Engineering cereal plants to produce a signal to communicate with and control the bacteria on their roots could potentially enable them to take advantage of the growth-promoting services of those bacteria, including nitrogen fixation.
Some research groups are interested in extending the symbiosis (https://aem.asm.org/content/82/13/3698) by genetically engineering crops such as corn and wheat so that they can reap the benefits of nitrogen fixation, which only some plants, including legumes, can do now.
Key Words: Cyanobacteria, Nitrogen Fixation, GC-MS, Amino acids.
Furthermore the production of IAA influences nif gene expression which regulates nitrogen fixation by nitrogenase enzyme (Defez et al, 2017).
Pannell and Falconer (1988) identified two components of the benefits of nitrogen fixation: (1) reduction in the economically optimal rate of nitrogen fertiliser and (2) contributing to an increase in yield due to biologically fixed nitrogen that does not act as a direct substitute for nitrogen fertiliser, perhaps because it becomes available to crops more slowly as biological material breaks down.
The inoculation of the common bean with a recommended rhizobium strain in combination with the application of Mo contributed to improving biological nitrogen fixation and grain dry weight in two common bean cultivars.
Atmospheric nitrogen fixation takes place when enormous lightening energy breaks N2 into nitric oxide (N[O.sub.2]) and then combines it with oxygen ([O.sub.2]) farming nitrate (N[O.sub.3]) that is carried into the earth along with rainfall.
Rhizobia are recognized for their talent to carry out symbiotic nitrogen fixation by creating nodules on the roots of legumes.
The increase in cultivation of leguminous pulses and oilseeds will also have additional environmental benefits as these crops are less water consuming and help in nitrogen fixation in the soil.
It is an attempt to increase nitrogen fixation and the yield at all the sites of harsh climate.
