Population structure of Citrus tristeza virus from field Argentinean isolates
The results showed a high intra-isolate sequence variability suggesting that re-infections could contribute to the observed variability and that the host can play an important role in the selection of the sequence variants present in these isolates.

Highly morphogenic callus cultures were isolated from stamens of a wild peanut species, Arachis paraguariensis, and grafting to stems of rooted seedlings was used to obtain plants from regenerated shoots.
Genetic transformation of sweet orange with the coat protein gene of Citrus psorosis virus and evaluation of resistance against the virus
21 independent lines of sweet orange expressing the coat protein gene of CPsV and five of them were challenged with the homologous CPV 4 isolate, but so far, no resistance or tolerance has been found in any line after 1 year of observations.
Resistance to Citrus psorosis virus in transgenic sweet orange plants is triggered by coat protein-RNA silencing.

Generation of Sweet Orange Transgenic Lines and Evaluation of Citrus psorosis virus‐derived Resistance against Psorosis A and Psorosis B
Citrus psorosis is a widespread serious disease of citrus caused by Citrus psorosis virus (CPsV). In Argentina and Uruguay, this disease is spread by an unknown vector and there is no natural…
RESULTS FROM A THREE YEARS FIELD TRIAL PLANTED AT CONCORDIA, ARGENTINA USING TRANSGENIC ROOTSTOCKS POTENTIALLY RESISTANT TO TRISTEZA
Improved Detection of Citrus psorosis virus and Coat Protein‐Derived Transgenes in Citrus Plants: Comparison Between RT‐qPCR and TAS‐ELISA
The sensitivity and reliability of quantitative CPsV detection were improved with greater speed using commercial reagents, and the sensitivity was three orders of magnitude higher than that of TAS-ELISA.
