| 英文摘要 | Using high-throughput sequencing and molecular analysis of the nuclear ribosomal DNA (rDNA) internal transcribed spacer (ITS) region, we investigated the diversity of algicolous fungi associated with the green macroalga Ulva pertusa. Agaricomycetes and Sordariomycetes were the most abundant classes, and most of these fungal taxa are saprotrophic, as revealed by metabarcoding data and analyzed using FunGuild. A total of 84 representative fungal isolates were obtained using traditional isolation methods, comprising 50 isolates of Ascomycota and 34 of Basidiomycota. In addition to documenting fungal diversity, we examined the growth response of selected isolates to two key cues: cyclic adenosine monophosphate (cAMP) and light. Several strains demonstrated enhanced growth under exogenous cAMP or light treatments, reflecting the physiological plasticity of these algicolous fungi. Confrontation assays further revealed that some isolates exhibit antagonistic activity against putative phytopathogenic fungi, suggesting a possible protective role for their host. Overall, this study provides the first comprehensive overview of fungal communities associated with U. pertusa and highlighted how external stimuli can shape their growth behaviors, offering valuable insights into the ecological functions of algicolous fungi in coastal ecosystems. |
