Progress 05/01/08 to 09/30/12
Outputs
OUTPUTS: Training was provided for 12 undergraduate students, six graduate students, two post-doctoral fellows, three visiting scientists/interns, and two research associates. Additional student (undergraduate and graduate) training and access to equipment was provided for those engaged in research projects within the LSU AgCenter. This project provided laboratory material and lecture data for academic courses for students in five departments (Renewable Natural Resources, Entomology, Biological Sciences, Horticulture, and Plant Pathology). Five invited presentations, numerous contributed presentations, and departmental seminars were generated from results of this project. Consulting activities include fungal identification for the Plant Disease Diagnostic Clinic at LSU, as well as scientists and citizens. Development of a database for recording rusts reported or collected in the state of Louisiana, including host data, geographic data, voucher details, and literature/herbarium citations was initiated. The addition of data and herbarium vouchers from nearly 100 new rust collections from Louisiana, and more than 100 collections of Phakopsora pachyrhizi (causal agent of soybean rust) were used to help determine the genetic diversity of this pathogen in Louisiana. Hundreds of sequences have been deposited into the public GenBank database. Numerous vouchered specimens have been placed into the LSU herbarium to be maintained in perpetuity and provide a permanent scientific resource. PARTICIPANTS: Mary Catherine Aime (PI), Ramandeep Kaur, Gregory Heller, Maj Padamsee, Merje Toome, Tomas Rush, Youwen Gong, Andrew Rodriguez, Sebastian Albu, Jorge Diaz, Donald Nelsen, and Nicole Ward, LSU AgCenter. One high school student Emily Salzer, was supported by this project and received general laboratory training. Training in general mycology including field collection, culturing, and molecular techniques was provided to numerous LSU undergraduate students including Jeanclaude Jubert, Bethany Kennedy, Bryan Goldberger, Paige Muse, Michelle Warr, Shiquita Brooks, Kelly Landry, Catherine Perino, Katie Stephenson, Aislinn Smith, Andrew Lloyd, Whitney Pilcher, and Alex Cassara. This project also supported training of one exchange student from the University of Tennessee, Jennifer Kozeman, and four summer interns, Clare Whittaker and Rohan Hebbar (University of Maryland) and Nattawut Boonyuen and Amnat Eamvijarn (Thailand). TARGET AUDIENCES: Target audiences for this project are other researchers and students in mycology, plant pathology, and systematics as well as plant breeders, diagnosticians, and the amateur mycological community. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Historical searches revealed 163 previously recorded species of rust in Louisiana, which is a 300% increase in the number of rust species in the state prior to the initiation of this project. In addition, knowledge of the world distribution and biology of rusts included, for example, development of a fungal barcoding locus, analysis of Melampsora species in the pacific northwest US, description of several mycoparasites of rusts, and description of an entirely new fungal class. New molecular protocols and techniques were developed exclusively for working with rust fungi and their relatives. Rust-specific primers were tested for effectiveness as rust barcodes. Twenty-five new single-copy protein genes were screened for their applicability at different phylogenetic levels; specific primers were created for three of these and three supplementary barcode candidate genes were identified and further tested, although ultimately all failed in one or more barcoding criteria. Specimen collecting, molecular data collection, and multiple-gene analyses contributed to the resolution and the family and ordinal-level placement of several previously misclassified or incertae sedis pathogens and related environmental yeasts isolated from Louisiana. Protocols developed in the laboratory are now used by graduate students and pathogen diagnosticians in this Department and researchers at other universities. The findings are intended to provide early and improved identification of the causal agents of fungal disease agents and aid in developing more effective control measures.

Progress 01/01/10 to 12/31/10
Outputs
OUTPUTS: This project has contributed to the support of several activities, including the training of five undergraduates engaged in independent research and ongoing surveys of rust-infected hosts throughout the state of Louisiana that are conducted by all members of the laboratory (in addition to undergraduates, four graduate students and three post doctoral researchers). Supported events include attendance at the Mycological Society of America annual meeting (co-author on four papers, including the winner for best student poster presentation), International Mycology Conference (invited seminar speaker), Global Food Security and Plant Biosecurity annual symposium (invited symposium speaker), in each case to give presentations on data generated by this project. Consulting activities include fungal identification for the Plant Disease Diagnostic Clinic at LSU, the Forensic Anthropology and Computer Enhancement Services Laboratory at LSU, and dozens of scientists and citizens in Louisiana, other U.S. states, and internationally (e.g., Nigeria, Guam, Ecuador, South Africa). Products include the development of a database for the recording of all rust fungi reported or collected in the state of Louisiana, including host data, geographic data, voucher details, and literature/herbarium citations has been created and all available historic (literature and herbarium) data have been collected and entered and the addition of data and herbarium vouchers from nearly 100 new rust collections from Louisiana, and more than 100 collections of Phakopsora pachyrhizi (causal agent of soybean rust) that will be used to determine the genetic diversity of this pathogen in Louisiana. PARTICIPANTS: Dr. Mary Catherine Aime, Assistant Professor (PI) provided project direction, data collection and analyses, database development and overall laboratory management and training. Dr. Ramandeep Kaur, Research Associate, and Dr. Gregory Heller, transient Research Associate, provided bench work (data collection) and laboratory maintenance and student training. Drs. Maj Padamsee and Merje Toome, Postdoctoral Associates, provided molecular protocol testing, molecular data collection and phylogenetic analyses. Mr. Tomas Rush, Youwen Gong, Andrew Rodriguez, and Sebastian Albu, graduate students, received training on microscopy, culturing, molecular biology, and field data collection and research guidance. Training and molecular and culturing laboratory facilities were supplied to several other graduate students within our department including Ms. Nicole Ward. Training in general mycology including field collection, culturing, and molecular techniques was provided to numerous LSU undergraduate students, Mr. Jeanclaude Jubert, Ms. Bethany Kennedy, Ms. Katie Stephenson, Ms. Aislinn Smith, Mr. Andrew Lloyd, and Mr. Alex Cassara, and two summer interns, Ms. Clare Whittaker (from University of Maryland) and Mr. Nattawut Boonyuen (from Thailand). TARGET AUDIENCES: Target audiences for this project are other researchers and students in mycology, plant pathology, and systematics as well as plant breeders, diagnosticians, and the amateur mycological community. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
Support of this project has contributed to significant changes in knowledge. Historical searches have revealed records of 163 previously recorded species of rust in Louisiana; this is a considerable increase over the 56 species currently accepted. Many additional species have thus far been collected and identified in Louisiana for which no prior record exists; three of these have been published. Additional publications contributing to knowledge of the world distribution and biology of rusts include, for example, elucidation of the life cycle of Puccinia acroptili, a survey of the rusts of Oman, new species of rusts from Turkey, a phylogeny of rusts on sugarcane, and new reports of rusts from South Africa and the Pacific Northwest. Several new molecular protocols and techniques have been developed exclusively for working with rust fungi and their relatives. Rust-specific primers have been developed and tested for the fungal barcode region (ITS); other loci have been tested for the international Barcode for Fungi effort. Twenty-five new single-copy protein genes have been screened for their applicability at different phylogenetic levels; specific primers have been created for three of these and three excellent candidate genes have been identified and further tested. Significant improvements to conducting large-scale DNA extractions and RNA extractions on Pucciniomycotina have been made. Specimen collecting, molecular data collection, and multiple-gene analyses have all contributed to the resolution and the family and ordinal level of several previously miss-classified or incertae sedis pathogens and related environmental yeasts isolated from Louisiana, resulting in a national meeting presentation and publication. Protocols developed in our laboratory have been requested and are now used by graduate students and pathogen diagnosticians in our department, researchers at other universities,for example Clark University, Massachusetts. The findings are intended to provide early and improved identification of the causal agents of fungal disease agents to aid in developing and providing more effective control measures.

Progress 05/01/08 to 12/31/08
Outputs
OUTPUTS: Support of this projected has generated four published abstracts for the 2008 Annual Meetings of the Mycological Society of America and the American Phytopathological Society. Results of the ongoing project were presented during 2008 by invitation to three professional meetings: The American Phytopathological Society Centennial Meeting, the NCERA 2008 Soybean Rust working group annual meeting, and the Taller de Ojo de Gallo Workshop hosted by CICAFE in San Jose, Costa Rica. Results were also shared with amateur mycologists at the Gulf States Mycological Society during an invited lecture at their annual summer foray, to colleagues at a departmental seminar given to the School of Renewable Natural Resources at LSU, and to graduate and undergraduate students via courses in Introductory Mycology and Forest Pathology taught by the PI. PARTICIPANTS: Dr. Mary Catherine Aime, Assistant Professor (PI)provided project direction and data analyses. Dr. Ramandeep Kaur, Research Associate (Sept-Dec 2008) provided bench work (data collection) and laboratory maintenance. Training in field collection and molecular laboratory techniques provided by PI to: Dr. Ramandeep Kaur, Research Associate; Amnat Eak (M.S. student and summer intern from Thailand, May-Aug 2008); Emily (high school student, May-Aug 2008); Jennifer Koseman (undergraduate exchange student from University of Tennessee, May 2008); Tomas Rush (undergraduate student, LSU, May-Dec 2008). TARGET AUDIENCES: Target audiences for this project are other researchers in mycology, phytopathology, and systematics as well as students and the amateur mycological community. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Sixty-nine collections of rust fungi and their relatives were made from Louisiana and neighboring areas on a variety of host plants, expanding the number of rusts known to occur in this state. Experiments to develop primers and protocols with better specificity for rust fungi resulted in a streamlined nested PCR technique and primers that successfully amplify rust from heterogeneous DNA extractions in 85% of cases. Primer testing is underway to screen 25 loci for applicability within Pucciniomycotina.
