Phenotype
Pleiotropic phenotype: slow growth; leaves and bracts are small and upward curling; precocious transition from inflorescence to flower formation under short-day conditions; fewer secondary inflorescences than the wild-type with bracts subtending the first flowers that form on the primary inflorescence (suggesting that flowers initiate in the position where secondary inflorescences would normally form); plants occasionally form a flower immediately from the rosette leaves; numerous defects in floral organ formation including altered floral organ number, position, and identity; splayed-open floral buds; the first-whorl sepals are splayed open instead of enclosing the remaining floral organs due to outward bending of the pointy sepal tips; the fourth-whorl carpels are partially unfused at the tip, with stigmatic tissue missing or placed internal to the carpel tip; carpel defects are first observed in stage 7, which are funnel shaped rather than cylindrical; female sterile due to ovule growth arrest at megagametogenesis; reduced male fertility and reduced anther dehiscence; inflorescences terminate in central carpelloid structures after forming 2-20 flowers; reduced plant height compared to wild type; no gross alterations in root phenotype.
