Isolation and Characterization of a DNA Fragment Containing Genes for Mimosine Degradation from Rhizobium Sp. Strain TAL1145

  • Chapter
Highlights of Nitrogen Fixation Research

Abstract

The rhizosphere of plants is a highly complex and dynamic ecosystem due to the continuous supply of organic material from the plants as root exudates. We found that mimosine, a toxic free amino acid, is present in the root exudates of the tree legumes of genus Leucaena. Mimosine is found in large quantities in the seeds, foliage and roots of Leucaena spp. It has general antimitotic activity that inhibits the growth of certain microorganisms but it also enhances the growth of others that can utilize it as a putriept source Some Rhizobium strains isolated from the podules of leucaena trees.
