Transgenic resistance to Citrus tristeza virus in grapefruit

Plant Cell Reports, 2007
Grapefruit (Citrus paradisi) transgenic plants transformed with a variety of constructs derived from the Citrus tristeza virus (CTV) genome were tested for their resistance to the virus. Most transgenic lines were susceptible (27 lines), a few were partially resistant (6 lines) and only one line, transformed with the 3' end of CTV was resistant ...

Progress on strain differentiation of Citrus tristeza virus and its application to the epidemiology of citrus tristeza disease

open access: yesVirus Research, 2000
Citrus tristeza virus (CTV) occurs in most citrus producing regions of the world, and it is the most serious viral pathogen of citrus. With the recent establishment of the brown citrus aphid, Toxoptera citricida, its most efficient vector, on Madeira Island (Portugal) and in Florida (USA) and the countries of the Caribbean Basin, the impact of CTV is ...

Presence of Citrus tristeza virus in Croatia

Options méditerranéennes. Série B: études et recherches, 2009
Forty-five samples, mostly Satsumas, from 11 orchards, 2 nurseries and a collection planting were tested by ELISA or IC/RT-PCR for the presence of Citrus tristeza virus (CTV). The preliminary survey confirmed the presence of CTV in 17 out of 45 field samples that were mostly asymptomatic, as expected in plants grafted onto trifoliate rootstocks.

Production of Antibodies to Citrus Tristeza Virus in Transgenic Citrus

1995
Citrus tristeza virus (CTV) is the most important virus disease of citrus in the world. CTV causes death of trees on sour orange rootstock and/or stem pitting of scions regardless of rootstock which results in trees of low vigor, reduced yield with reduction in size and quality of fruit. The purpose of this project was to produce monoclonal antibodies (
