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.
