The seminal reports of somatic embryogenesis in the umbellifers Oenanthe aquatica by Harry Waris in 1957 (Krikorian and Simola, Physiol Plant 105:348–355 (1999)) and carrot (Steward et al., Am J Bot 45:693–703 (1958)) paved the way for current studies on the mechanisms involved in the transition of somatic cells to the embryogenic state for many species (Fehér et al., Plant Cell Tiss Org 74:201–228, 2003; Elhiti and Stasolla, Plant embryo culture: methods and protocols, Humana Press, New York, 2011; Fehér, Biochim Biophys Acta 1849:385–402, 2015). Somatic embryogenesis has been a focal point of research in plant development. This process relies on somatic cell totipotency (i.e., the capacity to regenerate the entire plant from single somatic cells), and it has been long used in biotechnological breeding techniques as an efficient system for regenerating plants in a large-scale basis. Also, because …
