The present invention provides methods to increase crop yield utilizing transgenic complementary paired genes controlling plant growth and yield. The specific genes increase female reproductive organs and are paired with genes responsible for modifying the growth of non-yield specific plant tissues. Plants, plant progeny, seeds and tissues created by these methods are also described. Polynucleotides encoding the paired sequences are provided for expression in a plant of interest. Expression cassettes, plants, plant cells, plant parts and seeds comprising the sequences of the invention are further provided. In specific embodiments, the polynucleotide is operably linked to a constitutive promoter.
