Abstract:
Although the Gelidiales are economically important marine red algae producing agar and agarose, the
phylogeny of this order remains poorly resolved. The present study provides a molecular phylogeny
based on a novel marker, nuclear-encoded CesA, plus plastid-encoded psaA, psbA, rbcL, and
mitochondria-encoded cox1 from subsets of 107 species from all ten genera within the Gelidiales.
Analyses of individual and combined datasets support the monophyly of three currently recognized families,
and reveal a new clade. On the basis of these results, the new family Orthogonacladiaceae is
described to accommodate Aphanta and a new genus Orthogonacladia that includes species previously
classified as Gelidium madagascariense and Pterocladia rectangularis. Acanthopeltis is merged with
Gelidium, which has nomenclatural priority. Nuclear-encoded CesA was found to be useful for improving
the resolution of phylogenetic relationships within the Gelidiales and is likely to be valuable for the inference
of phylogenetic relationship among other red algal taxa.
