Phenotype

Plants exhibit reduced lateral shoot meristems (LSMs) of rosette and cauline leaves; approximately 70% of cauline leaves lack a lateral meristem and 16% fail to produce meristems in the axils of any rosette leaves; decapitation of the primary shoot meristem (SAM) fails to stimulate axillary meristem formation; in the place of axillary meristems, the axils of affected leaves are usually bare, but occasionally develop a differentiated structure that is a leaf or a filamentous structure. Reduced flower meristem activity, while the majority of the flowers develop normally, 12% of the flowers initiate only a limited set of flower organs and appear to have a defective flower meristem; the inner organs are preferentially absent from flowers with defective meristems; in affected flowers, the floral meristem is reduced in size or nearly absent by stage 3 of flower development; other flowers are identical to wild-type. SAM size and the phyllotaxy of flanking primordia appear normal.
