Abstract
Coniella has a wide distribution as a plant pathogen in Eucalyptus species. Here we report a leaf spot disease caused by Coniella eucalyptorum on Eucalyptus camaldulensis in Sri Lanka. The pathogen was isolated from symptomatic leaf samples of E. camaldulensis plants from Polonnaruwa District in Sri Lanka. The isolated fungus was identified as C. eucalyptorum based on morphological characteristics and multi-gene phylogenetic analysis of combined sequences of the internal transcribed spacer region (ITS), the partial translation elongation factor 1-α gene (tef1-α), and large subunit of nuclear ribosomal RNA (LSU). The pathogenicity test was performed to confirm its pathogenicity to the host, which produced symptoms similar to those observed in the field. This is the first report of C. eucalyptorum associated with Eucalyptus plantations in Sri Lanka. This finding is important to expand the knowledge of plant pathogen diversity in Eucalyptus species and other economically important crops in Sri Lanka.
期刊介绍：
Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis.
All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
