FIGURE 2 in Polyphasic characterization of Trichocoleus desertorum sp. nov. (Pseudanabaenales, Cyanobacteria) from desert soils and phylogenetic placement of the genus Trichocoleus

FIGURE 2. Morphological variability of various T. desertorum populations. A. Multiple trichomes in a common sheath (ATA3-4Q-KO9). B. Short trichome with short, strongly constricted cells (ATA1-4-KO5). C. Asymmetrical cell division (WJT40-NPBG1). D–E. Asymmetrical cell division and granules (arrows) in cells (CMT-1BRIN-NPC4B). F. Multiple trichomes in a colorless lamellated sheath with greyish light refraction (ATA14-3-RM36). G–H. Thylakoids in fascicles (arrows) (G. ATA14-3-RM36, H. ATA2-1-CV2). I–J. Involution cells (arrow) (I. WJT40-NPBG1, J. WJT55-NPBG8). K. Tapering trichome with pointed apical cell (ATA1-4-CV13). Scale = 10 µm.
