The first plastid genome of a filamentous taxon ‘Bangia’ sp. OUCPT-01 in the Bangiales

Abstract Red algae are important primary photosynthetic organisms. The Bangiales comprise a morphologically diverse order of red algae. Until now, complete plastid genomes of the Bangiales were only mapped for foliose species. To date, no filamentous plastomes have been published. The aim of this st...
