Abstract:

Molecular marker data (rbcLS, cox3, ITS-2) for the genus Sargassum and the monospecific genus Cladophyllum in an effort toward a comprehensive revision of the genus. Taxon names, gene sequences, and Genbank accession numbers (with collection information) are included. This dataset supports the publication: Camacho, O., Mattio, L., Draisma, S., Fredericq, S., & Diaz-Pulido, G. (2015). Morphological and molecular assessment of Sargassum (Fucales, Phaeophyceae) from Caribbean Colombia, including the proposal of Sargassum giganteum sp. nov., Sargassum schnetteri comb. nov., and Sargassum section Cladophyllum sect. nov. Systematics and Biodiversity, 13(2), 105–130.

Purpose:

To re-assess the taxonomy of Sargassum in the Caribbean from Colombia to the western tropical Atlantic using molecular marker data.

Data Parameters and Units:

File: R1.x139.000-0003_Camacho_Accession number table.txt Parameter Descriptions: Taxon name revised, Vaucher number, Collection site; Collector; Collection Date (Month Year), and GenBank accessions for the molecular analyses ITS-2, rbcLS and cox3. File: R1.x139.000-0003_Camacho_rbcLS.txt Parameter Descriptions: Vaucher number, Taxon name, and gene sequences for taxa included in the current study File: R1.x139.000-0003_Camacho_cox3.txt Parameter Descriptions: Vaucher number, Taxon name, and gene sequences for taxa included in the current study File: R1.x139.000-0003_Camacho_ITS-2.txt Parameter Descriptions: Vaucher number, Taxon name, and gene sequences for taxa included in the current study.

Methods:

The nuclear Internal Transcribed Spacer 2 (ITS-2), the chloroplast-encoded partial rbcL C spacer C partial rbcS (rbcLS), the mitochondrial Cytochrome c Oxydase subunit 3 (cox3) regions, and a mitochondrial spacer region (mtsp) were amplified. Mtsp sequences were variable and their alignment was only possible between closely related species of S. section Sargassum; so they were not included in the concatenated alignment (data available upon request to the authors).
