morpho molecular characterization of two ampelomyces spp pleosporales strains Mycoparasites of powdery mildew of hevea brasiliensis
Frontiers in Microbiology, 2018Co-Authors: Kapila K. Liyanage, Sehroon Khan, Siraprapa Brooks, Peter E. Mortimer, Samantha C. Karunarathna, Kevin D HydeAbstract:Powdery mildew disease of rubber affects immature green leaves, buds, inflorescences, and other immature tissues of rubber trees, resulting in up to 45% losses in rubber latex yield worldwide. The disease is often controlled by dusting the diseased plants with powdered sulphur, which can have long-term negative effects on the environment. Therefore, it is necessary to search for alternative and environmentally friendly control methods for this disease. This study aimed to identify Mycoparasites associated with rubber powdery mildew species, and characterize them on the basis of morpho-molecular characteristics and phylogenetic analyses of ITS rDNA regions. We observed that the Ampelomyces fungus parasitizes rubber powdery mildew, and eventually destroys it. Furthermore, on the basis of phylogenetic analyses and morphological characteristics we confirmed that the Ampelomyces Mycoparasite isolated from rubber powdery mildew is closely related to other mycohost taxa in the Erysiphe genus. A total of 73 (71 retrieved from GenBank and two obtained from fresh collections of rubber powdery mildew fungi) Ampelomyces sp. were analysed using ITS rDNA sequences and 153 polymorphic sites were identified through haplotypic analyses. A total of 28 haplotypes (H1-H28) were identified to have a complex network of mutation events. The results from phylogenetic tree constructed on the basis of maximum likelihood analyses, and the haplotype network tree revealed similar relationships of clustering pattern. This work presents the first report of Ampelomyces sp. as a potential biocontrol against powdery mildew disease of rubber. This work presents a potential biocontrol agent against rubber powdery mildews, which could be an alternative to synthetic chemical fungicides

Pythium periplocum, an aggressive Mycoparasite of Botrytis cinerea causing the gray mould disease of grape-vine
FEMS microbiology letters, 1999Co-Authors: Bernard PaulAbstract:Pythium periplocum Dreschler has been found to be an aggressive Mycoparasite of Botrytis cinerea, the causal agent of the gray mould disease of the grape-vine. When grown together, the former enters the latter's mycelium, branches freely within, coagulates its cytoplasm and finally tears its hyphae apart, bringing about widespread destruction of the grape-vine pathogen. Extensive coiling around the host, as reported in the case of other Mycoparasites belonging to the genus Pythium, has not been observed here. The infected mycelium of B. cinerea fails to infect the grape-vine and does not induce the characteristic gray mould symptoms. Since P. periplocum is not a grape-vine parasite, it could be useful for the biological control of B. cinerea. A brief account of this mycoparasitism is discussed in this article.

Suppression of Botrytis cinerea causing the grey mould disease of grape-vine by an aggressive Mycoparasite, Pythium radiosum
FEMS Microbiology Letters, 1999Co-Authors: Bernard PaulAbstract:Pythium radiosum Paul has been found to be an aggressive Mycoparasite of Botrytis cinerea which causes grey mould disease on the grape-vine. The mycoparasitic fungus enters the host mycelium, coagulates its protoplasm, empties its contents and finally comes out producing numerous ramifications and sexual structures. When the infected mycelium of B. cinerea is applied to the leaves of the grape-vine, the characteristic grey mould symptoms fail to appear. Since P. radiosum causes no harm to the grape-vine, it can be used as a biological control agent against B. cinerea. A brief account of the Mycoparasite and its antagonism towards B. cinerea is discussed here.
