Dahlia Mosaic Virus: Molecular Detection and Distribution in Dahlia in the United States

Seed Transmission of Dahlia mosaic virus in Dahlia pinnata

The Dahlia mosaic virus gene VI product N-terminal region is involved in self-association.

The genome of the floriculture pathogen Dahlia mosaic caulimovirus (DMV) encodes six open reading frames. Generally, caulimovirus gene VI products (P6s) are thought to be multifunctional proteins required for viral infection and it is likely that self-association is required for some of these functions. In this study, yeast two-hybrid and maltose binding protein (MBP) pull-down assays indicated...

The Dahlia: An Early History

In 1934 Marshall Howe, of the New York Botanical Garden, compiled a list of Dahlia cultivars containing more than 14,000 names. This number represents an astonishing average of over 100 newly named cultivars during each of the 143 years since 1791, when dahlias were first brought into cultivation in the gardens of Spain following their arrival from Mexico. Today dahlias are among the most famil...

A bHLH transcription factor, DvIVS, is involved in regulation of anthocyanin synthesis in dahlia (Dahlia variabilis)

Dahlias (Dahlia variabilis) exhibit a wide range of flower colours because of accumulation of anthocyanin and other flavonoids in their ray florets. Two lateral mutants were used that spontaneously occurred in 'Michael J' (MJW) which has yellow ray florets with orange variegation. MJOr, a bud mutant producing completely orange ray florets, accumulates anthocyanins, flavones, and butein, and MJY...
