Crops like peas, beans and alfalfa, which carry their own nitrogen-fixing bacteria on root nodules, account for 32 million to 53 million metric tons.

The members of this tribe have a distinctive root nodule morphology, often referred to as an " aeschynomenoid " or " dalbergioid " nodule.
43.
While root nodules are typically found on buried roots, " P . macroloba " individuals growing in swampy areas produce nodules on aerial roots.
44.
The patentee discovered that there are strains of each species of root nodule bacteria which do not exert a mutually inhibitive effect on each other.
45.
Some trees such as the alders ( " Alnus " species ) have a actinorhizal root nodules on their roots in which the bacteria live.
46.
*Leguminous green manures such as clover and vetch contain nitrogen-fixing symbiotic bacteria in root nodules that fix atmospheric nitrogen in a form that plants can use.
47.
The presence of rhizobia-containing root nodules is usually associated with nitrogen fixation in legumes; this was the first record of root nodules in a monocotyledonous tree.
48.
The presence of rhizobia-containing root nodules is usually associated with nitrogen fixation in legumes; this was the first record of root nodules in a monocotyledonous tree.
49.
It hosts bacteria known as rhizobia that form root nodules, where they make nitrogen available in organic form and thus help the plant grow in poor soils.
50.
The most distinctive characteristics that allow rhizobia to be distinguished apart are the rapidity of their growth and the type of root nodule that they form with their host.
