Seed degeneration in potato: the need for an integrated seed health strategy to mitigate the problem in developing countries Tập 65 Số 1 - Trang 3-16 - 2016
S. Thomas‐Sharma, Abdulwahab Abdurahman, Sajid Ali, Jorge Andrade-Piedra, Siqin Bao, Amy O. Charkowski, Darren Crook, M. S. Kadian, Peter Kromann, P.C. Struik, L. Torrance, Karen A. Garrett, G. A. Forbes
Seed potato degeneration, the reduction in yield or quality caused by an
accumulation of pathogens and pests in planting material due to successive
cycles of vegetative propagation, has been a long‐standing production challenge
for potato growers around the world. In developed countries this problem has
been overcome by general access to and frequent use of seed, produced by
specialized growers, t... hiện toàn bộ
Elucidation of the infection process of Ustilaginoidea virens (teleomorph: Villosiclava virens) in rice spikelets Tập 62 Số 1 - Trang 1-8 - 2013
Tang Yu-qi, Jie Jin, Dongwei Hu, Mingli Yong, You‐Ping Xu, Lishan He
This study reports an efficient inoculation protocol that allowed cytological
analysis of the infection process of the rice false smut pathogen Ustilaginoidea
virens. Examination of serial semithin and ultrathin sections of infected
spikelets showed that the primary infection sites for the pathogen were the
upper parts of the three stamen filaments located between the ovary and the
lodicules. The ... hiện toàn bộ
Use of next‐generation sequencing for the identification and characterization of Maize chlorotic mottle virus and Sugarcane mosaic virus causing maize lethal necrosis in Kenya Tập 62 Số 4 - Trang 741-749 - 2013
Ian P. Adams, Douglas W. Miano, Z. M. Kinyua, Anne Wangai, Esther Kimani, Noah Phiri, Robert W. Reeder, V. Harju, R. Glover, U. Hany, Rose Souza-Richards, Palash Deb Nath, T. Nixon, Adrian Fox, A. V. Barnes, J. Smith, A. Skelton, Richard Thwaites, R. A. Mumford, Neil Boonham
The diagnosis of novel unidentified viral plant diseases can be problematic, as
the conventional methods such as real‐time PCR or ELISA may be too specific to a
particular species or even strain of a virus, whilst alternatives such as
electron microscopy (EM) or sap inoculation of indicator species do not usually
give species level diagnosis. Next‐generation sequencing (NGS) offers an
alternative ... hiện toàn bộ
Effects of calcium on biocontrol activity of yeast antagonists against the postharvest fungal pathogen Rhizopus stolonifer Tập 51 Số 3 - Trang 352-358 - 2002
Shiping Tian, Qing‐Hua Fan, Yanyan Xu, Aili Jiang
Calcium chloride (2% w/v) significantly inhibited the growth of the pathogen
Rhizopus stolonifer, but did not affect the colony‐forming units (CFU) of yeasts
Candida guilliermondii and Pichia membranefaciens in potato dextrose broth. The
concentration of yeast suspension influenced spore germination and germ tube
growth of R. stolonifer in vitro, as well as disease incidence and lesion

Studies on thiabendazole resistance of Penicillium expansum of pears: pathogenic fitness and genetic characterization Tập 52 Số 3 - Trang 362-370 - 2003
Elena Baraldi, Marta Mari, Elena Chierici, M. Pondrelli, P. Bertolini, G.C. Pratella
Isolates of Penicillium expansum recovered from stored pears were scored for
resistance to the fungicide thiabendazole (TBZ) and for pathogenic fitness. Out
of 50 isolates, nine were sensitive (S) and 41 resistant (R or RR). Seven of
these resistant isolates (RR) germinated with a higher percentage on TBZ‐amended
medium than on unamended medium. Six S isolates and six RR isolates were chosen
at ra... hiện toàn bộ
Phylogenetic relationships and pathogenicity of Colletotrichum acutatum isolates from grape in subtropical Australia Tập 56 Số 3 - Trang 448-463 - 2007
Melanie A. Whitelaw-Weckert, Shaun J. Curtin, Rong Huang, Christopher Steel, Christopher Blanchard, Paul Roffey
The identity of Colletotrichum acutatum as the causal pathogen of grape
ripe‐rot, which causes yield loss and a bitter taint that lowers wine quality in
Australian subtropical wine‐grape regions, was confirmed using species‐specific
primers. Cultural, morphological and molecular methods (RAPD‐PCR and sequencing
of parts of the 5·8S‐ITS regions and the β‐tubulin‐2 gene) were used to
determine the p... hiện toàn bộ
Inheritance of resistance to carboxylic acid amide (CAA) fungicides in Plasmopara viticola Tập 56 Số 2 - Trang 199-208 - 2007
U. Gisi, Maya Waldner, N. Kraus, Pierre-Henri Dubuis, Helge Sierotzki
Mandipropamid is a new mandelic acid amide fungicide expressing high activity
against foliar infecting oomycetes, including the grapevine downy mildew,
Plasmopara viticola. Because cross‐resistance with the valinamide fungicides
iprovalicarb and benthiavalicarb and the cinnamic acid amide fungicides
dimethomorph and flumorph was postulated, all five compounds are classified as
carboxylic acid amid... hiện toàn bộ
