Barley reaction to Cochliobolus sativus based on detached first leaf
Australasian Plant Pathology - Tập 36 - Trang 475-477 - 2007
M. I. E. Arabi, M. Jawhar
Spot blotch, caused by Cochliobolus sativus, is a common foliar disease of barley that is controlled primarily through the development of resistant cultivars. An assay involving the inoculation of a detached first leaf (DFL) maintained in vitro was used to determine the reaction of five barley genotypes to the disease. The estimation of the infected leaf area enabled discrimination among barley ge...... hiện toàn bộ
Molecular characterisation and pathogenicity of Erysiphe graminis f.sp. hordei in Australia
Australasian Plant Pathology - Tập 25 - Trang 55-63 - 1996
Dara L. Whisson
Pathogenicity analysis of Australian isolates of Erysiphe graminis f.sp. hordei on a set of barley lines, near-isogenic for powdery mildew resistance, and RFLP analyses of the DNA from these isolates showed only minor differences between them. The study also revealed that many ‘unnecessary genes’ for virulence have been retained. The isolates of E. graminis contained a significant quantity of dsRN...... hiện toàn bộ
Colletotrichum truncatum Pathosystem on Capsicum spp: infection, colonization and defence mechanisms
Australasian Plant Pathology - Tập 41 - Trang 463-473 - 2012
N. P. Ranathunge, O. Mongkolporn, R. Ford, P. W. J. Taylor
The disease cycle of the chili (Capsicum annuum) anthracnose fungus Colletotrichum truncatum (formerly C. capsici) was elucidated from a study of infection and colonization of seed, leaves and fruit. Microscopic observations of detached leaves and fruit inoculated with a virulent pathotype (F83B), revealed direct cuticle penetration and, intramural, endophytic and necrotrophic phases of colonizati...... hiện toàn bộ
Rapid identification of a second outbreak of asiatic citrus canker in the Northern Territory using the polymerase chain reaction and genomic fingerprinting
Australasian Plant Pathology - Tập 24 - Trang 104-111 - 1995
M. R. Gillings, P. C. Fahy, P. Broadbent, D. Barnes
In May 1993, symptoms of asiatic citrus canker were found on West Indian lime, lemon and grapefruit trees in a mixed citrus orchard at Lambell’s Lagoon, near Darwin, Northern Territory, close to the site of a previous (1991) canker outbreak. Symptoms occurred on the spring growth flush at the start of the wet season (October 1992). The time lag between the appearance of symptoms and collection of ...... hiện toàn bộ
Observations on the control of the silver leaf fungus (Chondrostereum purpureum) by Difolatan in vitro
Australasian Plant Pathology - Tập 9 - Trang 5-6 - 1980

Molecular evidence for existence of a New World begomovirus associated with yellow mosaic disease ofCorchorus capsularis in India
Australasian Plant Pathology - Tập 3 - Trang 59-62 - 2008
R. Ghosh, S. Paul, S. Das, P. Palit, S. Acharyya, A. Das, J. I. Mir, S. K. Ghosh, A. Roy
Yellow mosaic disease of jute (Corchorus capsularis) was found to be associated with a whitefly-vectored begomovirus. Sequencing of part of the begomovirus DNA-A indicated the presence of a New World begomovirus which has been detected for the first time in India.
Cloning and development of pathotype-specific SCAR marker associated with Sclerospora graminicola isolates from pearl millet
Australasian Plant Pathology - Tập 38 - Trang 216-221 - 2009
J. Sudisha, S. Ananda Kumar, S. R. Niranjana, N. P. Shetty, H. Shekar Shetty
Downy mildew pathogen of pearl millet in India is associated with the spread of the highly virulent Sclerospora graminicola pathotype-1. Twenty-seven S. graminicola isolates were screened using 20 inter simple sequence repeats (ISSR). Dinucleotide repeat primer [17898A-(CA)6 AC] amplified a ∼600 bp fragment specific to five isolates of pathotype-1 (Sg 048, Sg 153, Sg 212, DM-11 and DM-90). The ISS...... hiện toàn bộ
Occurrence of barley yellow dwarf viruses in over-summering grasses and cereal crops in Western Australia
Australasian Plant Pathology - Tập 19 - Trang 90-96 - 1990
R. A. C. Jones, S. J. McKirdy, R. G. Shivas
During summer and early autumn in 1989, barley yellow dwarf viruses (BYDV) were detected by ELISA in grasses collected at 72 sites in the south-west of Western Australia. Most of the grasses sampled survived the dry conditions in roadside ditches or at the edges of creeks. BYDV was found at ten or more sites in each of five perennial species, Cynodon dactylon, Ehrharta calycina, Eragrostis curvula...... hiện toàn bộ
Foliar Phytophthora in New Zealand plantation forests: historical presence of Phytophthora kernoviae and association with a previously undiagnosed disorder of Pinus radiata
Australasian Plant Pathology - Tập 50 - Trang 747-759 - 2021
Rebecca L. McDougal, Rebecca J. Ganley
Two foliar Phytophthora species are impacting New Zealand’s pine forests. Both Phytophthora pluvialis and Phytophthora kernoviae cause similar symptoms on pine needles, however P. pluvialis is a recent arrival to New Zealand and is the primary cause of red needle cast disease in Pinus radiata. The objective of this study was to determine if Phytophthora species could be detected in archived foliag...... hiện toàn bộ
A review of the methodology to detect and identify Karnal bunt—a serious biosecurity threat
Australasian Plant Pathology - Tập 42 - Trang 95-102 - 2012
Mui-Keng Tan, John P. Brennan, Dominie Wright, Gordon M. Murray
Tilletia indica, the cause of Karnal bunt of wheat, replaces part of the seed with a black powdery mass containing millions of spores and produces a strong unpleasant odour like rotten fish. The fishy smell has serious consequences for the marketability of wheat. The fungus is thus subjected to very strict quarantine regulations in countries not known to have the pathogen. The pat...... hiện toàn bộ
