Abstract: Soyasaponin-related Kompetitive Allele Specific polymerase chain reaction (KASP) markers and an application thereof are provided in the present application, belonging to the technical field of molecular breeding. The KASP markers include one or two of S07_43139773G/T, and S07_43139033A/G; the S07_43139773G/T comprises a base of G/T at a position of 43139773 bp on chromosome 7 of a soybean genome, the S07_43139033A/G comprises a base of A/G at a position of 43139033 bp on the chromosome 7 of the soybean genome. The KASP markers are applied to improve soyasaponin germplasm breeding.

Abstract: A method for controlling a smart device includes: judging whether a control terminal and a selected smart home device are located in a same local area network; establishing a connection to a smart home device management platform over the local area network if the control terminal and the selected smart home device are located in the same local area network, the smart home device management platform recording one or a plurality of smart home devices; enabling a virtual private network (VPN) module and establishing a connection to the smart home device management platform over a VPN channel if the control terminal and the selected smart home device are not located in the same local area network; and controlling a corresponding smart home device by the smart home device management platform.
