Abstract: The present application discloses a semi-dominant molecular marker related to maize dwarf and an application thereof, and relates to the technical field of maize molecular breeding. The molecular marker related to the maize dwarf is caused by a non-synonymous mutation from G to A in a maize gene Zm00001d013465, and the molecular marker is a nucleotide sequence composed of the non-synonymous mutation site and its upstream and downstream bases. The present application identifies a dwarf mutant, coded as E5779, from an EMS mutation population with maize B73 as the genetic background. By genome resequencing and Mutmap mapping, it is found that the mutant is caused by the non-synonymous mutation from G to A in the gene Zm00001d013465. The molecular marker is developed based on this, and the analysis and utilization of E5779 are helpful to improve the maize plant height and density-tolerant breeding, it has an important breeding application potential.

Abstract: Systems and methods for compressing images that include a memory storing an executable code and a processor executing the code to receive a whole slide image, the whole slide image containing a plurality of image layers and metadata associated with each image layer, extract a high-resolution image layer and the corresponding metadata, wherein the high-resolution image layer includes a plurality of image tiles including informative tiles and noninformative tiles, where the informative tiles depict a region of interest of the specimen, analyze the image tiles of the extracted high-resolution image layer, determine a first tile is a noninformative tile, create an informative image layer by removing the first tile from the extracted high-resolution image layer, the informative image layer containing a plurality of informative tiles, compress the informative image layer into a single-layer whole slide image, and save the single-layer whole slide image in the memory.
