More than 800 species of fungi are described as pathogens of insects and other arthropods. Many of them play a significant role in the natural regulation of insect and mite populations. The best known representatives belong to the anamorphic fungi (Deuteromycota), to the Clavicipetales (...
There are spore-like bodies and filaments in Precambrian rocks that may represent the remains of fungi, but the affinities of some of them remain equivocal. For example, although initially described as septate fungal filaments, Eomycetopsis robusta (Schopf, 1968), (FIG. 2.32) from the ...
They have been found to display some fungal characteristics, and phylogenetic studies suggest that they are related to fungi, either as a basal branch or sister group. The Blastocladiomycota and Chytridiomycota, named the lower fungi, historically were described together; however, molecular ...
Cantharellus zangii is described and illustrated from subalpine forest (>3000 m) in northwestern Yunnan, China. The diagnostic characteristics of C. zangii... XF Tian,B Buyck,SC Shao,... - 《Mycotaxon》 被引量: 21发表: 2012年 Characterization of Fusarium oxysporum f. sp. melongenae isolates...
While low-molecular-weight constituents are regularly uncovered as constitutive defense agents against microbial attack, there is also good evidence that proteins are also present, or are induced, to provide protection. Various chitinases and “pathogenesis-related” proteins have been described.159 More...
The roots were gently washed under running tap water to remove residues of the cultivation substrate and treated as described above for the naturally colonized roots, including microscopy. Three small pieces of the cultivation substrate were extracted from each vessel and placed on the surface of ...
Scientists' intrigue with fungi is twofold: the fungus in our bodies could hold crucial answers about the behavior of cancer cells, and the benefits of medicinal mushrooms are promising.
Summary This chapter contains sections titled: What are fungi? The structure of the fungal cell Medical significance of fungi Fungal species identification methods Antifungal therapy Mechanisms of antifungal drug resistance Some clinically important fungi Antibiotic production by fungi Genetic manipulation of ...
Those habitats often are characterized by high concentrations of dissolved sulfates and iron as well as hydrogen ions. Microorganisms whose pH optima for growth exceed pH 8, usually falling between 9 and 10, are defined as alkalophiles. Although the majority of the organisms described as growing...
Species are delimited on the basis of zoospore ultrastructure (Ho and Barr 1995) and source of the isolate. Using those characters, 17 species in six genera have been described in the literature; however, only five genera have been recognized since the synonomy of Ruminomyces (Anaeromyces) ...
