WRKYs are a multigenic family of plant-specific transcription factors that are involved in regulating plant development and various stress responses. However, how WRKY genes evolve is not fully understood. The study of this family in grapevine is also incomplete, and the numbering of the WRKYs under investigation has been different in many publications, which has led to a great deal of confusion. This work identified 62 WRKY genes from Vitis vinifera, described the gene structure, assessed amino acid variability between different cultivars for the first time, studied WRKY evolution, and carried out a complete revision of numbering. We propose that WRKY has evolved through two dynamic phases of complexity and simplification. For the first time, chimeric WRKY genes have been found, which may play a specific role in regulating different processes.
