Identification of cyanobacterial association from the roots of the terrestrial orchid, Spathoglottis plicata Blume

Two cyanobacterial species belonging to the family Oscillatoriaceae are reported from the underground roots of the terrestrial orchid, Spathoglottis plicata. Cyanobacterial community on the orchid roots depended on the conditions of the plant growth. Very little is known about the species level taxonomic descriptions of orchid associated cyanobacteria and hence our study is the first report on the species level cyanobacterial association with the terrestrial orchid, Spathoglottis plicata.
