The organism also has characteristics usually associated with protists and amoebas, two different branches. This left researchers wondering where the microorganism fits into the tree of life.

Endosymbiosis between protists and bacteria represents a fundamental biological phenomenon that has shaped the course of eukaryotic evolution. These intimate associations, in which one organism ...

There are three domains of life: bacteria, archaea, and eukarya. Eukaryotic cells are more complex than bacteria, but there are single-celled eukaryotes, and those that don't fit into any other ...

Among the large cast of microbiome players, bacteria have been hogging the spotlight. But the single-celled organisms known as protists are finally getting the starring role they deserve.

Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria, which generate chemical energy using oxygen. However, a new study by Lukáš Novák and ...

Most were from viruses known to infect bacteria - presumably representing parasites of the protists' bacterial prey. But choanozoans and picozoans, which only occurred in the Gulf of Maine sample ...

Scientists scooped up the organisms, known as protists, from the surface waters of the Gulf of Maine and the Mediterranean Sea off the coast of Catalonia, Spain.They found a slew of viral DNA ...

Their natural hosts are single-celled organisms with a cell nucleus, the protists. When giant viruses infect a host cell, they remodel the entire host cell and set up a so-called "virus factory." ...

The organism also has unique characteristics usually associated with protists and amoebas, two different branches. This left researchers wondering where the microorganism fits into the tree of life.

Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria -- the 'powerhouses of the cell,' which generate chemical energy using oxygen. However, a new ...
