“…Closteroviruses represent probably the most heterogeneous group of plant viruses Bar-Joseph et al, 1979). The type strains of BYV, CTV and LIYV have signature similarities for defining related viruses, that is a 5'-encoded polyprotein with protease, MT, HEL, and a + 1 translation frameshift to produce RdRp.…”

“…CTV is normally transmitted by aphids or by grafting and is limited to the phloem of infected trees. CTV is the largest member of the closterovirus group, which is characterized by a long flexuous rod morphology (Bar-Joseph et al, 1979). The virion consists of a single-stranded mRNA, about 20 000 bases in length, encapsidated by a single type of coat protein (Lee & Calvert, 1987;Lee et al, 1988), which has a reported Mr of 26000 (Nagel et al, 1982;Lee et al, 1988) or 27000 (Dulieu & Bar-Joseph, 1990) from in vitro translation studies.…”

“…Con la purificación del virus y la producción de anticuerpos contra la proteína de la cápsida, se empezaron a utilizar para el diagnóstico rutinario inmunoensayos tipo ELISA (Gonsalves et al, 1978;Bar-Joseph et al, 1979;Cambra et al, 1979Cambra et al, , 1991Vela et al, 1986;Permar et al, 1990;Garnsey et al, 1993;Nikolaeva et al, 1998). Posteriormente, tras la obtención de secuencias del genoma de CTV se desarrollaron diversas técnicas de diagnóstico basadas en la detección específica del RNA viral, como son las técnicas de hibridación molecular con sondas de DNA o RNA (Rosner y Bar-Joseph, 1984;Narváez et al, 2000;Barbarossa y Savino, 2006) y RT-PCR (Nolasco et al, 1993;Olmos et al, 1999).…”

“…El virus de la tristeza de los cítricos (Citrus tristeza virus, CTV), es un miembro del género Closterovirus, familia Closteroviridae (Bar-Joseph et al, 1979;Bar-Joseph y Lee, 1989a;Martelli et al, 2000). Los viriones de los miembros de esta familia son de morfología filamentosa (11-12 x 800-2000 nm), presentan genomas formados por una, dos o tres moléculas de RNA de cadena sencilla y polaridad positiva, que encapsidan separadamente, y al menos dos proteínas de cápsida (CP y CPm), cuyas subunidades se ensamblan separadamente en cada extremo del virión formando una estructura helicoidal que le da una morfología similar a una serpiente de cascabel (Boyko et al, 1992;Agranovky, 1996;Febres et al;.…”
