Phylogenetic studies based on the 18S rDNA sequence analysis suggest that Trichoderma is a monophyletic branch within the Hypocreaceae (Kullnig-Gradinger et al. Selected illustrations: Comp. 17.11) are particularly common on Stereum species (Samuels 1976; Seifert 1985). In: Chang ST, Buswell JA, Miles PG (eds) Genetics and breeding of edible mushrooms. The nutrients provide nutrition and signal to regulate hydrolases expression (Suto and Tomita, 2001). It is also probable that many new species associated with aquatic animals will be uncovered as mycotic investigations intensify, especially in little-studied regions or biological communities. Dufour et al. Formation of ascospores: Asci are unconjugated, and form one or two, rarely three or four, spherical, roughened spores (Fig. After a series of polymorphic markers has been identified, the markers can be cloned, sequenced, and used as a basis for designing marker-specific PCR primers for dual-primer PCR (dpPCR) analysis, which permits rapid assessment of populations for levels of genetic diversity. That cases of mycotoxicoses and populations of their causative species likely will increase is of considerable concern (Rand 1996) as the aquaculture industry expands to include new and exotic species and moves into new geographic areas. 2006, Visser et al. Through progress in biochemistry and molecular genetics—particularly the “omics” sciences, the analysis of high-throughput gene expression data, and comparisons of Trichoderma genomes and metabolism, a better understanding of the evolution, biology, and physiology of these fungi has been reached (Kubicek et al., 2011; Martinez et al., 2008; Schmoll, 2008).This chapter reviews the knowledge of these issues generated in recent years. Several Saprochaete species produce remarkably large, somewhat alga-like thalli (Fig. The author is very grateful to the editors of the special issue for providing the space for this opinion dealing with a matter which is not much important in itself, but only by the need of defending a little piece of scientific freedom and thinking. TABLE 26.1. Rifai (1969) proposed and defined nine morphological species aggregates. By using our services, you agree to our use of cookies. Also, genetic diversity among Trichoderma spp. Infection seems relatively prevalent in aquatic snake species (Erpeton tentaculatum, Nerodia spp., Acrochordus spp.) This situation will become less problematic as the results of molecular characterization and their application to fungal systematics become more widespread.

Wu et al. 1996) and awaiting additional analysis (Ragan et al., unpublished data). The Ascomycota comprise the largest division of fungi including approximately 3250 genera containing 32,250 recognized species (Hawksworth et al. 1994; Ospina-Giraldo et al. The sensitivity of apPCR is such that small amounts of fungal material (0.5 cm3) are sufficient for hundreds to thousands of genetic analyses (e.g., see Fig. and compared with traditional classifications. However, it has been demonstrated that fragments significantly smaller than spores (down to 0.1 μm) are released from the mycelia of infested materials.22–25 These fragments can be liberated in numbers hundreds of times higher than the number of spores, with no correlation between the numbers of released fragments and spores.23 It is important to consider exposure to the small fungal fragments when assessing exposure to fungal allergens.
