Abstract: Embodiments of the present disclosure provide a distributed storage method and a distributed storage device. The method includes offline merging, by a first thread service of a distributed storage system, M small files in a file system, generating, by the first thread service, M pieces of metadata in the offline merging process, loading, by a second thread service of the distributed storage system, the M pieces of metadata into a metadata set, searching, by the second thread service, the metadata set for metadata of a first small file when the second thread service receives a first instruction, and performing, by the second thread service, the operation corresponding to the first instruction when the second thread service finds the metadata of the first small file in the metadata set.

Abstract: Provided is a rice mitochondrial sterile gene and the application thereof. A rice mitochondrial sterile gene and a coding sequence thereof are disclosed. A specific molecular marker was designed from said gene sequence and enables a rapid and effective screening and identification of D1-type cytoplasm from wild rice for breeding a new D1-type cytoplasm sterile line. A specific sequence in the mitochondria genome of D1-type cytoplasm sterile line was identified by comparative genomics. Sterility-related ORFs were identified from gene prediction and expression difference analysis. A plant transformation vector was constructed to transform maintainer line for verification and sterile function.
