This study is the first time-lapse report on the dynamic movements of sexual and asexual reproductive processes by live imaging in <i>Gilbertella persicaria</i> (<i>Choanephoraceae, Mucorales</i>). Our live imaging analysis indicated the formation of zygospores begin immediately after two aerial hyphae contact whether at the tip or middle of the hyphae.

When a zygospore was formed near the tip of hypha in contact with the partner hypha, the hyphal growth ceased. When zygospore was formed behind the tip of the hypha, the hyphal growth continued without slowing down.

Nevertheless, the biosynthetic pathway behind this phenomenon was only very recently resolved. Fungal bioluminescence occurs in five distantly related linages (<i>Omphalotaceae</i> lineage, <i>Armillaria</i> lineage, mycenoid lineage, Lucentipes lineage and <i>Eoscyphella</i> lineage) of the basidiomycete order <i>Agaricales</i>. Recent research suggests fungal bioluminescence has emerged 160 million years ago in the most common ancestor of the mycenoid and marasmioid clade and is maintained since then. Surprisingly, in the mycenoid linage, primarily represented by the genus <i>Mycena</i>, most species are considered non-luminescent, implying that many mycenoid species have lost their bioluminescent ability. Here, we report evidence for bioluminescence in <i>Mycena crocata</i> and show that the genome of this species is fully equipped with the genes associated with fungal bioluminescence. <i>Mycena crocata</i> is a long-known species frequently reported from Europe and Japan, which was considered non-luminescent until now. The low light emission intensity and the restriction of the luminescence to the vegetative mycelium and the base of the basidiome may be reasons why bioluminescence was not perceived earlier. We assume there might be other known <i>Mycena</i> species whose luminescent properties are not yet discovered, and that therefore the number of bioluminescent <i>Mycena</i> species is currently underestimated. </p>\u0000<p></p>","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140927241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sexual reproduction, which is common, leads to high lichen genetic diversity and low photobiont selectivity. However, the lichen genus <i>Endocarpon</i> adopts a special co-dispersal model in which algal cells from the photobiont and ascospores from the mycobiont are released together into the environment. To explore the dispersal strategy impact on population structures, a total of 62 <i>Endocarpon</i> individuals and 12 related Verrucariaceae genera individuals, representing co-dispersal strategy and conventional independent dispersal mode were studied. Phylogenetic analysis revealed that <i>Endocarpon</i>, with a large-scale geographical distribution, showed an extremely high specificity of symbiotic associations with their photobiont.

This study suggested that the ascospore-alga co-dispersal mode of <i>Endocarpon</i> resulted in this unusual mycobiont-photobiont relationship; also provided an evidence for the horizontal transfer of group I intron that may suggest the origin of the complexity and diversity of lichen symbiotic associations.</p>\u0000<p></p>","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140827142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
