e0“Rescue of the Arabidopsis C class mutant ag with the two maize genes confirms that their protein products have subfunctionalized, with ZAG1 better able to promote carpel identity, and ZMM2 better able to promote stamen identity”

- Intervention effect Maize B class genes rescued Arabidopsis B class mutants.
- Observation Maize B class proteins bound DNA as obligate heterodimers.
- Mechanism The maize and Arabidopsis B class proteins were interpreted as biochemically conserved.
- Mechanism The findings support interpreting the grass lodicule as a modified petal.
- Observation B class genes were expressed outside stamens in Streptochaeta foliar organs.
- Observation B class genes were expressed in Joinvillea petals.
- Observation B class genes were expressed in Chondropetalum petals.
- Intervention effect Maize ZAG1 more strongly promoted carpel identity in the Arabidopsis ag mutant.
- Observation A more recent Zmm2 duplicate, Zmm23, and zmm2 and zmm23 mutant alleles were isolated.
- Observation The maize zmm2 zmm23 double mutant had no phenotype.
- Intervention effect The maize zag1 zmm2 zmm23 mutant substantially enhanced the zag1 phenotype.
