SORGHUM MATURITY GENE AND USES THEREOF IN MODULATING PHOTOPERIOD SENSITIVITY

摘要

Compositions relating to the sorghum maturity gene 1 (Ma1) and expression control sequences and methods of use thereof are provided. The compositions can be used to modulate flowering and photoperiod sensitivity in a plant. For example, methods are provided for developing genetically modified plant varieties in which flowering is accelerated, delayed or prevented. Methods are provided for treating a plant in order to delay flowermg in the plant. Methods of placing a polynucleotide of interest, such a gene, under photoperiod sensitive control or photoperiod insensitive control are also provided. Screening methods are for identifying chemical agents that can modify photoperiod sensitivity are also disclosed.
