First report of Fusarium chlamydosporum causing crown rot and dumping of on Durum wheat in Algeria
Several species of Fusarium infect durum wheat plants in the eastern part of Algeria. Endophytic fungus from random wheat seeds were sampled from fifty locations in eastern Algeria and shows the existence of Fusarium chlamydosporum regarding the macroscopic and microscopic characteristics. Molecular identification using EF1 and ITS1 primers were confirmed the presence of Fusarium chlamydosporum...
متن کاملMolecular Characterization of Rhizoctonia Solani Ag-7 Causing Root Rot on Cotton Crop in India
Rhizoctonia solani (Kuhn) is one of the most important cotton crop pathogens. Rhizoctonia solani anastomosis groups (AGs) 7 and 4 are proven to be the most common pathogenic fungal strains on cotton crop. AG-7 can cause root rot in plants while damping-off of seedlings is most frequently attributed to AG-4. Sequencing of the ITS (Internal Transcribed Spacer) region of ribosomal DNA was performe...
متن کاملDefense-related genes expressed in Norway spruce roots after infection with the root rot pathogen Ceratobasidium bicorne (anamorph: Rhizoctonia sp.).
To study the mechanisms of inducible disease resistance in conifers, changes in transcript accumulation in roots of Norway spruce (Picea abies (L.) Karst.) seedlings exposed to the root rot pathogen Ceratobasidium bicorne Erikss. and Ryv. (anamorph: Rhizoctonia sp.) were monitored by differential display (DD). Because C. bicorne attacks root tips, a desiccation treatment was added to exclude ge...
متن کاملIdentification and characterization of a novel Iraqi isolate of Fusarium pseudograminearum causing crown rot in wheat.
Crown rot is one of the main important fungal diseases affecting wheat in many areas of the world, including Australia, USA, and Iran. Until now, there had been no report of this pathogen in Iraq. Plants displaying crown rot symptoms were observed in Shaat Alarab (Basra, Iraq); we investigated the causal agent of the disease. Samples were surface-sterilized in bleach (1% available chlorine...
متن کاملFirst Report of Myrothecium roridum Causing Leaf and Stem Rot Disease on Peperomia quadrangularis in Korea
In 2010, symptoms of leaf and stem rot were observed on potted plants (Peperomia quadrangularis) in a greenhouse in Yongin, Korea. The causative pathogen was identified as Myrothecium roridum based on morphological data, internal transcribed spacer sequence analysis, and pathogenicity test. To our knowledge, this is the first report of M. roridum causing leaf and stem rot disease on P. quadrang...
