Genetic diversity of Gracilaria changii (Gracilariaceae, Rhodophyta) from west coast, Peninsular Malaysia based on mitochondrial cox1 gene analysis

Mitochondrial cytochrome c oxidase subunit I (cox1) was employed to investigate the intraspecific genetic diversity of Gracilaria changii collected from various localities distributed along the west coast of Peninsular Malaysia. Gracilaria changii is an agarophyte with potential for commercializatio...
