Calla lilies are ornamental plants of major economic importance in Taiwan. They are grown in the central and northern areas of the island, and ≈3 million stems are shipped annually. Calla lilies are susceptible to several viruses (1). Infections by Cucumber mosaic virus, Dasheen mosaic virus, Turnip
Through sequencing and assembly of small RNAs, an orthotospovirus was identified from a celtuce plant (Lactuca sativa var. augustana) showing vein clearing and chlorotic spots in the Zhejiang province of China. The S, M, and L RNAs of this orthotospovirus were determined to be 3146, 4734, and 8934
This study investigated the long term use of Eclipse, a cigarette-like device that heats rather than burns tobacco, and the Nicorette oral inhaler, a nicotine replacement product, in a group of smokers not interested in quitting smoking. Subjects were recruited from a previous four-week controlled
In July 2000, concentric necrotic rings and patterns were observed on greenhouse-grown pepper (Capsicum anuum L. 'Blondi'). Symptoms were present only on lower leaves, not on young leaves or fruits. Typical tospovirus particles using electron microscopy were observed in leaf-dip preparations of
Lisianthus necrosis virus (LNV) was first identified as a fungus-borne virus that induced systemic necrosis in lisianthus (Eustoma russellianum) in Japan (2). In Taiwan, LNV causes systemic bright yellow chlorosis followed by necrosis in lisianthus (1). The disease was able to spread through the
BACKGROUND
Emerging tospoviruses cause significant yield losses and quality reduction in vegetables, ornamentals, and legumes throughout the world. So far, eight tospoviruses were reported in China. Tomato fruits displaying necrotic and concentric ringspot symptoms were found in Guizhou province of
In February 2004, leaf yellowing, mottling, and mosaics were observed on a few plants of a Zantedeschia sp. (calla lily) growing in Rangiora, Canterbury, New Zealand. Zantedeschia spp. are known to be susceptible to at least 13 virus species (1). No symptoms were observed on Chenopodium
