Abstract: The present disclosure provides 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 more deeply incised blades, dehiscent corollas, and higher ornamental value. In the present disclosure, overexpression of the sweetpotato IbSAP15 gene in sweetpotato can deepen leaf incisions, 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.

Abstract: An aqueous dispersion of a silicone pressure sensitive adhesive base can be combined with a curing agent and cured to form a silicone pressure sensitive adhesive. The aqueous dispersion of the silicone pressure sensitive adhesive base includes a bis-hydroxyl-terminated polydiorganosiloxane; a polyorganosilicate resin; cumene; a surfactant; and water. A curing agent such as a peroxide compound or an aminosilane may be combined with the aqueous disperison of the silicone pressure sensitive adhesive base to form a silicone pressure sensitive adhesive composition. A pressure sensitive adhesive article may be formed by a method including coating a surface of a substrate with the silicone pressure sensitive adhesive composition, removing water, and curing the silicon pressure sensitive adhesive composition to form a silicone pressure sensitive adhesive on the surface of the substrate.

Abstract: A method for preparing a curable silicone pressure sensitive adhesive emulsion includes preparing a dispersion of benzoyl peroxide and a phenoxy-functional alcohol and thereafter combining the dispersion with the other starting materials of the emulsion.
