Allele: Locus: AGI code:
  • ap1-5




weak allele; homeotic conversion of sepals (first whorl), with marked difference between the morphology of the medial and lateral first-whorl organs; medial first-whorl organs vary acropetally from wild-type sepals or central phylloid- marginal petaloid mosaic to leaf-like, bract-like, or bract-like-carpel-stamen mosaic; lateral first-whorl organs are bract-like or absent in the more apical positions; second-whorl in basal flowers is wild type, in apical flowers is absent but when present they are petal-stamen mosaic or wild-type stamens; phenotype varies acropetally, with more complete conversions in basal flowers and at low temperature.
