About the GyDB

The GyDB is an ongoing research and educational project that was created in 2005 in an aim to contribute to the ongoing research on viruses and mobile genetic elements (MGEs). With the information included in the database, we aim to:

  • Classify the diversity of viruses and MGEs based on their phylogenetic profiles in the context of the tree of life.
  • Cast some extra light on their molecular biology.
  • Characterize the impact they have on their hosts.
  • Integrate all this knowledge in an open access, editable wiki-like database so the scientific community can help expand the topics of study by contributing with their knowledge and new findings.

Given the complexity and the wide diversity of viruses and MGEs, a project of this scope must be addressed step-to-step. As our first GyDB study goal, we addressed the order of Ortervirales, which includes all retroviruses of vertebrates, Caulimoviruses (plant viruses) and their related families of LTR retrotransposons: Ty1/Copia (Pseudoviridae) and Bel/Pao (Belpaoviridae). All the information pertaining to these viruses and MGEs is available in the current GyDB release. Our goal is to keep adding new scientific knowledge to this field as it expands.

Why donate?

The research we undertake at GyDB is primarily financed through grants and collaborations with research centres. However, as an open access database, the GyDB requires both IT servers and curators working daily to maintain the infrastructure up to date and freely available for everyone. While incredibly helpful, research grants usually only include a small budget overhead to maintain the projects operative in the long run after they have been released. In this way, every additional contribution, big or small, makes a difference and helps us keep the GyDB operative over the years.


Thank you very much indeed.
