摘要

本研究调查了南安达曼岛Sri Vijaya Puram海岸红树林根系相关内生真菌的多样性。2014年7月至2016年7月，在五个站点采集了根样。从637个根段共分离到256株真菌，其中尖根（Rhizophora apiculata）高跷根的多样性最高，H′= 2.276。利用形态学特征和基于ITS区域的分子方法进行真菌鉴定，并使用BLAST将序列与NCBI GenBank数据库中的条目进行比较，结果显示大多数分离株属于子囊菌门。详细的研究结果强调了与红树林根系相关的真菌群的生态意义，表明它们在南安达曼沿海水域的营养循环和生态系统稳定中具有潜在作用。

Distribution and DNA Barcodes of Endophytic Fungi From Mangrove Roots of South Andaman Island

This study investigates the diversity of endophytic fungi associated with mangrove roots along the Sri Vijaya Puram coast, South Andaman. Root samples were collected from five stations between July 2014 and July 2016. A total of 256 fungal isolates were obtained from 637 root segments, with the highest diversity (H′ = 2.276) recorded in the stilt roots of Rhizophora apiculata . Fungal identification was performed using morphological characteristics and ITS region-based molecular methods, with sequences compared to entries in the NCBI GenBank database using BLAST, revealing that most isolates belonged to the phylum Ascomycota. The detailed findings emphasize the ecological significance of mycobiota associated with mangrove roots, suggesting their potential role in nutrient cycling and contribution to ecosystem stability in the coastal waters of South Andaman.

期刊介绍： Marine Ecology publishes original contributions on the structure and dynamics of marine benthic and pelagic ecosystems, communities and populations, and on the critical links between ecology and the evolution of marine organisms. The journal prioritizes contributions elucidating fundamental aspects of species interaction and adaptation to the environment through integration of information from various organizational levels (molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, palaeontology and modelling) as viewed from an ecological perspective. The journal also focuses on population genetic processes, evolution of life histories, morphological traits and behaviour, historical ecology and biogeography, macro-ecology and seascape ecology, palaeo-ecological reconstruction, and ecological changes due to introduction of new biota, human pressure or environmental change. Most applied marine science, including fisheries biology, aquaculture, natural-products chemistry, toxicology, and local pollution studies lie outside the scope of the journal. Papers should address ecological questions that would be of interest to a worldwide readership of ecologists; papers of mostly local interest, including descriptions of flora and fauna, taxonomic descriptions, and range extensions will not be considered.
