Abstract
The genomes of Ceratocystis eucalypticola, Chrysoporthe cubensis, Chrysoporthe deuterocubensis, Davidsoniella virescens, Fusarium temperatum, Graphilbum fragrans, Penicillium nordicum and Thielaviopsis musarum are presented in this genome announcement. These seven genomes are from plant pathogens and otherwise economically important fungal species. The genome sizes range from 28 Mb in the case of T. musarum to 45 Mb for Fusarium temperatum. These genomes include the first reports of genomes for the genera Davidsoniella, Graphilbum and Thielaviopsis. The availability of these genome data will provide opportunities to resolve longstanding questions regarding the taxonomy of species in these genera. In addition these genome sequences through comparative studies with closely related organisms will increase our understanding of how these pathogens cause disease.
Highlights
Many species of Ceratocystidaceae have been studied extensively due to their signi cance as pathogens of agricultural forestry crops (Roux & Wing eld 2009), as well as their impact on natural woody ecosystems (Roux et al 2007, Lee et al 2015)
Isolates of Ceratocystis from Eucalyptus in South Africa, related to those known to kill trees in these plantations, were described as the new species C. eucalypticola. The taxonomy of this species and some of its relatives remains open to debate (Fourie et al 2015, Oliveira et al 2015) and there is a clear need to gain a deeper understanding of species boundaries as well as issues relating to its biology and ecology
The assembly was submitted to AUGUSTUS (Stanke et al 2004) in order to predict putative open reading frames (ORFs) using the gene models of Fusarium graminearum
Summary
Many species of Ceratocystidaceae have been studied extensively due to their signi cance as pathogens of agricultural forestry crops (Roux & Wing eld 2009), as well as their impact on natural woody ecosystems (Roux et al 2007, Lee et al 2015). Isolates of Ceratocystis from Eucalyptus in South Africa, related to those known to kill trees in these plantations, were described as the new species C. eucalypticola (van Wyk et al 2012) The taxonomy of this species and some of its relatives remains open to debate (Fourie et al 2015, Oliveira et al 2015) and there is a clear need to gain a deeper understanding of species boundaries as well as issues relating to its biology and ecology. The aim of this study was to sequence the genome of C. eucalypticola in order to allow for genomic analysis and comparisons with already available genomes from other Ceratocystidaceae (Wilken et al 2013, van der Nest et al 2014a, b) These comparisons, coupled with phylogenomic studies, will be useful in resolving the taxonomic debates ongoing in Ceratocystis.
