摘要
Compositions and methods for modulating plant development and for increasing yield in a plant are provided. The compositions include a PC4 sequence. Compositions of the invention comprise amino acid sequences and nucleotide sequences selected from SEQ ID NOS: 1 and 2 as well as variants and fragments thereof. Nucleotide sequences encoding the PC4 molecule are provided in DNA constructs for expression in a plant of interest are provided for modulating the level of a PC4 sequence in a plant or a plant part are provided. The methods comprise introducing into a plant or plant part a heterologous polynucleotide comprising a PC4 sequence of the invention. The level of the PC4 polypeptide can be increased or decreased. Such method can be used to increase the yield in plants; in one embodiment, the method is used to increase grain yield in cereals.
