Abstract:
Symbiotic diatom-diazotrophic cyanobacteria association (DDA) of Rhizosolenia hebetata and Rhizosolenia formosa with
endosymbiotic cyanobacteria Richelia intracellularis was noticed and documented for the first time during a bloom of the
cyanobacterium Trichodesmium erythraeum in the oligotrophic shelf waters along Kochi and Mangalore transects, southeastern
Arabian Sea (SEAS), during spring intermonsoon (April 2012). Although the host is frequently seen, the symbiont is rarely reported
in the Indian EEZ. The presence of nitrogen-fixing symbiotic association of Rhizosolenia-Richelia along with Trichodesmium
erythraeum highlights the significance of DDAs on the nutrient and energy budgets of phytoplankton in the oligotrophic
environments of the Arabian Sea during spring intermonsoon
