Helleborus net necrosis virus (HeNNV) in hellebores (Helleborus spp.) has been detected for the first time in Japan. Infected plants had black streaks on fresh leaves and black spots on sepals, which resembled the symptoms of black death disease. The morphology of the virus particles isolated from infected plants was comparable to that of carlaviruses. RT-PCR analysis showed that the entire HeNNV genomic sequence isolated in Japan shared 99% identity with that of HeNNV previously reported in… Expand

Figures and Tables from this paper

N-terminal region of cysteine-rich protein (CRP) in carlaviruses is involved in the determination of symptom types.
TLDR
Although all six tested carlavirus CRPs showed RNA silencing suppressor activity at similar levels, symptoms induced by the Potato virus X (PVX) heterogeneous system exhibited two different patterns: leaf malformation and whole-plant stunting, suggesting that both motifs play critical roles in symptom expression.

Helleborus net necrosis virus: A New Carlavirus Associated with 'Black Death' of Helleborus spp.
TLDR
Particle size, dsRNA patterns, genome organization, and sequence were consistent with members of the family Flexiviridae, genus Carlavirus, and the name Helleborus net necrosis virus (HeNNV) is proposed for the virus associated with black death of Hellebore spp. Expand

TLDR
The findings suggest that this species is an emerging host for PSTVd and that dissemination of seed may provide a pathway for international movement of the viroid. Expand

TLDR
Britain as an island has a flora and fauna that is relatively impoverished compared with mainland Europe but nevertheless has a wide diversity of plants and animals, most of which are of value from both biodiversity and social perspectives. Expand
