binomial_authority = (Riker et al. 1930) Conn 1942Agrobacterium rhizogenes is a
Gram negative soil bacterium. In therhizosphere , plants may suffer from wounds by soilpathogens or other sources. This leads to the secretion ofphenolic compounds likeacetosyringone which have chemotactic effects that attract the bacteria. Under such conditions, certain bacterial genes are turned on leading to the transfer of itsT-DNA from itsRi plasmid into the plant through the wound. After integration and expression, "in vitro" or under natural conditions, the hairy rootphenotype is observed.The hairy roots are grown "in vitro" in
bioreactor s to study their soil interaction with other pathogens likefungi andnematodes . It has also led to the commercial production of certain metabolic compounds that the plant is known to secrete, especially in regard to the medicinal plants where a larger root biomass is obtained.References
