Evaluation of deficit irrigation for efficient sheep production from permanent sown pastures in a dry continental climate
Deficit irrigation can be a useful management tool to increase water productivity of forage and sheep production from pastures in water deprived areas of the world. A three year study compared sheep production from permanent sown pastures on...
Scale Effects of STATSGO and SSURGO on Flow and Water Quality Predictions
Soil information is one of the crucial inputs needed to assess the impacts of existing and alternative agricultural man- agement practices on water quality. Therefore, it is important to understand the effects of spatial scale at which soil da-...
Innovative Agriculture for Food Security Be smart, Be Systematic
If agricultural research and innovation are to deliver acceptable levels of food and nutrition security to poor communities at a global scale, a rethink is needed of how current approaches to research-for-development are planned and executed...
Capturing the Heterogeneity of the Error Variances of a Group of Genotypes in Crop Cultivar Trials
Appropriate experimental designs provide an efficient estimate of cultivar performance by allowing better control of experimental error. The standard approach assumes homogeneity of experimental error variances across plots. However, a given...
A radiation hybrid map of chromosome 1D reveals synteny conservation at a wheat speciation locus
The species cytoplasm specific (scs) genes affect nuclear-cytoplasmic interactions in interspecific hybrids. A radiation hybrid (RH) mapping population of 188 individuals was employed to refine the location of the scsae locus on Triticum...
Wheat Zapper: a flexible online tool for colinearity studies in grass genomes
In the course of evolution, the genomes of grasses have maintained an observable degree of gene order conservation. The information available for already sequenced genomes can be used to predict the gene order of nonsequenced species by means of...
Effect of protection on plant community dynamics in the Mediterranean arid zone of southern Tunisia: a case study from Bou Hedma national park
Ecosystems protected from heavy grazing impacts, such as national parks and refuges, are generally considered to sustain higher plant species diversity and better ecosystem composition and structure compared to heavily grazed areas. To evaluate...

Single Nucleotide Polymorphisms in HSP17.8 and Their Association with Agronomic Traits in Barley
Small heat shock protein 17.8 (HSP17.8) is produced abundantly in plant cells under heat and other stress conditions and may play an important role in plant tolerance to stress environments. However, HSP17.8 may be differentially expressed in...
