Tracing the evolutionary history of plant plastid and mitochondrial proteomes reveals that major changes in organelle biology may have facilitated plant diversification and the emergence of major plant lineages such as the land plants.

New #ISEPpapers! Multiple parallel origins of parasitic Marine Alveolates https://www.nature.com/articles/s41467-023-42807-0 #protists #parasites #microbes
"similar forms of #parasitism evolved multiple times and #photosynthesis was lost many times. By contrast, complete loss of the #plastid #organelle is infrequent and, when this does happen, leaves no residual #genes."
The Marine Alveolates (MALVs) include important parasites of other protists/animals. Here, using new data from MALV-I, the psammosids, and a new group called the eleftherids, the authors show MALVs, and therefore parasitism in early dinoflagellates, evolved from two distinct free-living ancestors.

In a recent article published in Nature Microbiology, we show how marine diatoms, a globally important group of microalgae can switch between photosynthesis and a light-driven rhodopsin proton pump to support growth in iron-deprived waters. (Poster image: Oliver Skibbe, CC BY 4.0)
