Coordination of Morphogenetic Activity in Modern and Fossil Communities of Cyanobacteria

摘要

Abstract— The phenomenon of morphogenesis was previously studied primarily in eukaryotes, in which it acquired developed and stable forms. For this reason, the emergence and formation of morphogenesis in eukaryotes is an area of reconstruction. Communities of filamentous cyanobacteria allow us to directly observe the initial stages of morphogenesis. At a high rate of morphogenetic processes, modern cyanobacterial communities form a specialized system to manage morphogenesis, a polygonal network. The coordinated behavior of cyanobacterial filaments is provided by complex electrical communication. The microrelief of the surface described earlier in stromatolites may be a manifestation of a similar system.
