Gene Details:

  • Gene ID: Sb04g005210
  • Gene Symbol: Bmr2
  • Gene Name: Brown midrib2
  • Genome:
  • Species: Sorghum bicolor

Functional Descriptions:

  • Brown midrib2 (Bmr2) encodes the major 4-coumarate:coenzymeA ligase involved in lignin biosynthesis in sorghum.
  • Bmr2 is the most highly expressed 4CL in sorghum stems, leaves and roots, both at the seedling stage and in pre-flowering plants, but the products of several paralogs also display 4CL activity and compensate for some of the lost activity.
  • The contribution of the paralogs varies between developmental stages and tissues. Gene expression assays indicated that Bmr2 is under auto-regulatory control, as reduced 4CL activity results in over-expression of the defective gene.
  • We show here that the Bmr2 mutation is located in one of the sorghum 4CL genes, and that the Bmr2 mutant phenotype provides evidence for a major but not exclusive role for this 4CL gene in lignification.
