During the presentation I felt that the slide that was most appreciated was: “Why Mexico? Because we want you there!”. Indeed, we are very happy that you are coming to Guanajuato, Mexico for the 6th International Geminivirus Symposium and the 4th International ssDNA comparative virology Workshop. Welcome. What is the formula, the recipe to make a scientific meeting a success? The first and key ingredient that has been always present in the previous Symposia: an excellent academic program. And that means you. We have registered more than 150 attendants from all around the World, we have scheduled more than 30 keynote / plenary talks and have received more than 100 abstracts. The contributions received for this meeting reflect interesting, informative major tendencies on ssDNA virology research. Virus-host interaction and virus diversity / evolution are favorite research areas this year. We will be presented also with new methodologies and technological platforms that are helping us to generate more data than ever, that facilitate new discoveries. In my opinion this is excellent news. Yes, we are characterizing new viruses, detecting new pathogenic entities, and learning how these pathogens evolve, and interact among themselves But we are also learning like never before how these entities interact with the host cells, with their machinery, and at the end, how they cause disease. Which is probably what the general population is interested in. As in many other scientific disciplines, bioinformatics is becoming a major player in our research, not only to analyze and compare the now hundreds of virus genomes, but also how to assemble new genomes without cloning them, how to trace back an important pathogen to its origins, and even how to understand the meaning of hundreds of genes that are over- or under-expressed in a infected host cell. Finally, another learning experience from analyzing geminivirus literature is that research has become more and more an interdisciplinary and collaborative activity. We hope that this meeting will be “the origin”, “the source”, “a melting-pot”, for new and productive collaborations that will benefit everybody. To those with years of experience, let us show the students, those that represent the next generations, the advantages of collaboration and coordinated efforts. That can be also an important legacy. Enjoy Guanajuato and remember this is also a Birthday Party.
