Abstract: A display panel includes a display layer, a photosensitive layer and an infrared mask. The display layer is configured to display an image, the display layer has light-transmitting portions, and the light-transmitting portions are configured to transmit infrared light. The photosensitive layer is disposed on a side of the display layer. The infrared mask is disposed on a side of the photosensitive layer proximate to the display layer, the infrared mask has hollowed-out regions, the hollowed-out regions are configured to make the infrared mask have a preset pattern, and a region in the infrared mask except the hollowed-out regions is configured to prevent transmission of the infrared light. The photosensitive layer is configured to receive infrared light passing though the hollowed-out regions and the light-transmitting portions, and convert the infrared light into an image signal.

Abstract: According to the present disclosure, on the basis of all existing mutations, the tenth glycine of a BC-PC-PLC is mutated into aspartic acid, a specific enzyme activity thereof is 83% higher than that of a sequence before the mutation, and protein expression and degumming activity of unit enzyme activity do not change, so as to further reduce manufacturing costs.

Abstract: Provided is a Pichia pastoris mutant strain for expressing an exogenous gene. Specifically, provided is a Pichia pastoris mutant strain comprising, with respect to Pichia pastoris mutant strain GS115 or CICC32806, one or more of the following six mutations: BQ9382_C1-2260, EKK deletions at positions 308-310, a hypothetical protein; BQ9382_C1-3800, E129K, 60S ribosomal subunit assembly/exported protein LOC1; BQ9382_C1-5700, I312M, mitochondrial external NADH dehydrogenase, type II NAD(P)H:quinone oxidoreductase; BQ9382_C2-3950, Q145X, an essential protein having a binding partner Psr1p and used for completely activating a general stress response; BQ9382_C3-2220, E188K, a hypothetical protein; and BQ9382_C3-4370, W196X, orotidine 5\?-phosphate decarboxylase. The provided Pichia pastoris mutant strain is an effective commonly employed host for exogenous expression, and can efficiently express different proteins, especially phospholipase and lipase.

Abstract: Disclosed are an amino acid sequence of myrmecia incise reisigl diacylgycerol acyltransferase, an encoding gene sequence and application thereof. Specifically, based on myrmecia incise reisigl transcriptome sequencing data, cloning to obtain full-length cDNA and full-length DNA sequences of a myrmecia incise reisigl diacylgycerol acyltransferase gene, and expressing the gene in yeast TAG synthesis defect strain H1246, finding that an encoded protein thereof has a capability for synthesizing a TAG, and using a substrate preference experiment to prove that the encoded protein of the gene tends to C18:1 fatty acid.
