e1“The ensuing modified BCE models for the mutants supported instances of neofunctionalization (e.g., B-class genes expressed ectopically in sepals), partial redundancy (E-class), or subfunctionalization (C-class) of paralogs.”
Title

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 Candidate floral MADS-box genes lacked deleterious coding-region mutations.
- Mechanism The absence of coding mutations suggested cis-regulatory or trans-acting mutations.
- Observation Double-flower mutants had transposon insertions or activity in regulatory introns of AG orthologs.
- 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.
