A2 nitrogen fixation + denitrification
hi, is this right?
nitrogen fixation by root nodules takes the nitrogen gas from the soil and converts it into ammonium compounds. This (after nitrification) allows plants to take up nitrogen in the form of nitrates.
denitrification occurs in anaerobic conditions and converts the nitrates which aren't taken up by plants (due to lack of oxygen so plants don't survive) into nitrogen gas. The nitrogen gas then returns to the cycle.
thanks

I think its that denitrifing bacteria in the soil convert the excess nitrates into nitrites and then nitrogen gas so that the nitrogen can be put back into the cycle. Otherwise in waterlogged soil, there would be a load of nitrogen in the form of nitrates that wouldn't be used. In effect I think its the opposite of nitrification.
So, plants uptake nitrate and convert it with nitrate reductase and nitrite reductase down to ammonia. Plants with symbiotic bacteria (like Leguminosae http://www.biolib.cz/en/taxon/id3273/) can convert nitrogen to ammonia.
This ammonia is than incorporated into amino acids like Glc and Gln by GS-GOGAT system.

Cis or trans? That's what matters.

but they do make it. but somehow if they can use the NH3 directly then won't it be helpful.
what do you think can be done so this is possible
just imagine by genetic engineering and transformation you get the changes you are willing to do then what mechanism could be used so as to make it possible
was a bit confusing.

it isn't what you do that matters but it is how you do it
