Ultrastructural observations of vegetative cells of two new genera in the Erythropeltidales (Compsopogonophyceae, Rhodophyta): Pseudoerythrocladia and Madagascaria

摘要: Two new genera of red algae, Madagascaria erythrocladioides West et Zuccarello and Pseudoerythrocladia kornmannii Kikuchi (Erythropeltidales, Compsopogonophyceae, Rhodophyta), were previously described using molecular analysis confocal microscopy isolates in laboratory culture. We examined the ultrastructure both to compare with other members class Compsopogonophyceae. Both had Golgi bodies not associated mitochondria chloroplasts a peripheral encircling thylakoid similar all studied thus far. Confocal autofluorescence images showed that has single round central pyrenoid while no pyrenoid. Our electron microscopic work confirms these initial observations.
