Journal ArticleDOI
Marine Fungi: Their Ecology and Molecular Diversity
TL;DR: Evidence for 36 novel marine lineages, the majority and most divergent of which branch with the chytrids, are discussed and what these data mean for the evolutionary history of the Fungi and specifically marine-terrestrial transitions are investigated.
Journal ArticleDOI
Horizontal gene transfer facilitated the evolution of plant parasitic mechanisms in the oomycetes
Thomas A. Richards,Thomas A. Richards,Darren M. Soanes,Meredith D. M. Jones,Meredith D. M. Jones,Olga Vasieva,Guy Leonard,Guy Leonard,Konrad Paszkiewicz,Peter G. Foster,Neil Hall,Nicholas J. Talbot +11 more
TL;DR: Using whole-genome, gene-by-gene phylogenetic analysis, an extensive pattern of cross-kingdom HGT between fungi and oomycetes is demonstrated, consistent with the hypothesis that some oomyCetes became successful plant parasites by multiple acquisitions of genes from fungi.
Journal ArticleDOI
A fungal pathogen secretes plant alkalinizing peptides to increase infection.
Sara Masachis,David Segorbe,David Turrà,Mercedes Leon-Ruiz,Ursula Fürst,Mennat El Ghalid,Guy Leonard,Manuel S. López-Berges,Thomas A. Richards,Georg Felix,Antonio Di Pietro +10 more
TL;DR: Fungal mutants lacking a functional Fusarium (F)-RALF peptide failed to induce host alkalinization and showed markedly reduced virulence in tomato plants, while eliciting a strong host immune response.
Journal ArticleDOI
Phylogenomic Analysis Demonstrates a Pattern of Rare and Ancient Horizontal Gene Transfer between Plants and Fungi
Thomas A. Richards,Darren M. Soanes,Peter G. Foster,Guy Leonard,Christopher R. Thornton,Nicholas J. Talbot +5 more
TL;DR: Comparing the genomes of six plant species with those of 159 prokaryotic and eukaryotic species and identifying 1689 genes that show the highest similarity to corresponding genes from fungi suggests that two fungi-to-plant transfers have added phenotypes important for life in a soil environment.
Journal ArticleDOI
Molecular diversity and distribution of marine fungi across 130 European environmental samples
Thomas A. Richards,Thomas A. Richards,Guy Leonard,Frédéric Mahé,Javier del Campo,Javier del Campo,Sarah Romac,Meredith D. M. Jones,Finlay Maguire,Finlay Maguire,Micah Dunthorn,Colomban de Vargas,Ramon Massana,Aurélie Chambouvet +13 more
TL;DR: A dual approach involving high-throughput diversity tag sequencing from both DNA and RNA templates and fluorescent cell counts is used to evaluate the diversity and relative abundance of fungi across marine samples taken from six European near-shore sites, demonstrating the phylogenetic position and environmental distribution of 71 lineages.
