Genome-wide association study of rice grain width variation

Genome, 2018
Seed size is variable within many plant species, and understanding the underlying genetic factors can provide insights into mechanisms of local environmental adaptation. Here we make use of the abundant genomic and germplasm resources available for rice (Oryza sativa) to perform a large-scale genome-wide association study (GWAS) of grain width.

Structural width of low-angle grain boundaries in olivine

Physics and Chemistry of Minerals, 1983
Electron diffraction and imaging techniques have been used to examine the structure and thickness of low-angle grain boundaries in olivine. For edge-on grain boundaries, a periodic array of dislocations in a boundary gives rise to sets of periodic rods of diffracted intensity that are recorded as streaks in the diffraction pattern.

Isolation and initial characterization of GW5, a major QTL associated with rice grain width and weight [PDF]

Cell Research, 2008
Grain weight is a major determinant of crop grain yield and is controlled by naturally occurring quantitative trait loci (QTLs). We earlier identified a major QTL that controls rice grain width and weight, GW5, which was mapped to a recombination hotspot on rice chromosome 5.

On the widths of orientation gradient zones adjacent to grain boundaries

Scripta Materialia, 2009
Recrystallized commercial purity aluminum samples were deformed to true strains of 0.095 and 0.262 by uniaxial tension. Microtexture data were analyzed to quantify orientation gradients between the grain interior and the grain boundary of nearest neighbor crystallites.

Grain-boundary diffusion and boundary widths in metals and ceramics

Journal of Applied Physics, 1974
A technique is presented to calculate grain-boundary widths and grain-boundary diffusion coefficients in metals and nonmetals using grain growth, sintering, diffusion and/or creep data. High-purity metals yield boundary widths of the order of a few atomic diameters, whereas ionic materials yield ``effective boundary widths'' orders-of-magnitude wider.

A quantitative trait locus regulating rice grain width

Nature Genetics, 2007
Understanding the molecular genetic mechanisms governing agronomic traits such as grain yield is important for genetics as well as agriculture. A newly discovered quantitative trait locus, GW2, which encodes a new RING-type E3 ubiquitin ligase, has been found to regulate rice grain width.

Nonlinear grain–grain forces and the width of the solitary wave in granular chains: a numerical study

Granular Matter, 2013
Any impulse results in the formation of a solitary wave of time averaged width $$W$$ in a granular chain. If the grain–grain interaction potential $$V\sim \delta ^n ...

WL1 regulates grain width development in rice

The Plant Journal
SUMMARY Grain size is a pivotal factor that significantly influences grain yield. However, the genetic basis is mostly unknown. Here, we found that our previously identified wl1 mutant, which regulates leaf width development through the APC/C TAD1

Variation in WIDTH OF LEAF AND GRAIN contributes to grain and leaf size by controlling LARGE2 stability in rice

The Plant Cell
Abstract Grain and flag leaf size are two important agronomic traits that influence grain yield in rice (Oryza sativa). Many quantitative trait loci (QTLs) and genes that regulate these traits individually have been identified, however, few QTLs and genes that simultaneously control these two traits have been identified.

The Determination of the Grain Boundary Width of Ultrafine Grained Copper and Nickel from Electrical Resistivity Measurements

physica status solidi (a), 1997
The grain size distribution of copper and nickel processed by severe plastic deformation was studied by transmission electron microscopy. The temperature dependence of electrical resistivity in the temperature range from 20 to 300 K is presented. The tunnel model of electrical resistivity of grain boundaries is discussed.
