AFLP analysis of a worldwide collection of Didymella bryoniae.
Didymella bryoniae (anamorph Phoma cucurbitacearum) is an ascomycete that causes gummy stem blight, a foliar disease that occurs on cucurbits in greenhouses and fields throughout the world. In a previous study using RAPD analysis, little genetic diversity was found among isolates of D. bryoniae from New York and South Carolina, USA. Here we report the use of amplified fragment length polymorphi...
متن کاملRapid and Sensitive Detection of Didymella bryoniae by Visual Loop-Mediated Isothermal Amplification Assay
Didymella bryoniae is a pathogenic fungus that causes gummy stem blight (GSB) in Cucurbitaceae crops (e.g., cantaloupe, muskmelon, cucumber, and watermelon). GSB produces lesions on the stems and leaves, and can also be spread by seeds. Here, we developed a rapid, visual, and sensitive loop-mediated amplification (LAMP) assay for D. bryoniae detection based on sequence-characterized amplified r...

متن کاملFusion de multi-modalités et réduction par sémantique latente
This paper studies Latent Semantic Analysis (LSA) between visual and textual elements of a multimedia collection, applied on two different tasks: (1) multimedia document retrieval (MDR) and (2) automatic image annotation (AIA). Latent semantics, usually used for text indexing, is applied to discover hidden semantic relations between visual and textual descriptors. The contributions of this pape...
متن کاملCryptosporidium infections in birds - a review Infecção por Cryptosporidium em aves - uma revisão Alex
Cryptosporidiosis is one of the main protozoan infections in birds. It manifests as either a respiratory or a digestive illness, and it affects a very large number of avian species across several continents. The aim of this review is to report on the main results of studies on cryptosporidiosis among birds and the importance of these results to veterinary medicine and public health.
