In September 2008, Narcissus plants originating from commercial nurseries in Taranaki (TK) in New Zealand's North Island and Canterbury (CB) in the South Island were received showing leaf mottling, flower distortion, and color break. The CB plant also showed stunting. Filamentous virus particles
A potyvirus from Chinese narcissus was transmitted mechanically to three species of Narcissus and to Lycoris radiata but not to 22 other test species. In western blot, the coat protein reacted strongly with Narcissus degeneration virus (UK isolate) antiserum. Antiserum raised to the Chinese virus
Potyvirus species associated with yellow leaf stripe disease of Indian narcissus (Narcissus tazetta L.) var. Paperwhite has been studied by sequence analyses of ~ 1.5 kb genomic fragments obtained from seven RT-PCR amplifications of infected samples. Sequence analysis revealed the occurrence
Self-pollination results in significantly lower seed set than cross-pollination in tristylous Narcissus triandrus. We investigated structural and functional aspects of pollen-pistil interactions and ovule-seed development following cross- and self-pollination to assess the timing and mechanism of
There is no attempt to evaluate evolutionary rates, timescales and diversities of viruses collected from mixedly infected hosts in nature. Plants of the genus Narcissus are a monocotyledon and are susceptible to several viruses. In this study, narcissus plants (Narcissus tazetta var. chinensis)
BACKGROUND
Daffodils (Narcissus pseudonarcissus) are one of the world's most popular ornamentals. They also provide a scientific model for studying the carotenoid pigments responsible for their yellow and orange flower colours. In reverse bicolour daffodils, the yellow flower trumpet fades to white
Complete genome sequences were obtained from two isolates of the carlavirus nerine latent virus from hippeastrum and narcissus plants, two isolates of the potyvirus hippeastrum mosaic virus from a hippeastrum plant, and one isolate each of the potyviruses narcissus degeneration virus, narcissus
