Kalanchoë LEC1 proteins and their relationship with plantlet formation and seed viability. (A) Phylogenetic tree adapted from Gehrig et al. (38). (B–E) Phenotypes of representative species. (B) Species that do not produce plantlets (1). (C) Constitutive plantlet-forming species (2). (D) Semiconstitutive plantlet-forming species, which produce plantlets constitutively as well as upon stress induction (3). (E) Inducible plantlet-forming species in which plantlets are produced upon stress induction (4). Plantlet-forming species (5) possessing ancestral traits (3 and 4). +, presence; −, absence; *, one deletion; **, two deletions in LEC1 B domain.
