Phenotype

Plants exhibit pleiotropic phenotypes; most aerial organs are reduced in size: leaves and floral organs are small and plants are shorter compared to wild-type; small cells in mature leaves and petals; rosette leaves are pointed at the apical end and the edges tend to curl upward; delayed flowering; high flower density in inflorescence; reduced internode elongation in the stems; increased number of coflorescences; under long-day conditions (16 hour light/8 hour darkness), plants produce more cauline leaves with axillary inflorescences before producing single flowers on the inflorescence stems than wild type plants; reduced male and female fertility; anthers from early-arising flowers often fail to dehisce, although late-arising flowers do produce pollen, the amount of pollen produced appears to be greatly reduced; reduced seed set in siliques. Slight increase in rosette leaf number.
