Cochliobolus: an overview and current status of species

The genus Cochliobolus (anamorphs Bipolaris, Curvularia) comprises many destructive plant pathogens that cause severe crop losses worldwide. The taxonomy of Cochliobolus is confused as frequent nomenclatural changes have occurred in the sexual and asexual states of species over the past 50 years. We provide an overview of these nomenclatural changes together with a morphological circumscription of the genus. Taxonomic notes and information about the life history of 55 species epithets of Cochliobolus listed in Index Fungorum are also given. Further information is given concerning the location of type cultures; availability of DNA sequence data derived from type cultures; mode of life; novel metabolite production; and use of Cochliobolus species in biocontrol. We provide a multilocus phylogenetic tree based on DNA sequence data derived from 25 ex-type and authentic cultures that shows the group as monophyletic. This paper represents the first comprehensive overview of Cochliobolus since 1987, including a summary of applications of species and molecular phylogenetic research. The 55 species of Cochliobolus are listed alphabetically, with synonyms, hosts and diseases, brief notes concerning taxonomic and phylogenetic research.

Measuring and monitoring biodiversity in tropical and temperate forests: proceedings of a IUFRO symposium held at Chiang Mai, Thailand August 27th-September 2nd 1994

PrefaceThis book contains 24 papers selected from among those presented at an international symposium on Measuring and Monitoring Biodivcrsity in Tropical and Temperate Forests , held in Chiang Mai, Thailand, between the 27th of August and 2nd of September, 1994. The symposium was attended by over 240 scientists from more than 40 countries from around the world. In addition to four days of paper presentations, there was also a one-day field trip, and a continuous poster session, with more than 35 posters, as well as computer demonstrations of software packages for identifying and measuring biodiversity.Biodiversity is an immense subject, and as tropical and temperate forests are home to a large proportion of the earth s terrestrial biodiversity, it is obviously very difficult to cover the topic comprehensively in a single volume. The papers included in this book were selected to give as broad a coverage as possible of key topics under the general title, including Principles of Measuring and Monitoring Biodiversity (8 papers), Genetic Diversity (6 papers), Species and Ecosystem Diversity (5 papers), and Methodology (5 papers). Inevitably, forest trees are the theme of many papers, but also included are papers dealing with diversity of arthropods, microfungi, birds and butterflies, and gibbons, as well as many papers dealing with the entire range of biodiversity.We would like to thank many people who helped to make the symposium and this book possible. Among these are the sponsors of the symposium, the Royal Forest Department of Thailand, the Commission of the European Communities, the Canadian International Development Agency (including the ASEAN Forest Tree Seed Centre and SADCC Tree Seed Centre Network), the Canadian Forest Service, the U.S. Forest Service, the Center for International Forestry Research, and the International Plant Genetic Resources Institute.We would also like to acknowledge the contribution of the entire Organizing Committee in Thailand, and particularly the assistance of Ms. Rosita Go of CIFOR, for her work before, during, and after the symposium, especially in arranging financial support for developing country scientists, and preparing the manuscripts for publication. Professor Tern had been working on wild flowers and wild plants from the very beginning of his career until the end of his life. He acquired an enormous depth of experience in botany, on his own, by trekking through all the forests and regions of Thailand. His worldwide reputation meant that any visiting botanist or forest scientist were always recommended to see him when they visited Thailand.At the end of his life, he contributed actively to the debate on forest biodiversity. He was a member of the organizing committee for the IUFRO Symposium on Measuring and Monitoring Biodiversity in Tropical and Temperate Forests , held in Chiang Mai, August 27 -September 2, 1994. He presented the keynote speech at the Symposium, which is included in these Proceedings, and led participants on a field trip to examine forest biodiversity at...

“…Usually surveys would be carried out, disease material collected, dried and returned to the laboratory where the associated fungi were later identified (Hyde & Alcorn, 1993). Molecular data have rapidly advanced the understanding of species boundaries and relationships in several important plant pathogenic genera, revealing numerous cryptic species (Cai et al, 2009;Kvas et al, 2009;.…”

OUTLINEPlant pathogenic fungi have long been documented through concerted efforts of mycologists and plant pathologists; these records have served as the basis for regional and countrywide checklists which have since been put into databases listing hosts and associated fungi. They are used by governments and scientists to formulate trade quarantine policies and determine research funding, such as in plant breeding programs and disease control. With the ability to use molecular characters to study the systematics of fungi it is clear that morphologically defined species are often large complexes comprised of genetically and biologically distinct species. Use of molecular techniques to examine species complexes has revealed cryptic species in many important plant pathogenic genera, e.g. Botryosphaeria, Colletotrichum, Fusarium, and Mycosphaerella. It has occurred to such an extent that existing checklists and databases need updating. It is important that the data from these studies, including changes in taxonomy and nomenclature, be incorporated into the databases of plant pathogenic fungi to support accurate plant quarantine decisions. In addition, epitypifying fungi by re-collecting material from type habitats and isolating the organism into pure culture will provide essential materials for systematics studies to further clarify the taxonomy and phylogeny of plant pathogenic fungi. Overall, we conclude that disease lists are likely to be highly outdated and advocate the need for countrywide re-inventory of plant pathogens. As a result of these studies, tools can be developed that use morphological or molecular characters, or both, to promote accurate identification of plant pathogenic fungi.
