""'Microbacterium azadirachtae " "'is a Gram-positive, non-spore-forming and motile bacterium from the genus of Microbacterium which has been isolated from the rhizoplane of the plant Azadirachta indica from the Botanical Garden of Coimbatore in India . " Microbacterium azadirachtae " can promote plant growth by producing phytohormones.

This medium nicely lends itself to the application of specific concentrations of phytohormones etc . to induce specific growth patterns in that one can easily prepare a solution containing the desired amount of hormone, add it to the known volume of GM, and autoclave to both sterilize and evaporate off any solvent that may have been used to dissolve the often-polar hormones.

With the availability of molecular genetics in Arabidopsis and rice the mutant genes responsible ( " reduced height ( rht ) ", " gibberellin insensitive ( gai1 ) " and " slender rice ( slr1 ) " ) have been cloned and identified as cellular signalling components of gibberellic acid, a phytohormone involved in regulating stem growth via its effect on cell division.
