A NEW METHOD FOR THE QUANTIFICATION OF 1 -(MALONYLAMINO)CYCLOPROPANE- 1 - CARBOXYLIC ACID IN WATER-STRESSED PLANT TISSUES
Since the discovery of MACC as a major metabolite of both endogenous and exogenously applied ACC, it has become evident that the formation of MACC from ACC can act to regulate ethylene production in certain tissues. Hence, it was suggested that MACC could serve as an indicator of water-stress history in plant tissues. The accurate quantification of MACC in plant tissues is essential for the...
متن کاملPotential of Plant Growth Promoting Rhizobacteria and Chemical Fertilizers on Soil Enzymes and Plant Growth
The present investigation deals with the role of Plant Growth Promoting Rhizobacteria and chemical fertilizers alone or in combination on urease, invertase and phosphatase activities of rhizospheric soil and also on general impact on growth of safflower cvv. Thori and Saif-32. The PGPR (Azospirillum brasilense and Azotobacter vinelandii) were applied at 10cells/mL as seed inoculation prior to s...
متن کاملPlant Growth Promoting Rhizobacteria: A Critical Review
Plant growth-promoting rhizobacteria (PGPR) are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. Inoculation of crop plants with certain strains of PGPR at an early stage of development improves biomass production through direct effects on root and shoots growth. Inoculation of ornamentals, forest trees, vegetables, and a...
متن کاملCharacterization of Accdeaminase in Plant 361 Characterization of Acc Deaminase in Plant Growth Promoting Pseudomonas from Tannery Sludge
The plant growth promoting strains isolated from tannery sludge and charaeteri/ed is Pseudomonas strain. The plant growth promoting Pseudomonas pittidu can utilize 1-aniinocyclopropanc-l-carboxylase (ACC) as a sole nitrogen source because it possess the unusual enzyme ACC dcaminase, which hydroly/es ACC to ammonia and a-ketobutyrate. This enzyme which is though to be intimately involved in the ...
متن کاملPlant growth promoting Rhizobacteria: An overview
Numerous species of soil bacteria which flourish in the rhizosphere of plants, but which may grow in, on, or around plant tissues, stimulate plant growth by a plethora of mechanisms. These bacteria are collectively known as PGPR (plant growth promoting rhizobacteria).Of the microorganisms that parasitize on nematodes and reduce nematode populations by antagonistic behaviour, bacteria hold an im...
