CONSTITUTIVE PHOTOMORPHOGENESIS 1 (COP1) NUCLEIC ACID SEQUENCE FROM ZEA MAYS AND ITS USE THEREOF

摘要

The present invention relates to an isolated COP1 nucleic acid sequence from a maize plant and the isolated COP1 nucleic acid sequence is named as ZmCOP1. The present invention also relates to a method of using the ZmCOP1 nucleic acid sequence to control the shade avoidance response of a crop plant for high density farming and yield enhancement.

主权项

1. A recombinant DNA construct comprising A COP1 nucleotide sequence encoding a polypeptide having an amino acid sequence that has at least 90% sequence identity to SEQ ID NO: 13; SEQ ID NO: 15 OR SEQ ID NO: 17 or a functionally equivalent fragment thereof,
said COP1 nucleotide sequence being operably linked upstream (5′) to a promoter and downstream (3′) to a regulatory element, wherein upon its transformation into a plant, said construct causes reduction of endogenous COP1 protein level.
