We report the growth promoting potential of Piriformospora indica
, which is a newly discovered Arbuscular mycorrhiza
-like fungus. It is a facultative symbiont and unlike arbuscular mycorrhizal fungi, it can be cultured in vitro. Adhatoda vasica
is a medicinal plant. Rapid proliferation of roots was recorded in A. vasica
withan important root colonization estimated to 95% after 6 months. P. indica
improved growth of A. vasica
. This association forms a new host-symbiont combination.
