Evolutionary Relationships between Rhynchosporium lolii sp. nov. and Other Rhynchosporium Species on Grasses
The fungal genus Rhynchosporium (causative agent of leaf blotch) contains several host-specialised species, including R. commune (colonising barley and brome-grass), R. agropyri (couch-grass), R. secalis (rye and triticale) and the more distantly related R. orthosporum (cocksfoot). This study used molecular fingerprinting, multilocus DNA sequence data, conidial morphology, host range tests and ...
متن کاملDifferences in MAT Gene Distribution and Expression between Rhynchosporium Species on Grasses
Leaf blotch is a globally important disease of barley crops and other grasses that is caused by at least five host-specialised species in the fungal genus Rhynchosporium. The pathogen R. commune (specialised to barley, brome-grass and Italian ryegrass) has long been considered to reproduce only by asexual means, but there has been accumulating evidence for recombination and gene flow from popul...
متن کاملTwo new species of Rhynchosporium.
Rhynchosporium consists of two species, R. secalis and R. orthosporum. Both are pathogens of grasses with R. secalis infecting a variety of Poaceae hosts and R. orthosporum infecting Dactylis glomerata. Phylogenetic analyses of multilocus DNA sequence data on R. secalis isolates originating from cultivated barley, rye, triticale and other grasses, including Agropyron spp., Bromus diandrus and H...
متن کاملCercosporoid fungi (Mycosphaerellaceae) 3. Species on monocots (Poaceae, true grasses)
The third part of a series of monographic treatments of cercosporoid fungi (formerly Cercospora s. lat., Mycosphaerellaceae, Ascomycota) continues with a treatment of taxa on monocots (Liliopsida; Equisetopsida, Magnoliidae, Lilianae), covering asexual and holomorph species with mycosphaerella-like sexual morphs on true grasses (Poaceae), which were excluded from the second part. The species co...
متن کاملDetection of the fumonisin-producing Fusarium fujikuroi species complex (FFSC) associated with wild grasses in Iran
In order to determine the fumonisin producingisolates of the Fusarium fujikuroi species complex (FFSC), associated with infected spikes, and ear rot of grass plants, we examined 78 samples collected from Kermanshah province, Iran. Based on morphological characters, twenty two isolates assigned to the FFSC and were identified as F. proliferatum (ten isolates), F. verticillioides (seven isolates)...
