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: An electrical receptacle connector includes an insulated housing in a metallic shell. First and second receptacle terminals are on the insulated housing. The receptacle terminals include first and second high-speed signal terminals. The metallic shell includes a receptacle cavity for receiving the insulated housing, an insertion opening being in communication with the receptacle cavity, pins at two sides of the metallic shell and outwardly extending, and an external protruding structure on a bottom surface for connecting to a circuit board. The external protruding structure forms an enclosed structure. Therefore, the seamless configuration improves the reduction to electromagnetic interference.

Abstract: A framework for performing aggregation methods on hierarchical data objects is described herein. A data aggregation request is received, the request including a tree of nodes to aggregate, an aggregation method, and a filter criteria. A configuration table is used to identify previously generated aggregation hierarchies that correspond to the received request, and a mapping of attributes of the received nodes to attributes of the previously generated aggregation hierarchies. For each node in the tree of nodes, when a corresponding node in the previously generated aggregation hierarchy is identified, attribute values from the corresponding node are used to create a node in a target aggregation hierarchy. When a corresponding node does not exist, but corresponding child nodes do exist in the previously generated aggregation hierarchy, the aggregation method is applied to the corresponding child nodes and the result is used to create a node in the target aggregation hierarchy.
