Description 453-457
Symbiotic association of
heterocystous cyanobacterium, Richelia
intracellularis Schmidt with oceanic centric diatom, Rhizosolenia hebetata is
reported from the Palk Bay, southeast coast of India. One to six
trichomes of R. intracellularis were
occluded inside the periplasmic space of R.hebetata, with their
prominent heterocyst pointing towards the valve of the host. Each of these
trichomes had 14 to 23 vegetative cells caped by a terminal heterocyst enriched
with the nitrogenase
enzyme. Density of Rhizosolenia containing R. intracellularis ranged
between 120 and 260 cells L-1, and present uniformly in the water
column. R. intracellularis is a diazotroph, can contribute substantially
to the N2 budgets thereby, promoting a different food web
in the Palk Bay.
