Stress responses and epigenomic instability mark the loss of somatic embryogenesis competence in grapevine.

Abstract excerpt

Somatic embryogenesis (SE) represents the most appropriate tool for next-generation breeding methods in woody plants such as grapevine (Vitis vinifera L.). However, in this species, the SE competence is strongly genotype-dependent and the molecular basis of this phenomenon is poorly understood. We explored the genetic and epigenetic basis of SE in grapevine by profiling the transcriptome, epigenome, and small...
