Soil pollution with heavy metals is an important environmental problem which affects human and food health. Neotyphodium endophytes are a group of fungi which spend their entire life cycle within the aerial portion of many grass species without any symptoms, and increase host tolerance to biotic and abiotic stresses. In this study, two genotypes of tall fescue (75 B and 75 C) in two types (infe...
AP is involved in the destruction of harmful H202. In soybean (Glycine m a x [LI Merr.) root nodules, AP initiates a sequence of coupled redox reactions (ascorbate-GSH pathway) that results in peroxide scavenging (Dalton et al., 1986). The ascorbate-GSH pathway occurs in other plant tissues and has been extensively studied in chloroplasts where photoreducing conditions lead to the production of...
Nodulin-26 (N-26) is a major peribacteroid membrane protein in soybean root nodules. The gene encoding this protein is a member of an ancient gene family conserved from bacteria to humans. N-26 is specifically expressed in root nodules, while its homolog, soybean putative channel protein, is expressed in vegetative parts of the plant, with its highest level in the root elongation zone. Analysis...
Legume root nodules are induced by N-fixing rhizobium bacteria that are hosted in an intracellular manner. These nodules are formed by reprogramming differentiated root cells. The model legumeMedicago truncatula forms indeterminate nodules with a meristem at their apex. This organ grows by the activity of the meristem that adds cells to the different nodule tissues. In Medicago sativa it has be...
apart from other aspects, desert is a natural environment and is one of the appealing terrestrial elements. putting its symbolic and fictional senses aside, the term “desert” bears mystic sense more than material sense. in addition to the worlds materialistic experiences, desert has attracted the attention of writers because it creates a kind of inner experience, which returns the individual in...
A region of DNA which determined the production of the insecticidal toxin of Bacillus thuringiensis subsp. israelensis was cloned into a derivative of a broad-host-range group IncQ plasmid vector of gram-negative bacteria. The plasmid which we constructed was transferred by conjugative mobilization into a Bradyrhizobium species that nodulates pigeon peas. In this species the construction was ma...
