Prototaxites represents the first giant organisms to live on the terrestrial surface, reaching sizes of 8 metres in the Early Devonian.
It was an extinct lineage of #multicellular terrestrial #eukaryotes.
Assignments to groups of multicellular algae or land plants have been repeatedly ruled out leaving two major alternatives: #Prototaxites was either a #fungus or a now entirely extinct lineage.
The latter hypothesis seems more plausible based on nrw evidence.

How do #phages impact #Streptomyces physiology? @BuryMone &co show that induction of the #prophage 'Samy' enhances dispersal of #multicellular aggregates of S. ambofaciens #bacteria in response to stress, likely promoting lineage propagation #PLOSBiology https://plos.io/3LDRNib

New research shows the complexity of #bacterial circadian clocks
https://phys.org/news/2023-08-complexity-bacterial-circadian-clocks.htmlThe #CircadianClock of the #bacterium B. subtilis evokes properties of complex, #multicellular circadian systems https://www.science.org/doi/10.1126/sciadv.adh1308 by Francesca Sartor et al.
"The circadian clock in this #microbe is pervasive: we see it regulating several #genes, and a range of different behaviors."

#FossilAdventCalendar Day 4
The oddest and - at over 560 million years in age - oldest #fossil featured in this #AdventCalendar is Fractofusus misrai from #Newfoundland 🇨🇦. This specimen in the #RoyalOntarioMuseum is from #MistakenPoint, one of the sites preserving the #Ediacaran #biota, the term for some of our planet's oldest #multicellular #fossils. Lots of questions remain about these ancient enigmas, among them, were #Ediacarans #animals or members of a different branch of the tree of life?

#Yellow #pigment keeps #SocialAmoebae together https://www.eurekalert.org/news-releases/968378 #Protists #SlimeMolds #Polyketides #Pigments
Paper: Yellow #polyketide pigment suppresses premature #hatching in social amoeba https://www.pnas.org/doi/10.1073/pnas.2116122119
The #multicellular stage of the #amoeba #Dicyostelium discoideum is partially regulated by an intensely yellow natural substance. The newly identified natural product of the polyketide family prevents the #amoebae #spores from hatching too early.
