Endophytic fungi from Colobanthus quitensis leaves. (A) Colony-forming units (CFU) of culturable endophytic fungi per fresh plant weight unit (g) were evaluated for C. quitensis plantlets harvested in open areas (OA samples) as well as inside open-top chambers (OTC samples). Culturable fungi were grown at 25 ± 1 °C for 21 days on potato dextrose agar (PDA) supplemented with 0.25% lactic acid. No additional colonies could be observed for a longer incubation time. Mean Log₁₀ (CFU g⁻¹) and standard deviation values from three replicates (each as a pool of plants) are presented for each sample. (B) Relative abundances of taxa of culturable endophytic fungi assessed by morphological analyses. No significant differences were found among the collection sites (OA and OTC), according to Tukey’s test (p > 0.05).
