Novel Sarcoscypha Species from National Parks in Korea: Sarcoscypha humida sp. nov.

ABSTRACT: Sarcoscypha (Sarcoscyphaceae, Pezizales) is a saprobic fungus characterized by the cup or disc-shaped blight red apothecium and oblong to ellipsoid ascospores. The 18 species of Sarcoscypha were known to occur in Europe, North America, and tropical Asia. However, up to date, only two Sarcoscypha species have been reported in Korea. In this study, novel Sarcoscypha specimens were collected from Juwangsan, Odaesan, and Taebaeksan National Parks from September to October in Korea. This species is well distinguished from other Sarcoscypha species according to the molecular and phylogenetic analysis based on internal transcribed spacer (ITS) region. Here, we provided detailed descriptions with illustrations and a phylogenetic tree to report our specimens as novel Sarcoscypha species.

Project description:BackgroundAcute Oak Decline (AOD) is a decline disease first reported on native oaks in the UK, but in recent years reports from further afield such as Europe and the Middle East, indicate that the distribution and host range is increasing at an alarming rate. The stem weeping symptoms of the disease partially develop due to polymicrobial-host interaction, caused by several members of the order Enterobacterales. While investigating the rhizosphere soil of AOD-unaffected trees, termed 'healthy' trees, and diseased oaks suffering from Acute Oak Decline (AOD), an enrichment method designed for enhanced recovery of Enterobacterales led to the recovery of several isolates that could not be classified as any existing species. These isolates showed a close relationship to the genus Leclercia, of which both species are of clinical importance, but the type species Leclercia adecarboxylata also displays plant growth-promoting properties in the rhizosphere.ResultsPartial sequencing of four housekeeping genes revealed similarity to the genus Leclercia with varying degrees of relatedness. As such a complete polyphasic approach was used to determine the true taxonomic position of these isolates. This involved whole genome sequencing, phylogenomic analysis, phylogenetic analysis of both the 16S rRNA and four housekeeping gene sequences, combined with phenotypic testing and fatty acid analysis. Both the phylogenomic and phylogenetic analyses separated the isolates into four clusters, two of which were contained in the Leclercia clade. The remaining two clusters formed a separate lineage far removed from any currently defined species. Further investigation into the role of the isolates as plant growth-promoting bacteria as well as plant pathogens was investigated computationally, revealing a number of plant growth-promoting traits as well as virulence genes related to motility, adhesion and immune modulation.ConclusionBased on the genotypic and phenotypic data presented here, these isolates could be differentiated from each other and their closest neighbours. As such we propose the description of Leclercia tamurae sp. nov. (type strain H6S3T = LMG 32609T = CCUG 76176T), Silvania gen. nov., Silvania hatchlandensis sp. nov. (type strain H19S6T = LMG 32608T = CCUG 76185T) and Silvania confinis sp. nov. (type strain H4N4T = LMG 32607T = CCUG 76175T). Due to their interesting protein annotations and alignments, these species warrant further investigation for their role in relation to plant health.
