Molecular Evidence for the Wide Distribution of Two Lineages of Terrestrial Green Algae (Chlorophyta) over Tropics to Temperate Zone

Nonmetric multidimensional scaling (NMDS) diagram. The ordination based on Jukes-Cantor genetic distances among 9 environmental clones and 1 isolate representing a yet undescribed European species of the genus Xylochloris. For the analysis 18S partial sequences comprising hypervariable regions V2, V3, and V4 were used. The colors encode for three different habitats: green—tree bark, blue—forest soil, brown—grassland soil. For the corresponding accession numbers of the sequences see Table 1.
