In contrast to the general belief that 4- and 5-sided grains transform to 3-sided before their disappearance in 2-D grain growth, we found ample evidence that 4-sided and 5-sided grains may directly evolve to a region of disordered material, whose size is on the order of the grain boundary thickness and whose boundaries with neighbours are not well defined, and then disappear.
When analyzing QTLs for grain width, we found that the QTL with largest effect was mapped to the bin of about 123 kb in length containing the GW5/qSW5 locus on chromosome 5.
The differences in IR64, due to differences in water availability, highlight how water stress not only affects grain yield, but also the metabolites present in the grains, and we found this to be reflected in the responses of the sensory panel.
In addition, for intermediate initial grain misorientations, we find a repeating faceting defaceting transition during grain shrinkage and a different relationship between the grain area and time, which suggests a different grain growth mechanism than that for small and large misorientations.
Consistent with our earlier simulations of grain-boundary diffusion creep, albeit in the absence of grain growth, we find that initially, i.e. prior to the onset of significant grain growth, the deformation proceeds via the mechanism of Coble creep.
Furthermore, by analysing the full set of candidate structures generated by simulated annealing for the two grain boundaries, we find that the number of fivefold coordinated Al atoms tends to increase with grain boundary energy, which we can also correlate with the behaviour of the electronic density of states.
PSY3 homoeologous copies showed a variable pattern of expression during the first stage of cellular division during early grain development and we found PSY-A3 and PSY-D3 most expressed in leaves and PSY-D3 in roots.
Where the sedimentary sequence is characterized by gradational changes in composition and grain size, we find that deformation structures are best characterized by patterns of distributed strain.
By applying a model supposing potential fluctuations at the grain boundaries we find that the potential barrier height decreases from 0.269 eV down to 0.112 eV and the homogeneity coefficient, which describes the homogeneity of films, decreases from 4.41 to 2.91 with increases in Sn content from 1 at.% up to 7 at.%.
To suppress the major allergen levels in rice grains, we first found a mutant in the Koshihikari background that lacked the 26 kDa allergen (GbN-1).
