TL;DR: The nucleotide sequences of the nuclear ribosomal DNA including 18S, 5.8S, and 28S rDNA and the internal transcribed spacer regions were determined for 33 powdery mildew taxa spanning 15 genera to ...
Abstract: The nucleotide sequences of the nuclear ribosomal DNA including 18S, 5.8S, and 28S rDNA and the internal transcribed spacer regions were determined for 33 powdery mildew taxa spanning 15 genera to ...
TL;DR: It is demonstrated that Ampelomyces hyperparasite is indeed an assemblage of several distinct lineages rather than a sole species, and the isolates show not only some degree of host specialization but also adaptation to their mycohosts during the evolution of the hyperParasite.
TL;DR: Analyses of morphological traits and molecular sequence data led to identifications of the causal agents of the powdery mildew diseases involved, and a new species of Phyllactinia on Mimosa malacophylla is described, morphologically similar to P. dalbergiae but readily distinguishable by differences in the asexual morph.
TL;DR: Twenty one plant species were screened in vitro for their fungitoxic properties against four fungal pathogens viz., Phyllactinia corylea, Peridiopsora mori and Pseudocercospora mori by slide germination method and Myrothecium roridum by poisoned food technique.
Abstract: Twenty one plant species were screened in vitro for their fungitoxic properties against four fungal pathogens viz., Phyllactinia corylea (Powdery mildew), Peridiopsora mori (Brown rust) and Pseudocercospora mori (Black leaf spot) by slide germination method and Myrothecium roridum (Brown leaf spot) by poisoned food technique. Conidial germination of P. corylea was significantly reduced in 5% (w/v) ethanolic extracts all tested plant. Extract of Cassia tora and Cassia sophera completely inhibited conidial germination of P. corylea. Other effective plant extracts inhibited > 90% germination were Allium sativum (99.56%), Ocimum sanctum (97.80%), Moringa oleifera (97.32%). Conidial germination of Pseudocercospora mori was completely inhibited in extract of A. sativum and D. metel. More than 90% inhibition was observed with extract of Holarrhena antidysentrica (93.10%), Adhatoda Zeylanica (91.40%) and Calotropis gigentia (90.40%). Urediniospore germination of Peridiopsora mori was significantly reduced in 19 p...
