Tiga fungisida serap yang baru iaitu Aliette (efosite-Al), Ridomil (metalaxyl) serta Ridomil MZ (metalaxyl dengan mancozeb) dan dua fungisida biasa Terrazole (etridiazole) serta Difolatan (captafol) telah diuji kesan profilaktik dan terapeutik ke atas Phytophthora palmivora pada orkid. Pucuk-pucuk punca haibrid Aranda Christine dapat dikawal dengan berkesan daripada jangkitan Phytophthora apabi...
Phytophthora effector targets a novel component of small RNA pathway in plants to promote infection.
A broad range of parasites rely on the functions of effector proteins to subvert host immune response and facilitate disease development. The notorious Phytophthora pathogens evolved effectors with RNA silencing suppression activity to promote infection in plant hosts. Here we report that the Phytophthora Suppressor of RNA Silencing 1 (PSR1) can bind to an evolutionarily conserved nuclear prote...
The oomycete plant pathogen, , is Background: Phytophthora cinnamomi responsible for the destruction of thousands of species of native Australian plants, as well as several crops, such as avocado and macadamia, and has one of the widest host-plant ranges of the genus. The current Phytophthora reference genome of is based on an atypical strain and has large P. cinnamomi gaps in its assembly. To ...

Surveys of Australian and South African rivers revealed numerous Phytophthora isolates residing in clade 6 of the genus, with internal transcribed spacer (ITS) gene regions that were either highly polymorphic or unsequenceable. These isolates were suspected to be hybrids. Three nuclear loci, the ITS region, two single copy loci (antisilencing factor (ASF) and G protein alpha subunit (GPA)), and...
Plants protect themselves against a variety of invading pathogenic organisms via sophisticated defence mechanisms. These responses include deployment of specialized antimicrobial compounds, such as phytoalexins, that rapidly accumulate at pathogen infection sites. However, the extent to which these compounds contribute to species-level resistance and their spectrum of action remain poorly under...
A family of sequences resembling Gypsy retroelements was identified and shown to be widely distributed throughout the genus Phytophthora, a member of the algallike oomycete fungi. Polymerase chain reaction (PCR) using specific and degenerate primers detected the family in 29 of 37 species tested. DNA hybridization also failed to detect the sequences in the eight species that were negative in PC...
Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...
shenavar o. & mostowfizadeh-ghalamfarsa r. 2015. computerized interactive keys for identification of fungi. plant pathology science 4(2):41-52 accurate identification of fungi and fungus-like organisms is one of the most important steps for finding an approach to employ or control them. nevertheless, this process is usually laborious and slow. application of interactive keys is one of the way...
