Polytomella is a genus of green algae, specifically of the Chlamydomonadaceae.[1] Polytomella is a free-living, flagellated, nonphotosynthetic green alga with a highly reduced, linear fragmented mitochondrial genome.[2][3] Polytomella, as it exists today, bears evidence of once having a functional photosynthetic plastid which has over evolutionary time changed such that it would appear now to have no genome or gene expressing mechanisms remaining to it.[4] Having transitioned completely to heterotrophy, Polytomella uses organic acids, alcohols and monosaccharides as its carbon source.[3][5][6] Despite being an evolutionary descendent of the green algae, Polytomella is a colourless organism because it has lost its photosynthetic ability.[6]
