Contenido: 	Resistance-breaking (RB) isolates of citrus tristeza virus (CTV) can replicate and move systemically in Poncirus trifoliata, a rootstock widely used for management of decline caused by CTV and other purposes. In Uruguay, severe CTV isolates are prevalent, and an RB isolate (designated as RB-UY1) was identified. In order to predict the implications of this genotype circulating in citrus crops grafted on trifoliate rootstocks, the aim of this work was to determine the biological and molecular characteristics of this isolate, the efficiency of its transmission by Toxoptera citricida, and its effects on plant growth performance of P. trifoliata. Our results show that RB-UY1 can be classified as a mild isolate, that it is phylogenetically associated with the RB1 group, and that it is efficiently transmitted by T. citrida. They also suggest that the RB-UY1 isolate should not affect the performance of citrus crops grafted on trifoliate rootstocks, although some growth parameters of P. trifoliata seedlings were affected four years after inoculation. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Austria, part of Springer Nature.
