The considerable diversity of the basidium-like cells (IMAGE)
Caption
Figure 3 This figure illustrates the considerable diversity of the basidium-like cells. They occur in a range of shapes and developmental stages and are often associated with clamp connections. In some cases, they produce lateral cells, while others contain multiple nuclei or appear to be connected to neighbouring hyphae. The researchers also observed yeast-like cells budding from the hyphae, suggesting that the fungus may be capable of switching between different modes of growth. Together, the images provide insight into the formation and development of these distinctive cellular structures.

Figure 3. Variation in the morphology of the basidium-like cells (BLC) in Semicentenialea rex sp. nov. G–L 3D volume renderings of z-stacks, nuclei stained with propidium iodine (magenta) and cell walls and septa with calcofluor white (cyan). A–F BLCs with basal clamp connections (arrows). C A lateral cell arising from the BLC stalk (arrowhead). G BLCs with lateral cells with one nucleus (arrows), one BLC with a ring of strong calcofluor white staining in the obovoid cell and one nucleus in each department. Clamp connection forming (arrowhead), and yeast cells budding from hyphae indicated with strong calcofluor white staining at the base (asterisk). H BLC formed from a thick-walled probasidial-like swelling (TLC) (arrowhead), forming a second BLC with two nuclei in the obovoid cell and one in the lateral cell (arrow). Rotating 3D rendering of H as Suppl. material 4: movie S3. I Two globose BLCs in a string. J Lateral cell of a BLC anastomosing to the generative hypha (arrow), three nuclei in the obovoid cell. K BLC with a basal clamp connection (arrow). L Possible early stage of a BLC with four nuclei. Isolate HU4107 (A, C–F); JH144 (B), HU4064, type (G–L). Scale bars 10 μm (A–G); 4 μm (H–I, K); 5 μm (J); 3 μm (L).
