Abstract: The present invention provides a novel gene WMS conferring wheat male sterility, its anther-specific expression promoter, and uses of the same. In wheat, a well-known gene Ms2 causing dominant male sterility has been widely applied in recurrent selection in China. A RNA-seq approach was performed to reveal the anther-specific transcriptome in a pair of Ms2 isogenic lines, ‘Lumai 15’ and ‘Lumai 15+Ms2’. As a result, a WMS gene was identified showing anther-specific expression at the early stage of meiosis and only in wheat carrying the Ms2 gene. The regulation of WMS could alter plant male fertility. The promoter of WMS was found to comprise anther-specific activity. Thus, the present invention might be used to achieve anther-specific gene expression, to develop male sterility in various plant species, to establish recurrent selection in various plant species, and to assist hybrid seed production.

Abstract: Implementations of the present specification disclose fare payment method, apparatus, and device. In the implementations of the present specification, an application can be pre-installed on a terminal device that supports HCE. When a user takes the ride, the user can move the terminal device to a vicinity of a collection device of a public transportation system. The collection device can send an HCE-based routing instruction to the terminal device, so that an operating system of the terminal device sends the routing instruction to the application based on an application identifier of the application included in the routing instruction, and then the application establishes an NFC connection with the collection device in response to the routing instruction.

Abstract: Circuits, methods, and apparatus that may provide power supply voltages in a safe and reliable manner that meets safety and regulatory concerns and does not exceed physical limitations of cables and other circuits and components used to provide the power supply voltages. One example may provide a cable having a sufficient number of conductors to provide power without exceeding a maximum current density for the conductors. Another example may provide a cable having more than the sufficient number of conductors in order to provide an amount of redundancy. Current sense circuits may be included for one or more conductors. When an excess current is sensed, a power source in the power supply may be shut down, the power source may be disconnected from one or more conductors, or both events may occur.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a currency type switching method are provided. One of the methods includes: determining a transaction currency type and a transaction channel of a transaction; determining whether the transaction channel supports the transaction currency type; and in response to a determination that the transaction channel does not support the transaction currency type, changing the transaction currency type to a designated currency type supported by the transaction channel. By automatically changing the transaction currency type to a supported currency type, this method eliminates the cumbersome processes a user otherwise needs to go through to manually change the transaction currency type, hence it enhances the user experiences in an online transaction.
