Abstract

Citrus leprosis virus (CiLV) constitutes one of the most important viruses in citrus in the areas where it occurs. Two morphological types of virus particles have been described from associated leprosis symptoms, nuclear (CiLV-N) and cytoplasmic (CiLV-C) (4). The CiLV-C is more common, representing more than 99% of samples collected from South and Central America (E. W. Kitajima and J. C. V. Rodrigues, unpublished). Both virus types are associated with the mite vector, Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae). So far, CiLV-C has only been naturally transmitted by these mites to citrus (3). Plants of Solanum violaefolium Schott (Solanaceae) and ornamental and sweet orange seedlings were infested with viruliferous adult female mites, colony no. 61 (GenBank Accession No. AY320027) that were previously maintained on citrus seedlings infected with CiLV-C according to Rodrigues et al. (3). Fifteen days after the mites were transferred, spotted yellowish symptoms were observed on leaves of plants of S. violaefolium and similar symptoms were observed after 25 days on citrus leaves. The symptomatic tissues were studied using transmission electron microscopy. Particles typical of CiLV-C were observed in samples from both p...Continue Reading
