Large groups of unicellular eukaryotes, non-bacterial unicellular organisms - microalgae,
Most eukaryotes need to survivemicrobiome. While we know how large eukaryotes - humans, corals, and plants - control their microbiome, scientists don't know how single-celled eukaryotes, such as microalgae, do it.
In humans, the microbiome can affect digestion,physical characteristics, weight, susceptibility to disease and even mental health. In corals, the microbiome supports the reefs and enables them to resist environmental changes. In trees, it provides essential nutrients. In microalgae - supports their life.
Researchers from NYUAD and other institutionsdiscovered that single-celled eukaryotes can control the behavior and growth of microbiomes by promoting beneficial microbes and preventing harmful (parasitic) microbes from approaching.
The findings allow scientists to predicthow climate change will affect fisheries and atmospheric gas composition. The point is that single-celled eukaryotes in the oceans are responsible for a huge part of the production of oxygen on Earth. In addition, they support the marine food web, including fish and coral reefs. The data obtained during the study will also expand scientists' understanding of evolution, because it is unicellular eukaryotes that make up a significant part of life on Earth.
"The discovery that the chemical sequenceallows some unicellular eukaryotes to manipulate the behavior of bacteria is of great importance, since most of the existing on Earth are unicellular, and many of them are necessary for our survival, "the author of the study concludes.
