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 ...
Recent research on Lotus japonicus, a model leguminous plant, has unveiled that the interaction between legume roots and rhizobia is characterized by periodic gene expression with a six-hour rhythm.
Legume plants do not depend on externally supplied nitrogen, because they can form a symbiosis with nitrogen-fixing bacteria, called rhizobia. The plants recognize the nitrogen-fixing bacteria and ...
The effect of exogenous applications of gibberellins (GAs) or the growth retardant ß-chloroethyltrimethylammonium chloride (CCC) on root nodule formation and activity (C₂H₂-reduction) in soya was ...
The developmental regulators that confer the identity of N-fixing root nodules belong to a transcription factor family (LSH) more commonly associated with defining the shapes of stems, flowers and ...

WHEN a legume root is infected by the nodule organism, the formation of the young nodule is brought about by the multiplication and growth in size of the root-cells, principally in the cortex. In ...
