US 8,785,724 B2 · Regulator for flowering time, transgenic plant transformed with the same, and method for regulating flowering time

Abstract

The present invention relates to a flowering-time and/or stem elongation regulator isolated from rice, which is selected from OsMADS50, OsMADSS1, OsMADS56, OsMADS14, OsTRX1, OsVIN1, OsCOL4 and OsCOLS, a DNA construct containing the regulator, a transgenic plant, a part thereof, and plant cell transformed with the DNA construct, and method to control flowering-time and/or stem elongation using the regulator. In the present invention, the flowering-time and/or stem elongation can be controlled, and thereby, various agricultural benefits obtained.
