Detection of Cymbidium mosaic virus and Odontoglossum ringspot virus in Phalaenopsis in Korea

Reciprocal function of movement proteins and complementation of long-distance movement of Cymbidium mosaic virus RNA by Odontoglossum ringspot virus coat protein.

Complementation of movement and coat proteins of the orchid-infecting potexvirus Cymbidium mosaic virus (CymMV) and tobamovirus Odontoglossum ringspot virus (ORSV) was investigated. Nicotiana benthamiana, which is susceptible to both CymMV and ORSV, was used as a model system. Four transgenic lines, each harbouring one of the movement protein (MP) or coat protein (CP) genes of CymMV or ORSV, we...

Detection of Cymbidium Mosaic Virus (CYMV) on Vanda Plants

Orchid plants are the members of Orchidaceae consisting of more than 25,000 species, which are distributed almost all over the world but more abundantly in the tropics. There are 177 genera, 1,125 species of orchids that originated in Thailand. Orchid plant collected from different nurseries showing Chlorotic and mosaic symptoms were observed on Vanda plants and it was suspected to infect with ...

Study of resistance to cucumber mosaic virus watermelon mosaic virus and zucchini yellow mosaic virus in melon cultivars

De novo generation of cymbidium ringspot virus defective interfering RNA.

Nicotiana clevelandii plants were inoculated with cymbidium ringspot tombusvirus RNA synthesized in vitro, after which further passages were made by sap inoculation. During the third passage, low Mr RNA species appeared which had the characteristics of deletion mutants of genomic RNA. Sequence analysis of several of these defective interfering RNAs suggested a possible evolution of smaller from...
