ABSTRACT.
Prevalence of citrus tristeza virus (CTV) isolates causing severe stem pitting symptoms with a high diverse genetic composition represents a threat for citrus crops in Uruguay. This work aimed to characterize viral components of CTV populations segregated by single aphid (Toxoptera citricida) transmission (SAT). Thirty-nine SAT-derived sub-isolates were obtained from six CTV field isolates. Only eight were MCA13 non-reactive, and six of them, together with other three MCA13 reactive sub-isolates, were considered mild by the intensity of their reaction in ?Mexican? lime, ?Madam Vinous? sweet orange, ?Duncan? grapefruit and sour orange indicator plants. Fourteen sub-isolates, including two MCA13 non-reactive, were considered moderate, and the remaining sub-isolates were all MCA13 reactive and with severe reactions in the indicator plants. Sequence comparisons of the p20, p23 and p25 genes showed a high inter (among all isolates and their derived sub-isolates)- and intra (among each isolate and its derived sub-isolates)-specific evolutionary diversity, with the presence of the CTV strains VT, T3, RB, and NC in mixtures of their complex populations. Together, our data revealed the heterogeneity of the Uruguayan CTV populations in these CTV field isolates. The results provide additional biological and molecular information on the complex CTV populations in Uruguay and must be considered for improving the CTV management program.

Abstract:
Continuous agriculture (CA) has led to sustainability problems linked with production decreases, environmental contamination, crop failure and soil degradation in many regions of the world. Crop-pasture rotations (CPR) are management alternatives that contribute to environmental sustainability and productive diversification. Long-term experiments (LTE) play a major role in evaluations of the impact of different management practices on soil quality. However, the results can be misleading if the data are not adequately analyzed. A unique dataset of annual soil samples from a 55-year-old LTE was used 1) to evaluate the effects of a crop-pasture rotation on soil quality and crop productivity and 2) to provide robust statistical models to measure long-term changes in chemical soil quality parameters. Treatments were seven rotations, including CA or CPR with different proportions of pasture in the system (33%, 50%, or 66%). Soil organic carbon (SOC), total nitrogen (Ntot), exchangeable potassium (K) and soil pH have been determined annually since 1964, and the cumulative treatment effects were analyzed. Correlation structures showing the variance heterogeneity for the study years were tested for each parameter and condition. The longer the duration was of the pasture in the rotation, the slower the degradation was in the chemical soil quality. The CPR made a key contribution to sustainable agricultural diversification and intensification, leading to 30% higher crop yields and 19% and 14% greater SOC and Ntot concentrations, respectively, compared with CA. This LTE played a major role in the identification of strategies to increase soil fertility with diversified crop rotations through pasture integration, and statistically robust results were obtained that demonstrate the significance of frequent soil surveying over the long run.
