Abstract

Abstract - Marine macroalgae are a polyphyletic group of photosynthetic eukaryotes and play critical roles in oxygen production, as primary producers, and in providing physical habitat structure. They harbor diverse microbial communities, including mutualistic, commensalistic, and parasitic fungi. These fungi may be obligately or facultatively marine and symbiotic. In this investigation, we isolated endophytic algicolous fungi from marine macroalgae collected from 5 intertidal sites in Nova Scotia. Fungi were cultured from surface-sterilized algal tissue and identified using ITS rDNA barcoding. From 21 marine macroalgal species collected, 11 algal species harbored endophytic fungi. We identified 23 endophytic algicolous fungi from the Bay of Fundy and Atlantic coasts of Nova Scotia. Marine endophytes are a promising new resource for bioactive compounds.

新斯科舍省海洋大型藻类的内生真菌

摘要-海洋巨藻是一种多系的光合真核生物，作为初级生产者，在氧气生产和提供物理栖息地结构方面发挥着关键作用。它们孕育着不同的微生物群落，包括共生的、共生的和寄生的真菌。这些真菌可能是专性或兼性的海洋和共生的。在这项调查中，我们从新斯科舍省5个潮间带地点采集的海洋大型藻类中分离出内生藻真菌。从表面灭菌的藻类组织中培养真菌，并使用ITS rDNA条形码进行鉴定。在采集到的21种海洋大藻中，有11种藻类携带内生真菌。我们从新斯科舍省芬迪湾和大西洋沿岸鉴定了23种内生藻真菌。海洋内生菌是一种很有前景的生物活性化合物新资源。

期刊介绍： The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion. The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
