POLINUCLEOTÍDEO ISOLADO, CASSETE DE EXPRESSÃO, PLANTA, MÉTODOS PARA AUMENTAR O NÍVEL DE UM POLIPEPTÍDEO EM UMA PLANTA, E PARA AUMENTAR O RENDIMENTO EM UMA PLANTA, E, POLIPEPTÍDEO ISOLADO

摘要

Compositions and methods for modulating flower organ development, leaf formation, phototropism, apical dominance, fruit development, initiation of roots, and for increasing yield in a plant are provided. The compositions include a ZmRR10_p sequence. Compositions of the invention comprise amino acid sequences and nucleotide sequences selected from SEQ ID NO: 2 as well as variants and fragments thereof. Nucleotide sequences encoding the ZmRR10_p are provided in DNA constructs for expression in a plant of interest are provided for modulating the level of a ZmRR10_p 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 ZmRR10_p sequence of the invention. The level of the ZmRR10_p 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.
