Rice by the numbers: A good grain [PDF]

open access: yesNature, 2014
Millions of people around the world rely on rice as the bulk of their daily diet. This snapshot of the crop's production, consumption and trade shows an overall surplus, but population growth in future decades may affect the situation, writes Emily Elert.

GNI-A1mediates trade-off between grain number and grain weight in tetraploid wheat [PDF]

open access: yesTheoretical and Applied Genetics, 2019
AbstractGrain yield is a highly polygenic trait determined by the number of grains per unit area, as well as by grain weight. In wheat, grain number and grain weight are usually negatively correlated. Yet, the genetic basis underlying trade-off between the two is mostly unknown. Here, we fine-mapped a grain weight QTL using wild emmer introgressions in

Allele mining for the grain number gene An-1 in rice (Oryza sativa L.)

open access: yesElectronic Journal of Plant Breeding, 2021
Rice yield has attained a plateau and hence the enhancement of grain yield is indispensable to feed the growing population, which could be achieved by the identification of superior alleles in the existing germplasm. Any variation in the pleiotropic gene,

Additional grain boundary strengthening in length-scale architectured copper with ultrafine and coarse domains [PDF]

open access: yes, 2019
The strength of polycrystals is known to increase with decreasing grain size, known as Hall-Petch effect. However, this relationship fails to predict the strength of samples with a non-uniform distribution of grain sizes.

Raised bed planting promotes grain number per spike in wheat grown after rice by improving spike differentiation and enhancing photosynthetic capacity

open access: yesJournal of Integrative Agriculture, 2023
The yield of wheat in wheat–rice rotation cropping systems in the Yangtze River Plain, China, is adversely impacted by waterlogging. A raised bed planting (RBP) pattern may reduce waterlogging and increase the wheat yield after rice cultivation by ...

Automated quantitative analysis of single and double label autoradiographs [PDF]

open access: yes, 1979
A method for the analysis of silver grain content in both single and double label autoradiographs is presented. The total grain area is calculated by counting the number of pixels at which the recorded light intensity in transmission dark field ...

Effective grain surface area in the formation of molecular hydrogen in interstellar clouds

open access: yes, 2006
In the interstellar clouds, molecular hydrogens are formed from atomic hydrogen on grain surfaces. An atomic hydrogen hops around till it finds another one with which it combines.

Formation of water and methanol in star forming molecular clouds

open access: yes, 2008
We study the formation of water and methanol in the dense cloud conditions to find the dependence of its production rate on the binding energies, reaction mechanisms, temperatures, and grain site number.

Improving detection probabilities for pests in stored grain [PDF]

open access: yes, 2010
BACKGROUND: The presence of insects in stored grains is a significant problem for grain farmers, bulk grain handlers and distributors worldwide. Inspections of bulk grain commodities is essential to detect pests and therefore to reduce the risk of their ...

The Kondo Box: A Magnetic Impurity in an Ultrasmall Metallic Grain

open access: yes, 1998
We study the Kondo effect generated by a single magnetic impurity embedded in an ultrasmall metallic grain, to be called a ``Kondo box''. We find that the Kondo resonance is strongly affected when the mean level spacing in the grain becomes larger than ...
