The nucleotide sequence of the 3'-terminal region of the Korean isolate of cymbidium mosaic virus (CyMV-Ca) from a naturally infected cattleya was determined. The sequence contains an open reading frame (ORF) coding for the viral coat protein (CP) at the 3'-end and three other ORFs (triple gene

Cymbidium mosaic virus (CyMV) is the most prevalent virus infecting orchids. Here, we report the isolation of partial cDNA clones encoding the genomic RNA of CyMV. Like most of the polyadenylated monopartite positive-strand RNA viruses, the open reading frame (ORF) coding for the viral coat protein

Transgenic Nicotiana benthamiana plants expressing the coat protein gene of cymbidium ringspot virus (CyRSV) were tested for resistance against infection with CyRSV. Transgenic plants showed resistance to infection only when the purified virions concentration in the inoculum was as low as 0.05

In plants, posttranscriptional gene silencing (PTGS) is an ancient and effective defense mechanism against viral infection. A number of viruses encode proteins that suppress virus-activated PTGS. The p19 protein of tombusviruses is a potent PTGS suppressor which interferes with the onset of
Functional analysis of FLOWERING LOCUS T orthologs from spring orchid (Cymbidium goeringii Rchb. f.) that regulates the vegetative to reproductive transition.

The FLOWERING LOCUS T (FT) gene plays crucial roles in regulating the vegetative-to-reproductive phase transition. The FT-like gene of spring orchid (Cymbidium goeringii Rchb. f.), CgFT, was isolated and characterized. CgFT mRNA was detected in leaves, pseudobulb, and flowers. In flowers, CgFT was
Involvement of CsERF2 in leaf variegation of Cymbidium sinense 'Dharma'

CsERF2, an ethylene response factor, plays a role in leaf variegation. Leaf variegation is a main ornamental characteristic in Cymbidium sinense (C. sinense). However, the mechanisms of leaf color variegation remain largely unclear. In the present study, we analyzed the cytological and physiological

In 2010, a survey for viral diseases in commercial, orchid-producing greenhouses was carried out in Morelos, Mexico. Many symptomatic plants were observed. The most common leaf symptoms were yellow mottle, yellow streaks, and chlorotic and necrotic ringspots. Leaf samples were collected from eight

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

The spread of cymbidium ringspot tombusvirus (CyRSV) in host tissue was studied by using a coat protein gene mutant with a six-nucleotide deletion; the deletion removes two amino acids from the shell domain (S) of the capsid protein. Mutated protein subunits were synthesized in infected cells but

Ultrastructural studies of Nicotiana clevelandii plants systemically infected with Cymbidium ringspot virus, a member of the tombusvirus group, have shown that a clear-cut relationship exists between perioxisomes and multivesicular bodies (MVB). In infected cells, peroxisomes undergo a progressive

A full-length DNA copy of cymbidium ringspot virus (CyRSV) satellite RNA was cloned downstream of the bacteriophage T7 RNA polymerase promoter. In vitro transcripts were biologically active in plants when coinoculated with the helper virus or its RNA. Although the transcripts contained 7 or 29 extra
