Survey and RT-PCR Based Detection of Cardamom mosaic virus Affecting Small Cardamom in India

Cardamom, Ginger and Turmeric

Optimized expression, solubilization and purification of nuclear inclusion protein b of cardamom mosaic virus.

All RNA viruses encode an RNA-dependent RNA polymerase (RdRP) that is required for replication of the viral genome. Nuclear inclusion b (NIb) gene codes for the RdRp in Potyviridae viruses. In this study, expression, solubilization and purification of NIb protein of Cardamom mosaic virus (CdMV) is reported. The objective of the present study was to express and purify the NIb protein of CdMV on ...

Transcriptome profiling of Elettaria cardamomum (L.) Maton (small cardamom)

Elettaria cardamomum (L.) Maton, known as 'queen of spices, is a perennial herbaceous monocot of the family Zingiberaceae, native to southern India. Cardamom is an economically valuable spice crop and used widely in culinary and medicinal purposes. In the present study, using Ion Proton RNA sequencing technology, we performed transcriptome sequencing and de novo transcriptome assembly of a wild...

Detection of Tobacco mosaic virus and Tomato mosaic virus in pepper and tomato by multiplex RT-PCR.

AIMS To develop a highly sensitive and rapid protocol for simultaneous detection and differentiation of Tobacco mosaic virus (TMV) and Tomato mosaic virus (ToMV) in pepper and tomato. In this study, we use the multiplex PCR technique to detect dual infection of these two viruses. METHODS AND RESULTS A multiplex RT-PCR method consisting of one-tube reaction with two primer pairs targeted to re...

Molecular modeling and conformational analysis of native and refolded viral genome-linked protein of cardamom mosaic virus.

The viral genome-linked protein (VPg) of Potyviruses is covalently attached to the 5' end of the genomic RNA. Towards biophysical characterization, the VPg coding region of Cardamom mosaic virus (CdMV) was amplified from the cDNA and expressed in E. coli. Most of the expressed VPg aggregated as inclusion bodies that were solubilized with urea and refolded with L-arginine hydrochloride. The vari...
