Citrus Tristeza virus (CTV) is a member of the genus Closterovirus
and triggers one of the deadliest pathogenic diseases found in citrus fruit (Djelouah and D'Onghia, 2000).
(2002), reported meristem alone as less effective, whereas obtained complete eradicaiton of citrus exocortis pospiviroid (CEVd) and citrus tristeza closterovirus
(CTV) by using thermotherapy in combination with meristem culture.

from Nicotiana tabacum.
Currently, there are about five distinct species of grapevine leafroll-associated viruses (GLRaVs) found in cultivated grapes: GLRaV-1, 3, 4 in the genus Ampelovirus; -2 in the genus Closterovirus
, and -7 in the genus Velarivirus (International Committee on Taxonomy of Viruses (ICTV), 2016).
Prospects of classical cross protection technique against Citrus tristeza closterovirus
They used 'Chardonnay' and 'Lakemont Seedless' infected with Grapevine leafroll associated virus-3 (GLRaV-3, an Ampelovirus), 'Pinot gris' and 'Sauvignon Blanc 316' infected with Grapevine leafroll associated virus-2 (a Closterovirus
), and another clone of 'Sauvignon Blanc' infected with both Grapevine leafroll associated virus-1 (an Ampelovirus) and GLRaV-3.
As amostras foram avaliadas quanto a presenca de Foveavirus: GRSPaV; Vitivirus: GVA, GVB; Closterovirus
: GLRaV-2; Ampelovirus: GLRaV-3, GLRaV-4; Maculavirus: GFkV; Marafivirus: GRVFV e Nepovirus: GFLV por RT-PCR em tempo real (TaqMan).
vaporariorum can also act as a vector by transmitting viruses to plants, viz., Beet pseudo yellow virus (BPYV) (Closterovirus
) (Duffus et al.
2005 Biological, serological and molecular characterization of three isolates of citrus tristeza closterovirus
introduced into Morocco EPPO BULLETIN 35: 511.
2002, Afechtal, 2013).Citrus tristeza virus (CTV) belongs to the genus Closterovirus
that triggers one of the most deadliest pathogenic disease of citrus fruit (Djelouah and D'Onghia, 2000).
O CTV pertence ao genero Closterovirus
e e transmitido por material propagativo infectado e por afideos, sendo o pulgao-preto-dos-citros (Toxoptera citricida Kirkaldy) o vetor mais importante no Brasil, cujo controle nao e eficiente.
