Cultures

Culture strains of Coccolithophores and other Haptophytes

Cultures are a prime resource for research on coccolithophores and other haptophytes. This page provides a list of haptophyte cultures in the Roscoff Culture Collection (RCC). The RCC collections are listed since they are the largest and most comprehensive coccolithophore culture collection, and because metadata includes links to GENBANK sequence data. The very extensive haptophyte holdings of the Roscoff collection reflects the facts that they have been developed by Dr. Ian Probert, a specialist on coccolithophores, and that they incorporate the collections developed by the Caen research group (Jacqueline Fresnel and Chantal Billard) and during the CODENET project. The collection also include cultures isolated by other coccolithophore specialists, notably including Kyoko Hagino and Peter von Dassow.

Other culture collections with significant holdings of haptophytes include:

The NIES culture collection in Tsukuba, Japan
The NCMA collection at the Bigelow Lab, Maine, USA - formerly the CCMP
The Norwegian Culture Collection of Algae (NORCCA), at NIVA, Oslo, Norway. (also incorporating cultures from the former Scandinavian Culture Collection in Copenhagen).

At the time of writing (March 2020) none of these collections hold any coccolithophore species not also present in Roscoff but the Oslo collection, in particular, does have some additional Chrysochromulina species.

GENBANK: The prime repository for sequence data is GENBANK, since deposition of sequences is required for publication in most journals. Most taxonomically constrained sequence data for haptophytes comes from strains so there is a rather close correspondence in coverage between strains and sequences. The RCC pages include links to sequences derived from those strains. Alternatively the GENBANK taxonomy browser can be directly accessed.

Table of cultured species in the RCC

This table lists all taxa for which there are identified strains in the Roscoff Culture Collection. The listing is based on a search of the RCC database made in March 2020, updated November 2022. Some other species may be in culture but are not yet publically available, and listing of a species here is no guarantee either that it is still in culture or that it is freely available. The RCC database provides a listing of available strains for each species together with data on when and where they were collected and, when available, links to GENBANK sequences derived from them.
