We have characterized the genetic and molecular origin of the reiterated reproductive meristem (RRM) somatic variant phenotype of grapevine cultivar Carignan. Here, we show that the extreme cluster proliferation and delayed anthesis observed in this somatic variant is caused by a single dominant mutation. Transcriptional profiling of Carignan and RRM plants during early stages of inflorescence development demonstrated the overexpression of a few regulatory genes, including VvTFL1A, a close TFL1  ...[more]
