The eukaryotic cell emerged as an evolutionary algorithmic phase transition / Eukaryogenesis happened abruptly, led by the tension of increasing gene length and the constraints on producing longer proteins / Evolvement of the eukaryotic cell is the most significant increase in complexity in the history of life's evolution on Earth 👉 https://press.uni-mainz.de/eukaryotic-cell-emerged-as-evolutionary-algorithmic-phase-transition/

Princeton University and Xiamen University researchers report that in tropical and subtropical oligotrophic waters, ocean acidification reduces primary production, the process of photosynthesis in phytoplankton, where they take in carbon dioxide (CO2), sunlight, and nutrients to produce organic matter (food and energy).
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.

Prokaryotic single-celled organisms, the ancestors of modern-day #bacteria and #archaea, are the most ancient form of #life on our #planet, first appearing roughly 3.5 billion years ago.
The first #eukaryotic cells appeared around 1–1.5 billion years later.
However, eukaryotic cells have since diversified into many complex, #multicellular organisms that we see around us every day—#fungi, #plants and #animals—while prokaryotes have remained decidedly unicellular.

"We identified two anti-CRISPR proteins AcrIC8 and AcrIC9 that strongly inhibit Neisseria lactamica I-C function. Structural analysis showed that AcrIC8 inhibits PAM recognition through allosteric inhibition, whereas AcrIC9 achieves so through direct competition. Both Acrs potently inhibit I-C-mediated genome editing and transcriptional modulation in human cells, providing the first off-switches for type I #CRISPR #eukaryotic #genome #engineering."

Beautiful and extremely useful #open #resource from Yana Eglit and @pjkeelinglab depicting eukaryotic microbes in exquisite detail.
Aren’t they lovely? Which is your favorite?

The microbial world is diverse and critically important to understanding evolution and global ecology, but we lack teaching and communications resources. This Essay provides a series of technical diagrams to aid with teaching and communication on the complexity and diversity of microbial eukaryotes.
