Chloropicaceae
Chloropicophyceae is a class of green algae in the division Chlorophyta that, along with Picocystophyceae, coincides with the traditional "prasinophyte clade VII".Members of this class are coccoid green cells, with a diameter of 1.5–4 μm, found in marine waters, with one nucleus, one mitochondrion, and one chloroplast surrounded by two membranes, containing starch grain; their single chloroplast has chlorophylls a and b; they lack pyrenoid and flagella; and they have a layered cell wall.[1] In total, this class contains eight newly described species, belonging to two genera.The taxonomy goes as follows:[1] In the 2017 article where the new class is described, it is shown as the sister clade of the class Picocystophyceae.The internal relationships are shown in the tree below, which is a simplified version of the phylogenetic tree elaborated in the research:[1] Chlorokybus atmophyticus (outgroup) core Chlorophytes Picocystis salinarum Chloroparvula pacifica Chloroparvula japonica Chloropicon maureeniae Chloropicon mariensis Chloropicon laureae Chloropicon primus Chloropicon sieburthii Chloropicon roscoffensis This article incorporates "Chloropicophyceae, a new class of picophytoplanktonic prasinophytes" text from this source, which is by Adriana Lopes dos Santos, Thibaut Pollina, Priscilla Gourvil, Erwan Corre, Dominique Marie, José Luis Garrido, Francisco Rodríguez, Mary-Hélène Noël, Daniel Vaulot and Wenche Eikrem available under the CC BY 4.0 license.
