Abstract
A method of plant tissue culture which comprises culturing a tissue or an organ of a plant, a part of the same or cultured cells in a medium containing a culture filtrate and/or an extract of a photosynthetic procaryotic microorganism. Such a culturing method effectively proliferates the plant tissues and cultured cells, and also promotes the formation of adventive embryos, regeneration of the plant body and production of useful substances formed by that plant. Strains of cyanobacteria or photosynthetic bacteria are preferably used as the photosynthetic procaryotic microorganism.
