  • Patent number: 10717984
    Abstract: The present invention relates to a method of controlling the flowering time of a plant by regulating the formation of the SVP-FLM-? protein complex, based on the finding that the SVP-FLM-? protein complex is a regulating factor for plant flowering that senses small changes in ambient temperature. The FLM-? RNAi and SVP RNAi for controlling flowering time according to the present invention can be used to control flowering time by inhibiting the expression of FLM-? and SVP or regulating the interaction therebetween, and thus, they can prevent a decrease in crop production or a change in the ecosystem from being caused by a sudden change in temperature.
