Reaction of citrus rootstocks to Meloidogyne javanica.
The response of Citrus spp. and related rootstocks to a population of Meloidogyne javanica was evaluated in a screenhouse experiment. Palestine and Rangpur lime, rough lemon, sour orange, Sexton and Thentriton tangelo, and Volkamer lemon were not infected by M. javanica. Galls and tip swellings were observed on the roots of Poncirus triloliata and Troyer citrange. There was no evidence of nemat...
متن کاملCitrus tristeza virus-host interactions
Citrus tristeza virus (CTV) is a phloem-limited virus whose natural host range is restricted to citrus and related species. Although the virus has killed millions of trees, almost destroying whole industries, and continually limits production in many citrus growing areas, most isolates are mild or symptomless in most of their host range. There is little understanding of how the virus causes sev...
متن کاملPast and future of a century old Citrus tristeza virus collection: a California citrus germplasm tale
Citrus tristeza virus (CTV) isolates collected from citrus germplasm, dooryard and field trees in California from 1914 have been maintained in planta under quarantine in the Citrus Clonal Protection Program (CCPP), Riverside, California. This collection, therefore, represents populations of CTV isolates obtained over time and space in California. To determine CTV genetic diversity in this conte...
متن کاملThe Complex Genetics of Citrus tristeza virus
The 2000 x 11 nm long bipolar flexuous filamentous particles of Citrus tristeza virus (CTV) (genus Closterovirus, family Closteroviridae) (Figure 1) contain a single-stranded positive-sense RNA genome of 19.3 kb, which is encapsidated in two different capsid proteins that coat the opposite ends of the virions [1, 2]. CTV is the largest identified RNA virus infecting plants and the second larges...
متن کاملEpidemiology of Citrus tristeza virus in nursery blocks of Citrus macrophylla and evaluation of control measures
The control of Citrus tristeza virus (CTV), the causal agent of tristeza disease, is essential to guarantee a productive citrus industry. The specific features of a nursery block make the control of the natural spread of viruses transmitted by vectors more difficult. Thus, the knowledge of the epidemiology of CTV in nursery blocks is basic to the design control strategies of the disease. Two ex...
