Provided is a StSCI protein for changing the self-incompatibility of diploid potato materials, wherein the amino acid sequence of the StSCI protein includes or consists of the following sequence: 1) the amino acid sequence represented by SEQ ID NO: 1; or 2) a functional homologous sequence having at least 95% sequence identity with the amino acid sequence represented by SEQ ID NO: 1; or 3) a protein in which one or more (e.g., 1-10) amino acids are added, deleted, or replaced in the amino acid sequence represented by SEQ ID NO: 1 and has the activity of inhibiting self-incompatibility. The advantage of the application is that the StSCI protein may inhibit the cytotoxicity of multiple types of S-RNase, which is hereditary and fundamentally overcomes the defect of self-incompatibility of diploid potatoes, thereby facilitating to realize the cultivation of a high-generation homozygous inbred line of diploid potatoes.

Disclosed is a method for access authentication. The method includes: receiving profile information of a visitor through a server, and generating a visitor code and transmitting the same to a visitor terminal, and generating a random code based on a valid visitor code, and receiving a decoding result based on decoding the random code and the visitor code by the visit terminal, and predetermining an access authority for the visitor for a predetermined time as the decoding result is successfully matched.

Method, server, smart terminal and storage device for access authentication

Method and apparatus for enabling precise focusing are provided. The method includes obtaining an operation time of the photographing device in real time by a processor, searching a relationship table of preset times and focus range based on the obtained operation time to obtain a focus range corresponding to the obtained operation time; sending the obtained focus range to a driver by the processor, adjusting the distance between a lens and an image sensor based on the focus range by the driver, so that the lens may be located in the focus range, and to adjust the focus range in real time and improve the accuracy of focusing between the lens and the image sensor.
