Other claims from this paper (8)
- Observation Floral mutants showed altered expression of floral MADS-box genes.
- Observation Modified BCE models supported neofunctionalization of B-class paralogs.
- Observation Modified BCE models supported partial redundancy of E-class paralogs.
- Observation Modified BCE models supported subfunctionalization of C-class paralogs.
- Observation Candidate floral MADS-box genes lacked deleterious coding-region mutations.
- Mechanism The absence of coding mutations suggested cis-regulatory or trans-acting mutations.
- Observation Single amino acid substitutions were found outside identified DNA-binding and PPI motifs.
- Mechanism The authors infer transposon activity and regulatory mutations likely underlie floral homeotic phenotypes.
