Mungbean (Vigna radiata L.) is routinely grown in the experimental fields at headquarters of World Vegetable Center (23°6'30.88N, 120°17'51.31E) for breeding, research and germplasm multiplication. In a spring 2016 mungbean trial, about 50% plants were affected with powdery mildew. The white, powdery-like patches first appeared on upper leaf surfaces, soon developed to grey both sides leaves. P...

Önemli ekolojik, ekonomik ve sağlık sorunlarına neden olan yabancı otların sürdürülebilir bir yönetimi için biyolojik mücadele çalışmalar giderek daha fazla ilgi görmektedir. Hedef ot türleri üzerindeki potansiyel kontrol ajanlarının (zararlılar, patojenler vb.) tespiti mücadelenin ilk adımıdır türün biyokontrolü temel bilgiler sağlar. Bu çalışmada Hakkari/Yüksekova havzasında zararlı otlar üze...

To study the phylogenetic relationships between Erysiphe s. lat. and Microsphaera, the nucleotide sequences of internal transcribed spacers ofrDNA including 5.8S rDNA gene were determined for 23 taxa. The results showed that Erysiphe. section Erysiphe and Microsphaera are closely related and clustered together with strong bootstrap support (100%). All oftaxa belonging to this group produce coni...

BACKGROUND The study was aimed to evaluate the anti-inflammatory activity of ethanolic and aqueous extracts of Polygonum minus (Huds) using in vitro and in vivo approaches. METHODS The in vitro tests used to evaluate ethanolic extract are cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), lipooxygenase (5-LOX), secretory phospholipase-A2 (sPLA2) inhibition assay whilst the in-vivo effect was...

Raw and processed Radix Polygoni Multiflori have been used in the prevention and treatment of nonalcoholic fatty liver disease (NAFLD), hyperlipidemia, and related diseases in Asian counties for centuries. The lipid regulation ability of raw and processed Poligoni Multiflori Radix were compared in high-fat diet fed rats in this research. Total cholesterol (TC) and low density lipoprotein-choles...

Aqueous and ethanol extracts of different traditional Malaysian plants (Polygonum minus, Andrographis paniculata, Curcuma xanthorrhiza, Momordica charantia and Strobilanthes crispus) were evaluated for their antioxidant properties, total phenolic content and cytotoxic activity. Antioxidant activity was evaluated by using 1,1-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power...
