    Biology of Fungi, Lecture 2: The Diversity of Fungi and Fungus-Like Organisms Terms You Should Understand u ‘Fungus’ (pl., fungi) is a taxonomic term and does not refer to morphology u ‘Mold’ is a morphological term referring to a filamentous (multicellular) condition u ‘Mildew’ is a term that refers to a particular type of mold u ‘Yeast’ is a morphological term referring to a unicellular condition Special Lecture Notes on Fungal Taxonomy u Fungal taxonomy is constantly in flux u Not one taxonomic scheme will be agreed upon by all mycologists u Classical fungal taxonomy was based primarily upon morphological features u Contemporary fungal taxonomy is based upon phylogenetic relationships Fungi in a Broad Sense u Mycologists have traditionally studied a diverse number of organisms, many not true fungi, but fungal-like in their appearance, physiology, or life style u At one point, these fungal-like microbes included the Actinomycetes, due to their filamentous growth patterns, but today are known as Gram-positive bacteria u The types of organisms mycologists have traditionally studied are now divided based upon phylogenetic relationships u These relationships are: Q Kingdom Fungi - true fungi Q Kingdom Straminipila - “water molds” Q Kingdom Mycetozoa - “slime molds” u Kingdom Fungi (Mycota) Q Phylum: Chytridiomycota Q Phylum: Zygomycota Q Phylum: Glomeromycota Q Phylum: Ascomycota Q Phylum: Basidiomycota Q Form-Phylum: Deuteromycota (Fungi Imperfecti) Page 1 of 16 Biology of Fungi Lecture 2: Diversity of Fungi u Kingdom Straminiplia (Chromista)

  • Phakopsora Cherimoliae (Lagerh.) Cummins 1941
    -- CALIFORNIA D EPAUMENT OF cdfa FOOD & AGRICULTURE ~ California Pest Rating Proposal for Phakopsora cherimoliae (Lagerh.) Cummins 1941 Annona rust Domain: Eukaryota, Kingdom: Fungi Division: Basidiomycota, Class: Pucciniomycetes Order: Pucciniales, Family: Phakopsoraceae Current Pest Rating: Q Proposed Pest Rating: A Comment Period: 12/07/2020 through 01/21/2021 Initiating Event: In September 2019, San Diego County agricultural inspectors collected leaves from a sugar apple tree (Annona squamosa) shipping from a commercial nursery in Fort Myers, Florida to a resident of Oceanside. CDFA plant pathologist Cheryl Blomquist identified in pustules on the leaves a rust pathogen, Phakopsora cherimoliae, which is not known to occur in California. She gave it a temporary Q-rating. In October 2020, Napa County agricultural inspectors sampled an incoming shipment of Annona sp. from Pearland, Texas, that was shipped to a resident of American Canyon. This sample was also identified by C. Blomquist as P. cherimoliae. The status of this pathogen and the threat to California are reviewed herein, and a permanent rating is proposed. History & Status: Background: The Phakopsoraceae are a family of rust fungi in the order Pucciniales. The genus Phakopsora comprises approximately 110 species occurring on more than 30 dicotyledonous plant families worldwide, mainly in the tropics (Kirk et al., 2008). This genus holds some very important and damaging pathogen species including Phakopsora pachyrhizi on soybeans, P. euvitis on grapevine, and P. gossypii on cotton. Phakopsora cherimoliae occurs from the southern USA (Florida, Texas) in the north to northern Argentina in the south (Beenken, 2014). -- CALIFORNIA D EPAUMENT OF cdfa FOOD & AGRICULTURE ~ Annona is a genus of approximately 140 species of tropical trees and shrubs, with the majority of species native to the Americas, with less than 10 native to Africa.

  • Plant Pathology Self Study Oct2011 REV.Pdf
    EXECUTIVE SUMMARY The Department of Plant Pathology is one of nine academic units in the College of Food, Agricultural, and Environmental Sciences (CFAES) at The Ohio State University, and is the sole academic unit dedicated to plant-microbe interactions in Ohio's Higher Education system. The department consists of faculty, students, post-docs, and staff located on the Columbus and Wooster campuses of OSU. Funding comes from the Ohio Agricultural Research and Development Center (OARDC) and Ohio State University Extension (OSUE) line items, and from OSU Academic Programs; higher levels of financial support are obtained from external grants, contracts and gifts. Research programs in the department encompass basic investigations of plant-microbe interactions at the molecular level to studies of epidemics at the population level, and, in parallel, mission-oriented investigations of management tactics for diseases of major crops and forest trees. Graduate education is one of the foundations of the department. Currently, there are about 2.5 graduate students per faculty advisor; 217 students have enrolled in our graduate program over the last two decades, and many of our graduates have gone on to leadership roles in academia, government and private industry. The department is fully committed to undergraduate education, with a major in Plant Health Management, a minor in Plant Pathology, a new Plant Pathology major, and courses designed for non-majors. Although our UG enrollment in our major is small, our students are very successful, and 70% ultimately enroll in graduate school. Through the use of oral, printed, and electronic media, we are at the forefront in the college in outreach and engagement efforts, primarily through our Extension education programming.
