Promotion of Wheat Growth under Salt Stress by Halotolerant Bacteria Containing ACC deaminase
Salinity is a major abiotic stress that reduces crop productivity in arid and semiarid soils. About 25% of the country's arable land is affected by different levels of salt. A considerable part of this land is under wheat cultivation each year as the country's most important crop. ACC deaminase producing bacteria increase plant resistance to stress condition by reducing stress ethylene in a var...
متن کاملExpression of an exogenous 1-aminocyclopropane-1-carboxylate deaminase gene in Sinorhizobium meliloti increases its ability to nodulate alfalfa.
1-Aminocyclopropane-1-carboxylate (ACC) deaminase has been found in various plant growth-promoting rhizobacteria, including rhizobia. This enzyme degrades ACC, the immediate precursor of ethylene, and thus decreases the biosynthesis of ethylene in higher plants. The ACC deaminase of Rhizobium leguminosarum bv. viciae 128C53K was previously reported to be able to enhance nodulation of peas. The ...
متن کاملPromotion of Growth and Modulation of As- Induced Stress Ethylene in Maize by As- Tolerant ACC Deaminase Producing Bacteria
One of the major pollutants in the environment is arsenic (As). Due to the toxic effects of As to all organisms, its remediation is necessary. Conventional technologies used in the remediation of As contaminated soils are expensive and may even compromise the structure of the soil. An attractive alternative is phytoremediation, which is the use of plants which can take up the contaminant in the...
متن کاملan evaluation of auxin hormones and acc deaminase production ability by iranian soils rhizobial strains and the effects of superior strains application on plant growth characteristics
it,s nowadays proved that one can, from among many strains of rhyzobium species, find those which, in addition to high efficiency in n2 fixation, can positively affect such processes as plant growth (e.g. through production of plant growth hormones). such strains can be useful not only to their special host, but also to other plants as well as to strategic products as grains. soil biotechnology...
متن کاملACC (1-aminocyclopropane-1-carboxylate) deaminase activity, a widespread trait in Burkholderia species, and its growth-promoting effect on tomato plants.
The genus Burkholderia includes pathogens of plants and animals and some human opportunistic pathogens, such as the Burkholderia cepacia complex (Bcc), but most species are nonpathogenic, plant associated, and rhizospheric or endophytic. Since rhizobacteria expressing ACC (1-aminocyclopropane-1-carboxylate) deaminase may enhance plant growth by lowering plant ethylene levels, in this work we in...
