Development of a quantum dots FRET-based biosensor for efficient detection of Polymyxa betae

Rhizomania is the most destructive disease in sugar beet throughout the world. The disease is caused by Beet necrotic yellow vein virus (BNYVV). Polymyxa betae (Keskin) is the only known vector of BNYVV, for transmission of the virus between the plants. Developing molecular diagnostic methods has a major impact on forecasting and epidemiological . . . → Read More: Development of a quantum dots FRET-based biosensor for efficient detection of Polymyxa betae

FungiQuant: A broad-coverage fungal quantitative real-time PCR assay

Background Fungal load quantification is a critical component of fungal community analyses. Limitation of current approaches for quantifying the fungal component in the human microbiome suggests the need for new broad-coverage techniques. Methods We analyzed 2,085 18S rRNA gene sequences from the SILVA database for assay design. We generated and quantified plasmid . . . → Read More: FungiQuant: A broad-coverage fungal quantitative real-time PCR assay

Early detection of gray mold in grape using conventional and molecular methods

Botrytis cinerea affects grape quality and yield, and can be difficult to manage due in part to non-symptomatic, quiescent infection in berry development. The aim of this study was to develop a dual system for the detection, isolation and quantification of B. cinerea. After three days of samples replication on the modified selective . . . → Read More: Early detection of gray mold in grape using conventional and molecular methods

The principle of LAMP method

[ Eiken GENOME SITE ] – The principle of LAMP method.

“LAMP” which stands for Loop-mediated Isothermal Amplification is a simple, rapid, specific and cost-effective nucleic acid amplification method solely developed by Eiken Chemical Co., Ltd. It is characterized by the use of 4 different primers specifically designed to recognize 6 distinct regions on . . . → Read More: The principle of LAMP method

ATP citrate lyase 1 (acl1) gene-based loop-mediated amplification assay for the detection of the Fusarium tricinctum species complex in pure cultures and in cereal samples

The combined data set of the acl1 and tef-1α gene sequences of 61 fungal strains assigned to Fusarium tricinctum, Fusarium avenaceum, Fusarium acuminatum, Fusarium arthrosporioides, Fusarium flocciferum and Fusarium torulosum were used to study the phylogenetic relations between taxa. F. tricinctum, F. acuminatum and F. avenaceum formed distinct clades. Members of the F. . . . → Read More: ATP citrate lyase 1 (acl1) gene-based loop-mediated amplification assay for the detection of the Fusarium tricinctum species complex in pure cultures and in cereal samples
