram-negative bacteria which are frequent colonizers of rhizospheres. While
Economical and bio-friendly approaches are needed to remediate dye-contaminated wastewater from various industries. In this study, a novel bacterial strain capable of decolorizing triarylmethane dyes was isolated from a textile wastewater treatment plant in Greece. The bacterial isolate was
The purpose of this study was development of the optimal conditions for the inertization of the polluted marine sediments using groundwater treatment sludge highly enriched in iron and aluminum. For that purpose fine-grained sediment (>85% clay and silt fraction) highly enriched in copper and zinc
Differential display was used to isolate cDNA clones showing differential expression in response to ABA, drought and cold in barley seedling shoots. One drought-regulated cDNA clone (DD12) was further analyzed and found to encode a branched-chain amino acid aminotransferase (HvBCAT-1). A genomic
The feasibility of decontaminating creosote-treated wood (CTW) by co-composting with agricultural wastes was investigated using two bulking agents, grass cuttings (GC) and broiler litter (BL), each employed at a 1:1 ratio with the matrix. The initial concentration of total polycyclic aromatic
Aluminum (Al) toxicity is a major limiting factor for plant production in acid soils. Wild barley germplasm is a treasure trove of useful genes and offers rich sources of genetic variation for crop improvement. Al-stress-hydroponic-experiments were performed, and the physiochemical characteristic of
Barley (Hordeum vulgare L.) is a multipurpose crop that can be harvested as grain or cut prior to maturity for use as forage. Fusarium head blight (FHB) is a devastating disease of barley that reduces quality of grain. FHB can also result in the accumulation of mycotoxins such as
The role of nitric oxide (NO) as a key molecule in the signal transduction pathway of a biotic stress response has already been described. Recent studies indicate that it also participate in the signaling of abiotic stresses. In the present study, we showed the altered expression of stress
L-carnitine is a fundamental ammonium compound responsible for energy metabolism in all living organisms. It is an oxidative stress regulator, especially in bacteria and yeast and lipid metabolism in plants. Besides its metabolic functions, l-carnitine has detoxification and antioxidant roles in the
Barley (Hordeum vulgare) is one of the most important cereals in many developing countries where drought stress considerably diminishes agricultural production. Glutathione S-transferases (GSTs EC 2.5.1.18) are multifunctional enzymes which play a crucial role in cellular detoxification and
Aluminum (Al) toxicity is a major stress factor limiting crop productivity in acid soil. Although there is great genotypic variation in tolerance to Al toxicity, the underlying molecular mechanisms are poorly understood. Here, we report that, in barley (Hordeum vulgare), the fourth largest cereal
Medicinal plants have played a major role as a functional food and pharmacological source of active substances. Barley grass (BG) is young green barley leaves. It is the young grass of the common barley plant Hordeum vulgare L. of the family Poeaceae (Graminae). It is a type of green grasses, and
This work was designed to assess the potential role of silicon dioxide nanomaterial (nano-SiO2) in enhancing barley's tolerance to nickel oxide nanomaterial (nano-NiO). For this purpose, plants were grown for 14days under nano-NiO (120mgkg-1) single and co-exposure with nano-SiO2 (3mgkg-1). The
Although barley (Hordeum vulgare L.) is considered a salt tolerant crop species, productivity of barley is affected differently by ionic, osmotic, and oxidative stresses resulting from a salty rhizosphere. The current study was conducted to elucidate the mechanism of salt tolerance in two barley
