Leghaemoglobin
EN
Leghaemoglobin is a nitrogen or oxygen carrier, because naturally occurring oxygen and nitrogen interact similarly with this protein; and a hemoprotein found in the nitrogen-fixing root nodules of leguminous plants. It is produced by legumes in response to the roots being colonized by nitrogen-fixing bacteria, termed rhizobia, as part of the symbiotic interaction between plant and bacterium: roots not colonized by Rhizobium do not synthesise leghaemoglobin.
In L. japonicus, this protein is formed in the root nodules, where it ensures the supply of oxygen in the case of minimal partial pressure on free oxygen in tissues.
