REGULATION OF POLYCOMB GROUP GENE EXPRESSION FOR INCREASING SEED SIZE IN PLANTS

摘要

The present invention relates to regulation of Polycomb group gene expression to provide for larger seed size by plants. Applicants have discovered that an absence of seed specific Polycomb group gene expression in early seed development (from fertilization to late heart, torpedo or cellularization stage) and expression of the gene in late seed development, (any time after these developmental states), yields larger seeds. Methods and compositions for such manipulation are disclosed.
