Hairy Roots, their Multiple Applications and Recent Patents

open access: yesRecent Patents on Biotechnology, 2012
In the last years, hairy root (HR) cultures are gaining attention in the biotechnology industry. This particular plant cell culture derives from explants infected with Agrobacterium rhizogenes. They constitute a relatively new approach to in vitro plant biotechnology and modern HR cultures are far away from the valuables findings performed by Philip R.

Effect of Different Strains of and Nature of Explants on Hairy Root Culture with Special Emphasis on Root Biomass and Plumbagin Production

open access: yesNatural Product Communications, 2010
The aim of the present study was to determine the effect of three strains of Agrobacterium rhizogenes (ATCC 15834, A 4 and LBA 9402) and the nature of explants (leaf and stem) on hairy root induction, growth and plumbagin production in Plumbago indica ...
