Limited P availability in several agricultural areas is one of the key challenges facing current agriculture. Exploiting P-solubilizing bacteria (PSB) has been an emerging bio-solution for a higher rhizosphere P-availability, meanwhile the above- and below-ground interactions that PSB would trigger remain unclear over plant growing stages. We hypot...

Question
For in vitro culture of arbuscular we use either transformed roots or micropropagated plants.
is it possible to use simple germinated seeds in pétri dishes system (filled with synthetic medium). Because there is no mention of that in the litterature and I wonder why.
Question
Is there any company using bioreactors to mass produce arbuscular mycorrhiza, or the technology is just at the stage of patents and theory.
