Cryptophyta
WebSurprisingly, Cryptophyta were the most abundant bacterivores, although this phylum has been so far assumed to be mainly autotrophic. Moreover, the growth of a small lineage of Cryptophyta (CRY1 clade) was strongly stimulated by one Limnohabitans strain in our experiment. Thus, our study is the first report that colorless Cryptophyta are major ... WebThey have one or two plastids containing chlorophyll a and c, diadinoxanthins and fucoxanthins. The plastid is surrounded by four membranes, the outermost corresponding to the membrane of the reticulum as in Cryptophyta. On the other hand, if there is any integrated Rhodophyta reticulum, its nucleus has completely disappeared, unlike in ...
