Curly Top Virus

Curly Top Virus (CTV) in sugar beet, belonging to the family Geminiviridae, genius Curtovirusis a considerable problem in semiarid areas of the Iran and other semiarid parts of the world. There are several diagnostic methods to detect CTV, But these techniques take a long time for 3 h to tow day, requiring sophisticated tools. The aim of this study, for the first time, was to reduce the time required to detect CTV in sugar beet, using colorimetric loop-mediated isothermal amplification (LAMP) technique requiring only an ordinary water bath or thermoblock.DNA was extracted from infected naturally leaf tissues. Samples were tested for the presence of Curtovirus species by PCR and LAMP reactions to amplify replication-associated protein (rep) gene using species primers. LAMP was optimized to amplify CTV DNA under isothermal conditions by incubation at 63°C for 30 min. LAMP products were detected visually using the different dyes. The LAMP amplification products had a ladder-like appearance when electrophorised on an agarose gel and also positive results using the different dyes were a color change. Results confirmed LAMP with different dyes provides a rapid and safe assay for detection of CTV in sugar beet. OMICS Group International is one of the leading Open Access Publishers which is publishing 700+ peer-reviewed journals with the support of 50,000+ editorial board members as editorial team and aimed to disseminate the scholarly knowledge to the scientific society. OMICS Group also organizing 3000+ International Scientific Conferences and events yearly all over the world with the support of 1000+ Scientific associations worldwide.
