Question

How does soybean export fixed nitrogen?

Answer 1

Soybean export fixed nitrogen by:

1. Ureides (degraded urea) are used to carry nitrogen out of some legumes nodules, including soybeans, and back into their aging organs.
2. Their nitrogen-to-carbon ratio is high.
3. Through a symbiotic association with nitrogen-fixing bacteria that live in root nodules, soybean plants may acquire atmospheric nitrogen.
4. The ureides, allantoin, and allantoic acid, which are also the main long-distance nitrogen transport forms from nodules to the shoot in soybean, are the by-products of fixation.
5. It is also moved by the xylem root system to shoots.
