Microsatellite markers have been extensively utilised in the leguminosae for genome mapping and identifying major loci governing traits of interest for eventual marker-assisted selection (MAS). The lack of available lentil-specific microsatellite sequences and gene-based markers instigated the mining and transfer of expressed sequence tag simple sequence(More)
Resistance to anthracnose, caused by Colletotrichum capsici and C. acutatum, was investigated in Capsicum baccatum PBC80 and PBC1422 and C. chinense PBC932. Mature green and ripe fruit were inoculated with 13 isolates of the two Colletotrichum species PBC80 contained the broadest spectrum of resistance to both Colletotrichum species because none of the(More)
An intraspecific linkage map of the chickpea genome based on STMS as anchor markers, was established using an F(2) population of chickpea cultivars with contrasting disease reactions to Ascochyta rabiei (Pass.) Lab. At a LOD-score of 2.0 and a maximum recombination distance of 20 cM, 51 out of 54 chickpea-STMS markers (94.4%), three ISSR markers (100%) and(More)
The genomes of Chrysoporthe austroafricana, Diplodia scrobiculata, Fusarium nygami, Leptographium lundbergii, Limonomyces culmigenus, Stagonosporopsis tanaceti, and Thielaviopsis punctulata are presented in this genome announcement. These seven genomes are from endophytes, plant pathogens and economically important fungal species. The genome sizes range(More)
The first intraspecific linkage map of the lentil genome was constructed with 114 molecular markers (100 RAPD, 11 ISSR and three RGA) using an F(2) population developed from a cross between lentil cultivars ILL5588 and ILL7537 which differed in resistance for ascochyta blight. Linkage analysis at a LOD score of 4.0 and a maximum recombination fraction of(More)
Ray blight disease of pyrethrum (Tanacetum cinerariifolium) is shown to be caused by more than one species of Stagonosporopsis. The Australian pathogen, previously identified as Phoma ligulicola var. inoxydabilis, represents a new species described as Stagonosporopsis tanaceti based on morphological characters and a five-gene phylogeny employing partial(More)
SUMMARY A genome linkage map was developed for Ascochyta rabiei (Pass.) Labrousse, (teleomorph) Didymella rabiei (Kovachevski), an important pathogen causing ascochyta blight in chickpea (Cicer arietinum L.). The map was constructed using 96 progeny generated from a single pseudothecium produced from a cross between a USA MAT-2 isolate and an Australian(More)
Random amplified polymorphic DNA (RAPD) analysis using 10-mer oligonucleotide primers efficiently differentiated sugarcane cultivars and proved suitable for detecting gross genetic change such as that which can occur in sugarcane subjected to prolonged tissue culture, for example in protoplast-derived callus. However, RAPD analysis was not sufficiently(More)
Novel species of fungi described in the present study include the following from Australia: Neoseptorioides eucalypti gen. & sp. nov. from Eucalyptus radiata leaves, Phytophthora gondwanensis from soil, Diaporthe tulliensis from rotted stem ends of Theobroma cacao fruit, Diaporthe vawdreyi from fruit rot of Psidium guajava, Magnaporthiopsis agrostidis from(More)
Ascochyta blight of lentil (Lens culinaris ssp. culinaris) is caused by Ascochyta lentis. The disease causes severe damage to all aerial parts of the plant and may lead to total crop loss during extremely severe epidemics. To identify qualitative differences in resistance within Australian lentil crops, variation in virulence was examined among 17 isolates(More)
