Abstract: A gene related to biosynthesis of ergothioneine is provided. Based on five synthesis genes of ergothioneine in Mycobacteroides abscessus, only an encoding sequence of each of the five genes is retained, and a gene structure of an encoding region in each gene is optimized to obtain genes related to the biosynthesis of the ergothioneine that are stably expressed in rice. These genes have sequences set forth in SEQ ID NO: 1 to SEQ ID NO: 5, and encoded proteins thereof have amino acid sequences set forth in SEQ ID NO: 6 to SEQ ID NO: 10. The gene is transferred into rice to construct a transgenic rice molecular farm to produce the ergothioneine. As a molecular farm, rice seeds do not contain alkaloids or allergens that are harmful to the human body. Moreover, biosynthesized ergothioneine shows the advantages of easy extraction and processing and of low production cost.

Abstract: A method of generating a classifier by using a small number of labeled images includes: pre-training a wide residual network by using a set of labeled data with a data amount meeting requirements, and determining portions of the pre-trained wide residual network except for a fully connected layer as a feature extractor for an image; randomly selecting, for a N-class classifier to be generated, N classes from a training set for each of a plurality of times; and for N classes selected each time: randomly selecting one or more images from each class of the N classes as training samples; extracting a feature vector from training samples of each class by using the feature extractor; inputting a total of N feature vectors extracted into a classifier generator; and sequentially performing a class information fusion and a parameter prediction for the N-class classifier by using the classifier generator.

Abstract: Disclosed is a leaping search algorithm for similar sub-sequences in character sequences and an application thereof in searching in a biological sequence database. The algorithm comprises: S0, constructing an FMD index and a lookup table for a database; S1, fetching, from the lookup table, a bi-interval of a sub-sequence with k characters in query sequences; S2, sequentially finding matching areas on the left of the k seed by using a backward search algorithm; S3, applying a forward search algorithm to an interval that has not been shrinked in step S2, to find matching areas on the right of the k seed; S4, checking whether the current detecting position is the end of the query sequence or not, and if yes, the algorithm ends, otherwise, proceeding to step S5; and S5, leaping forward w-k+1 positions from the current detecting position, and repeating steps S2 to S5. The lookup table proposed in the present invention features small memory space and a high access efficiency.
