Two novel Pseudomonas strains (S1E40 and S3E12) isolated from corn roots are antagonistic to Rhizoctonia solani and exhibit differential hypersensitivity reactions on tobacco and corn seedlings. We report here the draft genome sequences of strains S1E40 and S3E12, consisting of 6.98 and 7.06 Mb with 6,150 and 6,129 predicted protein-coding sequences, respectively.
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...
To identify Nicotiana tabacum genes involved in resistance and susceptibility to the phytopathogenic fungus Rhizoctonia solani, transcripts were generated (by subtractive libraries), which were differentially expressed in each interaction. This enabled isolation of a gene coding for a protein kinase that becomes silent during the susceptibility interaction and is activated during resistance. Th...
به منظور شناسایی عوامل بیماریهای رایزوکتونیایی گندمیان و میزبانهای جدید این بیماریها، در طول بیش از یک سال از مزارع غلات ، باغات و مراتع شهرستانهای مرکزی استان مازندران، نمونه برداری گردید. پس از کشت و جداسازی، 86 جدایه به دست آمد که از این تعداد، 77 جدایه به رایزوکتونیاهای چند هسته ای و 9 جدایه به دو هسته ایها تعلق داشت . از بین جدایه های چند هسته ای، 59 جدایه به گروه آناستوموزی ag1 از rhizoct...
Expression of the linear DNA plasmid-encoded protein (RS224) from the plant-pathogenic fungus Rhizoctonia solani isolate H-16, anastomosis group 2-2, and its localization were studied. Extracts from Escherichia coli cells expressing the open reading frame (ORF) of RS224 (RS224ORF in pRS224) contain a 92-kDa T7.Tag-RS224orf fusion protein. Antisera raised against the fusion protein obtained from...
A study was undertaken to explore the effect of volatile oils from Eucalyptus citriodora and its major constituent citronellal against two well-known rice pathogens, Rhizoctonia solani and Helminthosporium oryzae. The radial growth and dry weight of both the test fungi were drastically reduced in response to the volatile oils. A complete inhibition of R. solani and H. oryzae was observed at 10 ...
Bioassay-guided separation with an eye toward antifungal activity led to the isolation of the new alkaloid 5-(1̀,1̀-dimethylallyl)-8-hydroxyfuro[2-3-b] quinoline (1) and the known biscoumarin daphnoretin (2) as the active constituents of the chloroform extract obtained from the leaves of Ruta chalepensis. The structures of the metabolites were elucidated on the basis of their spectral characteris...
Rhizoctonia solani is a soil-borne fungus causing sheath blight. In consistent with its necrotrophic life style, no rice cultivars fully resistant to R. solani are known, and agrochemical plant defense activators used for rice blast, which upregulate a phytohormonal salicylic acid (SA)-dependent pathway, are ineffective towards this pathogen. As a result of the unavailability of genetics, the i...
From the seeds of Acacia confusa, a chitinase-like antifungal protein designated as acaconin that demonstrated antifungal activity toward Rhizoctonia solani with an IC₅₀ of 30±4 µM was isolated. Acaconin demonstrated an N-terminal sequence with pronounced similarity to chitinases and a molecular mass of 32 kDa. It was isolated by chromatography on Q-Sepharose, SP-Sepharose and Superdex 75 and w...
