When mutations in CUP-SHAPED COTYLEDON1 (CUC1) and CUC2 are combined, severe defects involving fusion of sepals and of stamens occur in Arabidopsis flowers. In addition, septa of gynoecia do not fuse along the length of the ovaries and many ovules have their growth arrested. CUC2 is expressed at the tips of septal primordia during gynoecium development and at the boundary between nucellus and chalaza during ovule development. These expression patterns are partially consistent with the phenotype of the mutant gynoecium. CUC2 mRNA is also shown to be expressed at the boundaries between meristems and organ primordia during both the vegetative and reproductive phases. This expression pattern indicates that CUC2 is generally involved in organ separation in shoot and floral meristems.
