Tepary roots have been dug up to examine them for the presence of nodules. Nodules are the light-colored, spherical areas on the roots. They were formed by beneficial soil microbes that "set up ...

Ecuadorian bean plants rely on helpful bacteria to convert air nitrogen into plant food. A new study found diverse native bacteria groups, some more effective than common commercial products, adapting ...

Journal of Experimental Botany, Vol. 33, No. 133 (April 1982), pp. 208-214 (7 pages) The apparent nitrogenase activity of soybean root nodules is reduced approximately 70% upon nodule detachment. By ...

1. Ether extracts of nodules of bean and pea were more active in effecting negative curvatures of coleoptiles in the Avena test than those of denodulated roots. These in turn were more active than ...

Tsukuba, Japan - Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful (Figure 1), but precisely how ...

Most scientific research on the root-soil interactions of legumes focuses on rhizobia and nitrogen-fixing root nodules. However, many forms of non-rhizobia bacteria are also detected in these nodules.

Peas and other legumes develop spherical or cylindrical structures -- called nodules -- in their roots to establish a mutually beneficial relationship with bacteria that convert atmospheric nitrogen ...

WEST LAFAYETTE, Ind. – Plant breeders could theoretically increase soybean crop yields if they could control the number of nodules on plant roots since they are responsible for fixing atmospheric ...
