Chrysanthemum chlorotic mottle viroid (CChMVd) is a serious pathogen infecting chrysanthemum worldwide. To improve and enhance the detection procedure, colorimetric loop-mediated isothermal amplifi cation (LAMP) technique was developed. Six LAMP primers were newly designed tested optimal conditions using recombinant plasmid of CChMVd as DNA template. The for incubation at 65°C 60 min. At these ...

The effects of 2 mM silicon (Si) and 10 mM KNO₃ (N)-prime signals for plant resistance to pathogens-were analyzed in healthy and Cowpea chlorotic mottle virus (CCMV) or Cowpea mild mottle virus (CMMV)-infected Bradyrhizobium-nodulated cowpea, yardlong bean and mung bean plants. In healthy plants of the three Vigna taxa, nodulation and growth were promoted in the order of Si + N > N > Si > contr...

UNLABELLED We have recently discovered (R. D. Cadena-Nava et al., J. Virol. 86:3318-3326, 2012, doi:10.1128/JVI.06566-11) that the in vitro packaging of RNA by the capsid protein (CP) of cowpea chlorotic mottle virus is optimal when there is a significant excess of CP, specifically that complete packaging of all of the RNA in solution requires sufficient CP to provide charge matching of the N-t...

The 3' ends of three genomic RNAs (gRNAs) of cowpea chlorotic mottle virus (CCMV) terminate in a highly conserved tRNA-like structure (3'TLS). To examine the intrinsic role played the 3'TLS in packaging, the competence of each gRNA lacking the 3' TLS (DeltaTLS-gRNA) to interact with dissociated coat protein (CP) subunits and form virions was assayed in vitro. In contrast to the well established...

Chrysanthemum plants are one of the most economically important in South Korea. Both virus and viroid can cause diseases economic damage to plants. In this study, we investigated detection seven viruses two viroids 350 chrysanthemum cultivated Yesan-gun, Chungcheongnam-do. Two viruses, B (CVB) tomato aspermy (TAV), viroids, chlorotic mottle (CChMVd) stunt (CSVd), were detected study. The six sa...
