cellularinis

cellularinis is a genus of microscopic, unicellular organisms classified within the phylum Amoebopoda. First described in 2021 by Dr. L. Kim and colleagues, the type species is cellularinis globulus. Members of this genus are characterized by their spherical to ovoid bodies, ranging from 50 to 200 micrometres in diameter, and a simple, non-flagellated mode of motility driven by amoeboid pseudopod extensions. They lack a true nucleus, instead possessing a lobed chromatophilic region that houses genetic material in a dispersed chromatin matrix.

These organisms are predominantly found in freshwater and brackish environments, especially in the anaerobic sediments of temperate lakes. Recent field studies indicate that cellularinis species contribute significantly to the breakdown of organic matter in hypoxic zones, acting as primary consumers that recycle nitrogen and carbon. Their feeding habits involve phagocytosis of bacteria and detrital particles, a process regulated by a specialized cytoskeletal network composed of actin filament bundles.

The genome of cellularinis globulus has been sequenced, revealing a small, 6.5 megabase pair chromosome with 620 open reading frames. Comparative genomics suggests that cellularinis shares common ancestry with the class Ciliophora, yet it retains ancestral features such as the absence of kinetosomes. The genus was named to reflect its cellular engineering aptitude, as evidence shows that they can reorganize internal organelles when exposed to environmental stressors.

Ongoing research focuses on the biotechnological potential of cellularinis, particularly their capacity to produce extracellular enzymes that degrade complex polysaccharides. Studies also explore their role as model organisms for understanding cellular autophagy and programmed cell death, contributing to broader insights into eukaryotic life cycles.
