“…Primers and probes built to take advantage of the presence of unique differences in such retrotransposon sequences can be useful for strain/race identification. Examples include the work by Sastryet al [ 57 ] with S. graminicola and Becker et al [ 58 ] in the basidiomycete Chondrostereum purpureum .…”

Simple sequence repeat markers useful for sorghum downy mildew (Peronosclerospora sorghi) and related species

Background: A recent outbreak of sorghum downy mildew in Texas has led to the discovery of both metalaxyl resistance and a new pathotype in the causal organism, Peronosclerospora sorghi. These observations and the difficulty in resolving among phylogenetically related downy mildew pathogens dramatically point out the need for simply scored markers in order to differentiate among isolates and species, and to study the population structure within these obligate oomycetes. Here we present the initial results from the use of a biotin capture method to discover, clone and develop PCR primers that permit the use of simple sequence repeats (microsatellites) to detect differences at the DNA level.

“…Retrotransposable elements have been found to play an important role in shaping eukaryotic DNA, and their activity and turnover rate directly influence the size of genomes. These molecules have been described in different fungi 18–20 . A dispersed repeated DNA sequence isolated from the filamentous fungus Cryphonectria parasitica was shown to be very useful in DNA fingerprinting and in the analysis of the population structure of this chestnut pathogen 21 .…”

A dihydropyridine derivative, diethyl 4-(4-methoxyphenyl)-2,6-dimethyl-1,4-dihydropyridin-3,5-dicarboxylate (2e), having potent antifungal activity against pathogenic species of Aspergillus was investigated for its possible molecular mechanism of action. The SDS-PAGE coupled with nano-high-performance liquid chromatography-tandem mass spectrometry was used directly to assess both absolute abundance and differential expression of proteins in the secretory phases of Aspergillus fumigatus under the influence of 2e. It was observed that the compound inhibited the expression of two proteins of 60.99 and 79.77 kDa. Both of these secretory proteins that were inhibited by 2e, were analysed further by matrix assisted laser desorption ionization time-of-flight mass spectrometry. The 60.99- and 79.77-kDa proteins were identified as probable retroelement pol polyprotein and elongation factor G respectively. These targeted proteins could be the products of potentially virulence-related genes of A. fumigatus which may unravel the mode of action of 2e and pathobiology of A. fumigatus.

“…purpureum occurs commonly in boreal and temperate vegetation zones and is also present in New Zealand as an introduced species (Ramsfield et al 1996). The populations between Europe and North America belong to the same biological species, but molecular markers show certain levels of differentiation between the continents, while intracontinental population differences are small (Becker et al 2004(Becker et al , 2005Gosselin et al 1996Gosselin et al , 1999Ramsfield et al 1996Ramsfield et al , 1999Vartiamäki et al 2008b).…”

“…Therefore, the population genetics of the control fungus should be understood before widespread control actions are conducted. As pointed out above, the populations of C. purpureum have been studied in northern Europe and North America, and in both continents the degree of genetic variation is high, but differentiation between populations is small (Becker et al 2004(Becker et al , 2005Gosselin et al 1996Gosselin et al , 1999Ramsfield et al 1996Ramsfield et al , 1999Vartiamäki et al 2008b). Therefore, either a gene flow occurs naturally over large geographic distances, or the population size of the fungus is so large in both continents that the frequencies of selectively neutral genes change extremely slowly.…”

“…As genetic differences between C. purpureum on different continents are obvious despite their biological conspecificity , none of the control agents will probably be used globally. However, the low level of population differentiation (Becker et al 2004(Becker et al , 2005Gosselin et al 1996Gosselin et al , 1999Ramsfield et al 1996Ramsfield et al , 1999Vartiamäki et al 2008b) within continents allows the use of a single strain over large areas in Europe or North America. Also, development of resistance in hardwoods against any of these strains is unlikely due to the high frequency of natural infection.…”

A decay fungus, Chondrostereum purpureum (Pers. Ex Fr.) Pouzar, has been investigated in Europe, Northern America and New Zealand for its ability to decay hardwood stumps and thus prevent sprouting. The aim of these investigations has been to find an alternative to mechanical (cutting only) and chemical sprout control (cutting and applying chemicals to stumps in order to prevent sprouting). Mechanical sprout control is not an efficient option due to hardwood tree species’ ability to re-sprout efficiently after cutting, and therefore management costs are high. Chemicals would be efficient but due to their harmful effects on the environment, alternatives are needed. The fungal treatment, i.e., cutting accompanied with C. purpureum inoculum is an environmentally friendly and efficient option for sprout control. This mini-review comprises the role and function of C. purpureum in biocontrol of trees: the ecology of C. purpureum, its sprout control efficacy, factors affecting sprout control efficacy, devices in biological sprout control, potential risks, and the future perspectives of biological sprout control. Key points • A fungus Chondrostereum purpureum is efficient in preventing sprouting of hardwoods • C. purpureum is not sensitive to environmental conditions • Devices should be developed for cost-efficient biological sprout control
