Transformed root

Agrobacterium rhizogenes can induce hairy root in many of the dicot plant species. Hairy roots are obtained after successful transformation of plant species by T-DNA from a plasmid of Agrobacterium rhizogenes. Plants regenerated from the hairy root have different phenotypic characters. It has interesting growth capacities owing to the profusion of lateral roots. This growth can be analysed in detailed exponential model when the number of generations of lateral roots become large. Thus this feature has led to considerable attention of plant biotechnologists to produce root-specific secondary compounds.
