Sherry Krayesky-Self Ph.D. discovered and documented with SEM, TEM and Fluorescence microscopy previously unrecognized benthic life history stages of the toxic, bloom-forming dinoflagellate Prorocentrum lima and the bloom-forming haptophyte Ochrosphaera verrucosa. These life stages were found residing endolithically inside calcium carbonate-lined cell lumens of crustose coralline algae (CCA) Lithothamnion rhodoliths. The taxonomic identity of these life history stages new to science was confirmed by whole genome amplification on single cells and subsequent cob1 sequencing for dinoflagellates, and tufA and 18S sequencing for haptophytes. Endolithic stages of a new sp. of Rhodosorus, a unicellular red algal genus were also identified. Dr. Self, her colleagues and several undergraduate researchers continue to explore this new association found between macro- and micro- algae in the North West Gulf of Mexico.
