“…Some diseases are sap-transmissible but have different particle morphology: groundnut eyespot (DUBERN andDOLLET 1978, 1980), groundnut rosette (OKUSANYA and WATSON 1966), peanut clump (THOUVENEL et aL 1976), tomato spotted wnlt (HELMS 1961), tobacco mosaic (NIAZI 1973), okra mosaic (GIVORD and HIRTH 1973), passionfruit woodiness (TAYLOR and GRABER 1973), and clitoria yellow vein (BOCK and GUTHRIE 1977). Moreover, some sap-transmissible viruses have unknown particle morphology: groundnut chlorotic spot (HARAGOPAL and NAYUDU 1971), groundnut ringspot (KLESSER 1966), groundnut veinbanding (KLESSER 1967) and groundnut chlorosis (SHARMA 1966); all these diseases are different in their symptomatology, host range and in vitro properties, and are insect transmissible.…”

A virus causing wide chlorotic ringspot (PCRV) associated with chlorotic line pattern and motthng on an Erictoides hybrid growing in USDA‐OSU greenhouses, Stillwater, Oklahoma, was discovered. The virus was isolated and characterized and found to differ in symptomology, host range and serological properties from all the previously described viruses infecting peanut, particularly those reported in the United States to be the most important ones, peanut mottle virus, peanut stripe virus, and tomato spotted wilt virus. The virus was transmitted by both mechanical inoctilation and grafting to fourteen peanut cultivars causing identical symptoms to those originally observed on the Erictoides hybrid. In addition to peanut, the virus systemically infected Pisum sativum L. ‘Little marvel’ causing mainly mosaic and Lupinus albus L. ‘Tiftwhite’ producing severe malformation and remarkable reduction in leaflet area. The virus did not infect many other plant species of which cowpea ‘California blackeye’ (Vigna unguiculata L.) and at least five cultivars of soybean (Glydne max L.) are known to be susceptible hosts to peanut mottle virus. Phaseolus vulgaris L. ‘Topcrop’ and Chenopodium amaranticohr Coste & Reyn were found to be two useful local lesion assay and diagnostic hosts for PCRV. The virus elicited necrotic local lesions on the first and chlorotic ringspots on the second. PCRV had a dilution end point between 10−5 and 10−6, thermal inactivation point between 55°C and 60°C, and longevity in vitro up to 6 days but not 7 days. Virus particles viewed hy electron microscopy and the negative stain uranyl aceute were flexuous filamentous particles ranging in length from 750–850 nm. In both indiren PAS‐ELISA and Ouchterlony double immunodiffusion test, PCRV was serologically related to a PMV isolate from Oklahoma (PMV‐OK.) but not to bean yellow mosaic virus, peanut stripe virus, potato virus Y, watermelon mosaic virus 1, watermelon mosaic virus 2, wheat streak mosaic virus, and zucchini yellow mosaic virus.
