SEM Arabidopsis InflorescenceSEM of a wild-type Arabidopsis inflorescence.The inflorescence meristem is hidden, but if you follow the floral buds from largest to smallest you can identify its approximate location.

SEM ap1 mutantSEM of an apetala1 mutant Arabidopsis inflorescence. As the name implies, petals are missing in this mutant.

SEM ap1 cal mutantSEM of an apetala1 cauliflower mutant Arabidopsis inflorescence. In the double mutant, the inflorescence meristem produces more inflorescence meristems, not floral meristems. This same iterative branching is seen in broccoli and cauliflower plants.How does this SEM compare with the SEM of a cauliflower inflorescence? Can you identify the numerous inflorescence meristems?
