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.- Pasture persistence is a key determinant of the economic and environmental performance of pastoral animal production systems. Large and deep root systems that help resist summer water stress have been proposed as a relevant trait for vegetative persistence of perennial temperate forage species growing in subtropical climates or under future climatically challenging scenarios. In a previous study [Jauregui et al., 2017. Persistence of tall fescue in a subtropical environment: Tiller survival over summer in response to flowering control and nitrogen supply. Grass and Forage Science 72, 454-466] we have shown that nitrogen fertilization and grazing management aimed at 'control flowering' increased the survival of tall fescue tillers during harsh summers in Uruguay (lat. 32°S). Here we assessed: (i) to what extent tiller survival is mediated by root system size in spring and (ii) what consequences tiller survival entails for root mass, depth and morphology the following autumn. In two field experiments, significant increases in tiller survival in response to nitrogen fertilization and grazing management (+60% and +80% in 2011/12 and 2012/13, respectively) were not related to concomitant effects on the size or depth of the root system in spring (p >.10). Even when six-fold within-treatment variation in root mass was observed, within-treatment variation in summer tiller survival was little affected (<15%, p =.08). In turn, differences in tiller survival over summer affected little root system characteristics the following autumn. Therefore, we found scant support for the hypothesis that large and deep root systems contribute to survival of tall fescue tillers in this subtropical humid climate. Except for soils with less than 30 mm of plant available water holding capacity, summer water deficits did not induce severe tiller mortality in tall fescue in this climate. © 2024 Wiley-VCH GmbH.
