“…Virus purification was from A.porrum ('Goliath') as described for LYSV (Huttinga, 1975) and for OYDV (Bos et al, 1978) using molecular sieving on Sephadex G-200 and extended by equilibrium density-gradient centrifuging in CsC1 when for antiserum production. Biophysical properties were also determined as for OYDV.…”

“…It is widely known as an important host of onion yellow dwarf virus (OYDV, Bos, 1976). Soon after initiation of studies on leek yellow stripe virus (LYSV) in leek (A. porrum) and its relationships to OYDV (Bos et al, 1978) a symptomless virus was detected in shallot. It occurred in high concentrations, was more rigid in particle form than OYDV and obviously belonged to the carlavirus group (Bos, 1972).…”

A new carlavirus, apparently omnipresent in shallot (Allium ascalonicum) without causing symptoms, is described as shallot latent virus. It has also been detected in naturally infected onion (A. cepa) Dilution end-point was 104-10s, thermal inactivation at ca. 80~ and ageing in vitro 8 11 days. Purification by molecular sieving on Sephadex G-200 followed by equilibrium density-gradient centrifuging in CsCI was successful. Sedimentation coefficient was 147.5 S, buoyant density 1.313 g/cm 3 and molecular mass of protein snbunits 23 200 dalton. With the antiserum (titre 1024) distant serological relationships to some carlaviruses were determined. No inclusion bodies were observed with the light microscope. With the electron microscope a high concentration of straight or slightly curved particles with a normal length of 650 to 652 nm could easily be detected in crude sap and in purified preparations.

“…On the basis of the symptoms on leeks, particle morphology, host range, and serology, it is concluded that the leek virus described here is an isolate of leek yellow stripe, a virus which has been described in Europe by Bos et al (1978). LYSV is an apparently distinct virus widespread in leek crops in Europe, causing losses of economic importance (Bos et al 1978).…”

“…LYSV is an apparently distinct virus widespread in leek crops in Europe, causing losses of economic importance (Bos et al 1978). In New Zealand, however, the disease has been recorded on only one farm in Hastings where, in two consecutive years, an incidence of 100%was reported.…”

“…The virus is not known to be seed transmitted and the only likely sources of infection for a young crop are infected overwintering leek crops (Bos et al 1978). Initial spread of disease into a new crop occurs in spring and spread within the crop takes place in late summer-early autumn; by winter, a disease incidence of 100% is common in most crops (Bos et al 1978). These authors recommend a leekfree period and/or isolation of seed beds combined with roguing of infected plants in spring or early summer to control the disease.…”

Leek (Allium porrum L.) plants showing a distinct yellow streaking of the leaves were found to be infected with a flexuous, rod-shaped virus, approximately 700 nm long. On the basis of symptoms, host range, particle morphology, and serology, this virus was indentified as leek yellow stripe virus. In New Zealand, this disease has been reported from only one property in the Hastings area where an incidence of nearly 100% was recorded in 1978 and 1979.
