Abstract: Plant viruses, in particular Potyvirus and Ipomovirus, are pathogens that cause serious economic losses in agricultural crops. Knowing their gene products can be useful to design strategies to control these pathologies. There is a need to increase knowledge about viral plant pathogens, automating the recording and analysis of their genomes, at a time when genome sequencing is very accessible to researchers. Both the uORFs and the slip zones of the polymerase, are events that respond to an evolutionary need of viruses subject to a certain type of condition. Many of these events generate strategies for viruses to improve their adaptability and infective capacity. Knowledge of these areas helps us to understand their biology and prevent their potential risks. In this sense, this work attempts to resolve some of these issues. The uORFs are searched in the 5'-UTR zones of Ipomovirus. Additionally, FIMO and gkm-SVM are also tested as tools for the search of polymerase slippage zones. Finally, on the use of these two tools, it is found that gkm-SVM is a powerful classification algorithm much more accurate than FIMO in the search for polymerase slippage zones, however, the training costs of the algorithm are much higher than the search for motives using FIMO.
