A model for floral organ development in Arabidopsis

Ming Yang

Testable predictions: 1) The cell division rates and/or durations of cell division in the mutants are less than the division rate and/or duration in the wild type. 2) The total number of cell layers between the centers of two fused organs will be fewer than that between two separate organs. 3) Because two adjacent organ domains competitively specify the identities of the overlapping cell layers, these cell layers may attain “confused” identities in the fused organs. All these predictions can be experimentally tested. If experimental results agree with the predictions, the model will be very useful and enable new understanding of the mechanism governing floral organ development.
