Phenotype

embryos have cotyledon primordia splayed apart; seedlings fail to unbend upon emergency from the seed coat causing poor germination without gibberellin in the medium; narrow cotyledons; presumptive shoot apical meristem (SAM) in embryo is enlarged; SAM produces very small narrow or radial leaves and infrequently terminates activity after production of a single pin-shaped organ (similar to the pinhead phenotype) which eventually becomes a crown of arrested organ primordia; axillary meristems are rare but frequency increase at low temperature; narrow or radial floral organs, not self fertile; backcrossed once to wild type; maintained as heterozygote.
