Several species of the genus Dickeya provoke soft rot and blackleg diseases on a wide range of plants and crops. Dickeya solani has been identified as the causative agent of diseases outbreaks on potato culture in Europe for the last decade. Here, we report the complete genome of the D. solani IPO 2222T. Using PacBio and Illumina technologies, a unique circular chromosome of 4,919,833 bp was as...
Experiments were established in field microplots to examine the association between Heterodera glycines and the blue form of Fusarium solani in sudden death syndrome of soybean (SDS). Foliar disease symptoms occurred on more plants per plot, appeared 3 to 7 days earlier, and were more severe on plants grown in plots infested with F. solani + H. glycines than on those inoculated with F. solani o...
Soreshin of cotton was more severe from combined infections of Rhizoctonia solani and Meloidogyne incognita than from either organism alone, when both critical soil temperature and inoculum concentrations were present. Optimum soil temperatures for disease development from combined infections were 18 and 21 C. Either 2,500 or 5,000 M. incognita larvae per plant, combined with R. solani, increas...
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...
Rhizoctonia solani is a nectrotrophic fungal pathogen that causes billions of dollars of damage to agriculture worldwide and infects a broad host range including wheat, rice, potato and legumes. In this study we identify wheat genes that are differentially expressed in response to the R. solani isolate, AG8, using microarray technology. A significant number of wheat genes identified in this scr...
Biotic stress, as a result of plant-pathogen interactions, induces the accumulation of reactive oxygen species in the cells, causing severe oxidative damage to plants and pathogens. To overcome this damage, both the host and pathogen have developed antioxidant systems to quench excess ROS and keep ROS production and scavenging systems under control. Data on ROS-scavenging systems in the necrotr...
Fusariosis is an emerging opportunistic mycosis against which currently used antifungals have limited activity. Here, we investigated the in vitro activities of pentamidine (PNT) against 10 clinical isolates of Fusarium species (five Fusarium solani isolates and five non-F. solani isolates) by using the National Committee for Clinical Laboratory Standards microdilution method in three different...
PURPOSE To investigate the predominant causative pathogens and epidemiologic features of fungal keratitis and establish a rapid, specific molecular method to detect fungal keratitis caused by Fusarium solani. METHODS A total of 174 patients with presumed fungal keratitis and 174 affected eyes were examined. Isolates from corneal specimens were identified according to morphologic and physiolog...
Garlic leaf blight caused by Stemphylium solani is a serious disease in vegetable-growing areas of China (28). Symptoms of the disease start as small white spots (1 to 3 mm) enlarging to elongated purple necrotic lesions along the vein, followed by blighting of the leaf tips. Similar symptoms were produced by culture filtrates of S. solani, and a strong correlation was also found between garlic...
To explore the pathogenesis of Rhizoctonia solani and its phytotoxin phenylacetic acid (PAA) on maize leaves and sheaths, treated leaf and sheath tissues were analyzed and interpreted by ultra-performance liquid chromatography-mass spectrometry combined with chemometrics. The PAA treatment had similar effects to those of R. solani on maize leaves regarding the metabolism of traumatin, phytosphi...
