Provided is the use of sweetpotato IbSAP15 gene in regulating leaf shape and flower shape of sweetpotato. Compared with the control, Ipomoea batatas cv. Xuzishu 8, IbSAP15-overexpressing lines have deeper sinuses, dehiscent corollas, and higher ornamental value. In the present disclosure, overexpression of the sweetpotato IbSAP15 gene in sweetpotato can increase a sinus depth of a sweetpotato leaf, make trumpet-shaped corollas dehiscent, and change leaf shape and flower shape of sweetpotato. The present disclosure is suitable for developing sweetpotato germplasms with different leaf shape and flower shape and promotes ornamental flowering/foliage sweetpotato breeding.
A method for producing flowers with dehiscent corolla in sweetpotato, comprising inserting a sweetpotato gene into plant expression vector pGWB12 and then introducing the plant expression vector into the sweetpotato such that the sweetpotato gene is overexpressed in the sweetpotato;
