Fig. 4. Adult and flower phenotypes of different enp pid combinations. Genotypes are indicated for adult plants (upper row) and their corresponding flowers or pin-ends (middle and bottom row). The pin-ends in the third row belong to plants of the two adjacent genotypes, as indicated by white arrows. The black arrow indicates a flowerless blind ending stem of pid-9 +/pid-9 +. The black arrowhead indicates flower structures on a stem of a pid-9 enp/pid-9 enp plant. White arrowheads refer to sepal fusions. Scale bars: 1 cm (upper row); 1 mm (middle and lower rows).
