Abstract: A virulence factor FsPL gene from the sugarcane pokkah boeng disease and use thereof are provided. The virulence factor FsPL gene from the sugarcane pokkah boeng disease has a sequence set forth in SEQ ID NO: 1. The present invention reveals a gene FsPL that is related to the pathogenicity of F. sacchari. Preliminary analysis shows that the deletion of the gene affects the ability of hyphae to penetrate and further affects the pathogenicity of pathogens. This provides a basis for the molecular mechanism of the pathogen infection and pathogenic process.

Abstract: A battery cell includes: a shell, including a first wall; an electrode assembly, disposed inside the shell; and a terminal assembly, including an electrode terminal and an elastic member. The electrode terminal includes a fixed portion for electrical connection with the electrode assembly and a movable portion for electrical connection with a current collecting component. The fixed portion is fixedly disposed on the first wall. The movable portion is movably disposed on the first wall, and has a first position in contact with the fixed portion and a second position separated from the fixed portion. The elastic member is used for applying elastic force to the movable portion to maintain the movable portion in the first position. The movable portion is configured to move from the first position to the second position against the elastic force when internal pressure of the battery cell reaches a threshold.

Abstract: The invention provides a method for identification of alleles. In this method, genomic DNA is used as target. Multiple allele-specific PCR amplification are carried out with a group of primers comprising one or more allele-specific primers for a target gene, a universal primer, and a common primer; and a DNA polymerase without 5? to 3? exonuclease activity. The PCR products are hybridized with tag probes immobilized on a DNA chip. Results are determined based on the signal intensity and the position of the probe immobilized on the array. Each allele-specific primer comprises a unique tag sequence at the 5? end. Each tag probe immobilized on the DNA chip comprises a sequence identical to its corresponding tag sequence; and each tag probe hybridizes only with the complementary sequence in the PCR amplification product.
