RESUMEN.- En la agricultura uruguaya se ha tornado cada vez más frecuente la ocurrencia de fallas control de yerba carnicera (Conyza spp.) después de la aplicación de diferentes herbicidas, entre los cuales el glifosato y a los inhibidores de la ALS (acetolactato sintasa). El objetivo de este trabajo fue confirmar la ocurrencia de resistencia de Conyza spp. a los herbicidas glifosato, diclosulam y clorimuron, a partir de ensayos de curva de dosis respuestas. -------- SUMMARY.- In Uruguayan agriculture, the occurrence of control failures of hairy fleabane (Conyza spp.) after the application of different herbicides, including glyphosate and ALS (acetolactate synthase) inhibitors, has become more and more frequent. The objective of this work was to confirm the occurrence of resistance of Conyza spp. to the herbicides glyphosate, diclosulam, and chlorimuron, from dose-response curve assays. |

ABSTRACT.
Xylella fastidiosa inhabits the plant xylem, a nutrient-poor environment, so that mechanisms to sense and respond to adverse environmental conditions are extremely important for bacterial survival in the plant host. Although the complete genome sequences of different Xylella strains have been determined, little is known about stress responses and gene regulation in these organisms. In this work, a DNA microarray was constructed containing 2,600 ORFs identified in the genome sequencing project of Xylella fastidiosa 9a5c strain, and used to check global gene expression differences in the bacteria when it is infecting a symptomatic and a tolerant citrus tree. Different patterns of expression were found in each variety, suggesting that bacteria are responding differentially according to each plant xylem environment. The global gene expression profile was determined and several genes related to bacterial survival in stressed conditions were found to be differentially expressed between varieties, suggesting the involvement of different strategies for adaptation to the environment. The expression pattern of some genes related to the heat shock response, toxin and detoxification processes, adaptation to atypical conditions, repair systems as well as some regulatory genes are discussed in this paper. DNA microarray proved to be a powerful technique for global transcriptome analyses. This is one of the first studies of Xylella fastidiosa gene expression in vivo which helped to increase insight into stress responses and possible bacterial survival mechanisms in the nutrient-poor environment of xylem vessels.
