Deposition Authors: Zhao LS , Li K , Zhang YZ , Liu LN. Structural basis and evolution of the photosystem I-light-harvesting supercomplex of cryptophyte algae. Zhao LS , Wang P, Li K , Zhang QB, He FY ... Cryptophytes are distinguished by the presence of characteristic extrusomes called ejectosomes or ejectisomes, which consist of two connected spiral ribbons held under tension. If the cells are irritated either by mechanical, chemical or light stress, they discharge, propelling the cell in a zig-zag course away from the disturbance. Large ejectosomes, visible under the light microsc…

Comparative mitochondrial genomics of cryptophyte algae: gene …

WebCryptophyte algae are globally distributed photosynthetic flagellates found in freshwater, estuarine, and neritic ecosystems. While cryptophytes can be highly abundant and are consumed by a wide variety of protistan predators, few studies have sought to quantify in situ grazing rates on their populations. Here we show that autumnal grazing rates on in … WebThese were found in alveolate, cryptophyte, haptophyte and rhizarian phytoplankton as well as taxa from two lineages previously known to … biological secondary treatment
