Examples of mutant phenotypes in the M2 population. Examples of morphological mutants illustrating the mutation spectrum observed in the N. caerulescens M2 populations. A-D abnormal leaf shape and organization; E-H chlorophyll phenotypes; I-J apetala-like phenotype; K agamous-like” double flower” phenotype; L cauliflower-like phenotype; M no side shoots, N non-vernalisation requiring early flowering mutant, O wild-type SF inflorescence, P wild-type SF rosette (2 months old). Additional mutant phenotypes are described in Supplementary Fig. S1.
