Abstract: Genes associated with nitrogen utilization efficiency (NUE) in plants are provided. The gene VRN1N was identified as TaNUE1 in chromosome 5A of the wheat cultivar Jagger and is encompassed by quantitative trait locus Qnue.osu-5A. VRN1N is regulated by nitrogen is associated with enhanced NUE by plants which contain the gene. In addition, the gene ANR1 from wheat cultivar Jagger has also been identified as involved in nitrogen metabolism. Methods for genetically engineering plants to contain and express one or both of VRN1N and ANR1 are also provided, as are genetically modified plants that have been transformed with one or both of the genes, and plants that have been bred conventionally and selected for the presence of one or both genes.

Abstract: A vertex data compression method includes: collecting a plurality of vertices as a vertex block; extracting at least one data unit array from the vertex block, wherein each data unit array is composed of data units selected from vertex components of the vertices respectively, the data units correspond to a same channel, and each data unit is smaller than one byte; and for each data unit array, checking the data units of the data unit array to select a compression algorithm, and compressing the data units of the data unit array according to the selected compression algorithm.
