Weak allele. Embryos have altered placement of the root pole, slow embryonic development, longer cell cycles (~35%) and larger cells. Abnormal division of the hypophysis in the developing root of the embryo, generating a lens cell that is abnormal in shape or abnormally positioned; asymmetric development of the provasculature, this ultimately leads to an abnormal root pole which is displaced laterally causing the root-shoot axis to be at an angle to the long axis of the suspensor, giving the embryo a tilted appearance. Embryos are viable, have larger cells and nuclei than wild-type embryos but the same DNA content, mutant embryos are larger than wild-type embryos at the same developmental stage. Plants have slow growing roots, slightly delayed flowering, altered floral phyllotaxis, reduced number of ovules, abnormally developing ovules, and reduced fertility.
