Identification of QTLs for grain size and characterization of the beneficial alleles of grain size genes in large grain rice variety BL129

Genes and QTLs for Rice Grain Quality Improvement

As a major cereal crop, rice (Oryza sativa L.) is crucial to food security for at least half the world population. New varieties with high yield potential, good quality and high resistance to biotic and abiotic stresses are needed in order to meet the demand for more food arising from the rapid human population growth and concurrent decrease in arable land. Improvement of rice quality has now b...

Differential expression of GS5 regulates grain size in rice

Grain weight is a major determinant of grain yield. GS5 is a positive regulator of grain size such that grain width, filling, and weight are correlated with its expression level. Previous work suggested that polymorphisms of GS5 in the promoter region might be responsible for the variation in grain size. In this study, two single nucleotide polymorphisms (SNPs) between the wide-grain allele GS5...

Optimal Grain Size Computation for

In this paper, we present a method for overlapping communications on parallel computers for pipelined algorithms. We rst introduce a general theoretical model which leads to a generic computation scheme for the optimal packet size. Then, we use the OPIUM 3 library, which provides an easy-to-use and eecient way to compute, in the general case, this optimal packet size, on the column LU factoriza...

Effects of barley grain particle size on dairy cow performance

Grain size, size-distribution and dislocation structure

Diffraction peak profile analysis (or Line Profile Analysis, LPA) has recently been developed to such an extent that it can be applied as a powerful method for the characterization of microstructures of crystalline materials in terms of crystallite size-distribution and dislocation structures. Physically based theoretical functions and their Fourier coefficients are available for both, the size...
