Abstract

A total of 518 endophytic fungal taxa (excluding 105 taxa identified beyond the level of genus and Mycelia sterilia) from 370 genera belonging to 188 families (including forty six isolates of uncertain taxonomic positions), were isolated from seventeen different Cycads. The results revealed that, although members of Ascomycota were dominant, the presence of Basidiomycota, Mucoromycota, Chytridiomycota, Olpidiomycota and Zoopagomycota couldn't be ruled out.

The endophytic fungi associated with Cycadales have been reported to exist in different primary lifestyles viz. plant_pathogens (86 genera), wood_saprotroph (78 genera), litter_saprotroph (44 genera), soil_saprotroph (41 genera), animal_parasite (24 genera), unspecified_saprotroph (20 genera), mycoparasite (13 genera), nectar/tap_saprotroph (11 genera), na and lichenized (08 genera each), ectomycorrhizal (07 genera), dung_saprotroph (06 genera), foliar_endophyte and arbuscular_mycorrhizal (05 genera each), epiphyte (04 genera), algal_parasite (03 genera), pollen_saprotroph and root_endophyte (02 genera each), lichen_parasite, unspecified_pathotroph, sooty_mold (01 genera each) (excluding 105 taxa which were identified either up to class, order and family level or are treated as incertae sedis, and Mycelia sterilia) and possibly produce several toxic compounds.

In a nut shell, the presence of fungal endophytes of different life histories, in a Cycad's endobiome, their long evolutionary history of association with the leaf, and capability of producing several mycotoxins could possibly mediate herbivory, and these specific fungal endophytes could be identified as candidates for future functional study.

苏铁植物抵御昆虫和哺乳动物食草的能力：内生真菌有话要说吗？- 一个假设

从 17 种不同的苏铁植物中分离出了隶属于 188 个科 370 个属的 518 个内生真菌类群（不包括 105 个已鉴定为非属和菌丝体的类群）（包括 46 个分类位置不确定的分离物）。研究结果表明，虽然子囊菌科（Ascomycota）成员占主导地位，但也不排除基枝菌科（Basidiomycota）、黏菌科（Mucoromycota）、糜枝菌科（Chytridiomycota）、寡毛菌科（Opidiomycota）和祖枝菌科（Zoopagomycota）成员的存在。

期刊介绍： Fungal Biology Reviews is an international reviews journal, owned by the British Mycological Society. Its objective is to provide a forum for high quality review articles within fungal biology. It covers all fields of fungal biology, whether fundamental or applied, including fungal diversity, ecology, evolution, physiology and ecophysiology, biochemistry, genetics and molecular biology, cell biology, interactions (symbiosis, pathogenesis etc), environmental aspects, biotechnology and taxonomy. It considers aspects of all organisms historically or recently recognized as fungi, including lichen-fungi, microsporidia, oomycetes, slime moulds, stramenopiles, and yeasts.
