Development and application of reverse transcription-loop mediated isothermal amplification assay for sensitive detection of groundnut bud necrosis virus infecting potato.

Reverse-transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for detection of groundnut bud necrosis virus (GBNV) causing potato stem necrosis disease. The isothermal temperatures, reaction periods and concentrations of reaction mixture were optimized where, the assay worked well at 65 °C for 50 min, 6 U of WarmStart Bst 2.0 DNA polymerase, 1.

Economic losses due to infection by apple scar skin viroid in Himachal Pradesh, India.

Apple scar skin viroid (ASSVd), the type member of the genus Apscaviroid, induces symptoms only on fruits, which include colour dappling, russeting, cracking and distortion. Studies on viroid incidence were conducted during past five years and incidence up to 90.0 percent was recorded in commercial apple cultivars (Royal Delicious, Red Delicious, Red Gold, Golden Delicious).

Development and application of fluorescent loop mediated isothermal amplification technique to detect from potato tubers targeting ITS-1 region.

The goal of this study was to develop a fluorescent based loop-mediated isothermal amplification (LAMP) assay for a simple, sensitive and visual detection of from tubers targeting a novel internal transcribed spacer 1 (ITS-1) region of ribosomal DNA. The ITS-1 LAMP primers were designed using the Primer Explorer V4 software. The optimization of LAMP reaction conditions and reagents concentrations were carried out with time, temperature, MgSO, dNTPs and DNA polymerase.

Resistant starch in food: a review.

The nutritional property of starch is related to its rate and extent of digestion and absorption in the small intestine. For nutritional purposes, starch is classified as rapidly available, slowly available and resistant starch (RS). The exact underlying mechanism of relative resistance of starch granules is complicated because those factors are often interconnected.

Molecular Detection of Latent Apple chlorotic leaf spot virus in Elite Mother Plants of Apple.

Apple chlorotic leaf spot virus (ACLSV; family Betaflexiviridae genus Trichovirus) is one of the economically important latent virus infecting apple (Malus × domestica Borkh.). Reverse transcriptase polymerase chain reaction (RT-PCR) procedures were used to amplify coat protein gene of ACLSV.
