Now that’s an interesting mushroom! In fact, fungi can be some of the most colorful species. And protists can be some of the most interesting. These two kingdoms which have some of the most diverse members are the first two eukaryotic kingdoms we discuss in the Protists and Fungi chapter. This quintessential toadstool, the fly agaric or fly Amanita, is a poisonous and psychoactive fungus. It has a large white-gilled, white-spotted, usually deep red mushroom, and it is one of the most recognizable and widely encountered in popular culture. You should not eat it. 2 www.ck12.org Chapter 1. Protists and Fungi 1.1 Protist Kingdom • Describe the protist kingdom. Prokaryote or eukaryote? This organism consists of a single cell with several flagella. Is it a prokaryote, such as a bacterium? Actually, it’s larger than a prokaryotic cell, and it also has a nucleus. Therefore, this organism belongs to the domain Eukarya, the domain that includes humans. This particular eukaryote is one of the smallest, simplest organisms in the domain, called a protist. It’s scientific name is Giardia lamblia. As a human parasite, it can make us sick. Kingdom Protista Protists are a group of all the eukaryotes that are not fungi, animals, or plants. As a result, it is a very diverse group of organisms. The eukaryotes that make up this kingdom, Kingdom Protista, do not have much in common besides a relatively simple organization. Protists can look very different from each other. Some are tiny and unicellular, like an amoeba, and some are large and multicellular, like seaweed. However, multicellular protists do not have highly specialized tissues or organs. This simple cellular-level organization distinguishes protists from other eukaryotes, such as fungi, animals, and plants. There are thought to be between 60,000 and 200,000 protist species, and many have yet to be identified. Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems. Other protists are responsible for a range of serious human diseases, such as malaria and sleeping sickness. The term protista was first used by Ernst Haeckel in 1866. Protists were traditionally placed into one of several groups based on similarities to a plant, animal, or fungus: the animal-like protozoa, the plant-like protophyta (mostly algae), and the fungus-like slime molds and water molds. These traditional subdivisions, which were 3 1.1. Protist Kingdom www.ck12.org largely based on non-scientific characteristics, have been replaced by classifications based on phylogenetics (evo- lutionary relatedness among organisms). However, the older terms are still used as informal names to describe the general characteristics of various protists. FIGURE 1.1 Protists range from single-celled amoe- bas to multicellular seaweed. Protists may be similar to animals, plants, or fungi. Summary • Kingdom Protista includes all eukaryotes that are not animals, plants, or fungi. • Kingdom Protista is very diverse.

Protist Evolution www.ck12.org 1.2 Protist Evolution • Outline the evolution of protists. • Explain the formation of the first eukaryotic cells. • Site evidence for the endosymbiotic theory. What’s the difference between a bacterium and a simple protist? Were simple protists the first eukaryotic organisms to evolve? Probably. A protist is a eukaryote, so each cell has a nucleus. Otherwise, simple protists, like the Paramecium and amoeba, can be fairly similar to bacteria. Evolution of Protists Scientists think that protists are the oldest eukaryotes. If so, they must have evolved from prokaryotic cells. How did this happen? The endosymbiotic theory provides the most widely-accepted explanation. That’s because it is well supported by evidence. The First Eukaryotic Cells According to the endosymbiotic theory, the first eukaryotic cells evolved from a symbiotic relationship between two or more prokaryotic cells. Smaller prokaryotic cells were engulfed by (or invaded) larger prokaryotic cells. The small cells (now called endosymbionts) benefited from the relationship by getting a safe home and nutrients. The large cells (now called hosts) benefited by getting some of the organic molecules or energy released by the endosymbionts. Eventually, the endosymbionts evolved into organelles of the host cells. After that, neither could live without the other. 6 www.ck12.org Chapter 1. Protists and Fungi As shown in Figure 1.2, some of the endosymbionts were aerobic bacteria. They were specialized to break down chemicals and release energy. They evolved into the mitochondria of eukaryotic cells. Some of the small cells were cyanobacteria. They were specialized for photosynthesis. They evolved into the chloroplasts of eukaryotic cells. FIGURE 1.2 Endosymbiotic theory explains how eukaryotic cells arose. Evidence for the Endosymbiotic Theory Many pieces of evidence support the endosymbiotic theory. For example: • Mitochondria and chloroplasts contain DNA that is different from the DNA found in the cell nucleus. Instead, it is similar to the circular DNA of bacteria. • Mitochondria and chloroplasts are surrounded by their own plasma membranes, which are similar to bacterial membranes. • New mitochondria and chloroplasts are produced through a process similar to binary fission. Bacteria also reproduce through binary fission. • The internal structure and biochemistry of chloroplasts is very similar to that of cyanobacteria. Summary • Scientists think that protists are the oldest eukaryotes. • Protists most likely evolved from prokaryotic cells, as explained by the endosymbiotic theory. This theory is well-supported by evidence. Explore More Use this resource to answer the questions that follow. 7 1.2.

New evidence inferred from phylogenetic analyses of nuclear ribosomal DNA sequence data together with abroad taxon sampling at family level suggest that the fungus is amember of Extremaceaeand therefore its previous placement within the broadly defined Teratosphaeriaceae was not supported. Anew genus Castanedospora is introduced to accommodate this species on the basis of its distinct morphology and phylogenetic position distant from Sporidesmiaceae sensu stricto in Sordariomycetes. The holotype material from Cuba was found to be exhausted and the Florida specimen, which agrees well with the original description, is selected as epitype.

From Roland Thaxter to the Present: Synergy Among Mycologists, Entomologists, Parasitologists Laboulbeniales were discovered in the middle of the 19th century, rather late in mycological history (Anonymous, 1849; Rouget, 1850; Robin, 1852, 1853; Mayr, 1853). After their discovery and eventually their recognition as fungi, occasional reports increased species numbers and broadened host ranges and geographical distributions; however, it was not until the fundamental work of Thaxter (1896, 1908, 1924, 1926, 1931), who made numerous collections but also acquired infected insects from correspondents, that the Laboulbeniales became better known among mycologists and entomologists. Thaxter set the stage for progress by describing a remarkable number of taxa: 103 genera and 1260 species. Fewer than 25 species of Pyxidiophora in the Pyxidiophorales are known. Many have been collected rarely, often described from single collections and never encountered again. They probably are more common and diverse than known collections indicate, but their rapid development in hidden habitats and difficulty of cultivation make species of Pyxidiophora easily overlooked and, thus, underreported (Blackwell and Malloch, 1989a,b; Malloch and Blackwell, 1993; Jacobs et al., 2005; Gams and Arnold, 2007).

Five corticolous lichen species (four foliose and one fruticose) and the leaf and bark tissues of their host trees were screened for the presence of asympto- matic, culturable microfungi. Four isolation procedures were evaluated to identify the most suitable one for isolating the internal mycobiota of lichens. A total of 242 isolates of 21 fungal genera were recovered from 500 thallus segments of the lichens. Different fungi dominated the fungal assemblages of the lichen thalli and the host tissues. An ordination analysis showed that there was little overlap between the fungi of the lichens and those of the host tissues even though, con- sidering their close proximity, they must have been exposed to the same fungal inoculum. This is the first study that compares the microfungal assemblage asso- ciated with lichens with those occurring in their substrates.

Nadine Lihach, who took care of the admissions, reports that we blew away last year's record attendance by about 140 people. Add to that all the volunteers who put the show together, and we had well over 900 people involved. That's a huge event for our club. Nadine said, "... this was a record year at the entry gate: 862 attendees (includes children). Our previous high was in 2013: 723 attendees. Success is more measured in the happiness index of those attending, and many people stopped by on their way out to thank us for the wonderful show. Kids—and there were many—were especially delighted, and I'm sure there were some future mycophiles and mycologists in Sunday's crowd.

    2006 Summer Workshop in Fungal Biology for High School Teachers Hibbett lab, Biology Department, Clark University Introduction to Fungal Biology—Morphology, Phylogeny, and Ecology General features of Fungi Fungi are very diverse. It is hard to define what a fungus is using only morphological criteria. Features shared by all fungi: • Eukaryotic cell structure (but some have highly reduced mitochondria) • Heterotrophic nutritional mode—meaning that they must ingest organic compounds for their carbon nutrition (but some live in close symbioses with photosynthetic algae—these are lichens) • Absorptive nutrition—meaning that they digest organic compounds with enzymes that are secreted extracellularly, and take up relatively simple, small molecules (e.g., sugars). • Cell walls composed of chitin—a polymer of nitrogen-containing sugars that is also found in the exoskeletons of arthropods. • Typically reproduce and disperse via spores Variable features of fungi: • Unicellular or multicellular—unicellular forms are called yeasts, multicellular forms are composed of filaments called hyphae. • With or without complex, multicellular fruiting bodies (reproductive structures) • Sexual or asexual reproduction • With or without flagella—if they have flagella, then these are the same as all other eukaryotic flagellae (i.e., with the “9+2” arrangement of microtubules, ensheathed by the plasma membrane) • Occur on land (including deserts) or in aquatic habitats (including deep-sea thermal vent communities) • Function as decomposers of dead organic matter or as symbionts of other living organisms—the latter include mutualists, pathogens, parasites, and commensals (examples to be given later) Familiar examples of fungi include mushrooms, molds, yeasts, lichens, puffballs, bracket fungi, and others. There are about 70,000 described species of fungi.

    Marine Fungi: Some Factors Influencing Biodiversity

    Fungal Diversity Marine fungi: some factors influencing biodiversity E.B. Gareth Jones I Department of Biology and Chemistry, City University of Hong Kong, 83 Tat Chee Avenue, Kowloon, Hong Kong, and BIOTEC, National Center for Genetic Engineering and Biotechnology, 73/1 Rama 6 Road, Bangkok 10400, Thailand; e-mail: [email protected] Jones, E.B.G. (2000). Marine fungi: some factors influencing biodiversity. Fungal Diversity 4: 53-73. This paper reviews some of the factors that affect fungal diversity in the marine milieu. Although total biodiversity is not affected by the available habitats, species composition is. For example, members of the Halosphaeriales commonly occur on submerged timber, while intertidal mangrove wood supports a wide range of Loculoascomycetes. The availability of substrata for colonization greatly affects species diversity. Mature mangroves yield a rich species diversity while exposed shores or depauperate habitats support few fungi. The availability of fungal propagules in the sea on substratum colonization is poorly researched. However, Halophytophthora species and thraustochytrids in mangroves rapidly colonize leaf material. Fungal diversity is greatly affected by the nature of the substratum. Lignocellulosic materials yield the greatest diversity, in contrast to a few species colonizing calcareous materials or sand grains. The nature of the substratum can have a major effect on the fungi colonizing it, even from one timber species to the next. Competition between fungi can markedly affect fungal diversity, and species composition. Temperature plays a major role in the geographical distribution of marine fungi with species that are typically tropical (e.g. Antennospora quadricornuta and Halosarpheia ratnagiriensis), temperate (e.g. Ceriosporopsis trullifera and Ondiniella torquata), arctic (e.g.

Local conditions, such as high temperature, heavy rainfall, and humidity, promote fungal growth leading to increased occurrence of mycotoxins in spices. Moreover, the lack of good agricultural practice (GAP), good manufacturing practice (GMP), and good hygienic practice (GHP) in developing countries are of great concern. This review summarizes recent data from a total of 56 original papers dealing with mycotoxins and microfungi in various spices in the last five years. A total of 38 kinds of spices, 17 mycotoxins, and 14 microfungi are discussed in the review. Worldwide, spices are rather overlooked in terms of mycotoxin regulations, which usually only cover aflatoxins (AFs) and ochratoxin A (OTA).
