Update on Ethylene Level Modulation Bacterial Modulation of Plant Ethylene Levels
A focus on the mechanisms by which ACC deaminase-containing bacteria facilitate plant growth.Bacteria that produce the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, when present either on the surface of plant roots (rhizospheric) or within plant tissues (endophytic), play an active role in modulating ethylene levels in plants. This enzyme activity facilitates plant growth especially...
متن کاملMeasurement of ACC-Deaminase Production in Halophilic, Alkalophilic and Haloalkalophilic Bacterial Isolates in Soil
Strains with 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity can cause plant growth on stress condition. In the presence of bacteria with the ability of ACC deaminase production in the rhizosphere, it is possible to convert the ethylene precursor (ACC) to α-ketobutyrate and ammonium, reducing the ethylene levels in host plants. In order to measure the power and level of A...
متن کاملthe roll of bacterial acc deaminase enzyme on the alleviation of negative effects of salinity on canola growth
abstract in this study a greenhouse experiment was conducted to evaluate the role of acc deaminase enzyme on alleviation of salinity stress of canola plant. canola plants were exposed to pseudomonas fluorescens strain p12 which contains a rhizobacter capable of producing pseudomonas fluorescens in comparison with plants exposed to mutant pm12 unable to produce the required enzyme. the mutant wa...
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 کاملEthylene and 1-Aminocyclopropane-1-carboxylate (ACC) in Plant–Bacterial Interactions
Ethylene and its precursor 1-aminocyclopropane-1-carboxylate (ACC) actively participate in plant developmental, defense and symbiotic programs. In this sense, ethylene and ACC play a central role in the regulation of bacterial colonization (rhizospheric, endophytic, and phyllospheric) by the modulation of plant immune responses and symbiotic programs, as well as by modulating several developmen...
