“…They also found T. harzianum the most genetically diverse speices, with the T. harzianum complex representing the majority of isolates. A similar study was conducted by Kubicek et al (2003) in Southeast Asia, where they reported T. asperellum, T.atroviride, T. ghanense, T. hamatum, T. harzianum, T. koningii, T. spirale, T. virens, T. viride and H. jecorina (anam: T. reesei), along with seven new species among 96 isolates tested . The T. harzianum complex was equally prevalent, exhibiting high metabolic and morphological variability that may explain the wide distribution of this species aggregate over different habitats .…”

“…Berg et al (2005) or in South-East Asia (Kubicek et al, 2003) and South America . All indigenous Hypocrea/Trichoderma species are cosmopolitan with an extraordinarily high antagonistic potential against fungal pathogens, and many of them are already known from many locations in Eurasia and Africa (Kubicek et al, 2003). In comparison with the whole fungal community, Trichoderma-specific communities showed a low diversity and no correlation to plant communities or abiotic factors.…”

Fungal diversity in the rhizosphere of endemic plant species of Tenerife (Canary Islands): relationship to vegetation zones and environmental factors

Knowledge about fungal diversity scaling relationships relative to that of plants is important to understand ecosystem functioning. Tenerife Island, a natural laboratory to study terrestrial biodiversity, is represented by six different vegetation zones characterized by specific abiotic conditions and plant communities with a high proportion of endemic plants. Little is known about the biodiversity of associated fungi. To understand the relationship between plant and fungal communities, we analysed soil/rhizosphere fungi from all vegetation zones. From 12 sampling points dispersed on the whole island, molecular analysis of fungal communities was determined by single-strand conformation polymorphism (SSCP) analysis using universal and specific primers for Trichoderma. The highly diverse fungal communities were mainly characterized by ectomycorrhizaforming Basidiomycota and a high proportion of yet-unidentified species. Besides, Trichodermaspecific SSCP resulted in low diversity of mainly cosmopolitan species, for example Hypocrea lixii/ T. harzianum. The dominance of T. harzianum was confirmed by cultivation. All Trichoderma isolates show an extraordinarily high antagonistic potential towards different groups of plant pathogens, supporting the hypothesis of extensive colonization by highly competitive Trichoderma species from the continent. In contrast, biodiversity patterns of the whole fungal and plant communities follow the same ecological rules. Furthermore, a high statistical correlation between fungal communities and the main environmental factors, temperature and precipitation, was found.

“…For species of genus Hypocrea/Trichoderma, rapid growth as well as ability to assimilate diverse substrates is a great advantage that allows this genus to colonize many ecological niches in the world. Kubicek et al (2003) compared the inter-specific variability of carbon source utilisation profiles in Hypocrea/ Trichoderma, and confirmed that isolates of most species formed defined clusters, thus proving the applicability of this method in species identification. This approach was then integrated in a description of T. brevicompactum sp.…”

“…The Phenotype MicroArray™ (PM) system (Bochner et al, 2001;Bochner, 1988;2003) (Biolog Inc., Hayward, CA), however, offers a reasonable compromise and has frequently been used for the analysis of bacteria and yeast mutant strains (http://www.biolog.com/mID_section_13.html for bibliography). Kubicek et al (2003) applied carbon source PMs to soil fungi, thereby detecting species-diagnostic characters in a collection of Trichoderma (teleomorph Hypocrea) isolates from Southeast Asia. Tanzer et al (2003) demonstrated how global nutrient utilization analysis can be used to elucidate the effects of either genetic alterations or chemical treatments on Aspergillus nidulans, Aspergillus fumigatus, Magnaporthe grisea, and Mycosphaerella graminicola.…”

Abstract:Conidial fungi or molds and mildews are widely used in modern biotechnology as producers of antibiotics and other secondary metabolites, industrially important enzymes, chemicals and food. They are also important pathogens of animals including humans and agricultural crops. These various applications and extremely versatile natural phenotypes have led to the constantly growing list of complete genomes which are now available. Functional genomics and proteomics widely exploit the genomic information to study the cell-wide impact of altered genes on the phenotype of an organism and its function. This allows for global analysis of the information flow from DNA to RNA to protein, but it is usually not sufficient for the description of the global phenotype of an organism. More recently, Phenotype MicroArray (PM) technology has been introduced as a tool to characterize the metabolism of a (wild) fungal strain or a mutant. In this article, we review the background of PM applications for fungi and the methodic requirements to obtain reliable results. We also report examples of the versatility of this tool.
