A multiplex nested PCR assay was developed by optimizing reaction components and reaction cycling parameters for simultaneous detection of Corchorus golden mosaic virus (CoGMV) and a phytoplasma (Group 16Sr V-C) causing little leaf and bunchy top in white jute (Corchorus capsularis). Three sets of specific primers viz. a CoGMV specific (DNA-A region) primer, a 16S rDNA universal primer pair P1/P7 and nested primer pair R16F2n/R2 for phytoplasmas were used. The concentrations of the PCR components such as primers, MgCl2 , Taq DNA polymerase, dNTPs and PCR conditions including annealing temperature and amplification cycles were examined and optimized. Expected fragments of 1 kb (CoGMV), 674 bp (phytoplasma) and 370 bp (nested R16F2n/R2) were successfully amplified by this multiplex nested PCR system ensuring simultaneous, sensitive and specific detection of the phytoplasma and the virus. The multiplex nested PCR provides a sensitive, rapid and low-cost method for simultaneous detection of jute little leaf phytoplasma and CoGMV. Based on BLASTn analyses, the phytoplasma was found to belong to the Group 16Sr V-C.
