We used a quantitative trait locus (QTL) approach to study the genetic basis of population differentiation in wild barley, Hordeum spontaneum. Several ecotypes are recognized in this model species, and population genetic studies and reciprocal transplant experiments have indicated the role of local adaptation in shaping population differences. We derived a mapping population from a cross betwee...

Drought is a major abiotic stress impeding the yield of cereal crops globally. Particularly in Mediterranean environments, water becomes a limiting factor during the reproductive developmental stage, causing yield losses. The wild progenitor of cultivated barley Hordeum vulgare ssp spontaneum (Hsp) is a potentially useful source of drought tolerance alleles. Wild barley introgression lines like...

In 1987, J. Daniels and B. T. Roach published an exhaustive multidisciplinary review of evidence permitting the domestication and the early evolution of sugarcane to be traced. We try here to synthesize the new data that have been produced since, and their contribution to the understanding of the global picture. It is now highly probable that sugarcane evolved from a specific lineage restricted...

The phylogenetic position of hexaploid Elymus repens within the tribe Triticeae (Poaceae) was examined using cloned sequences from the low-copy nuclear genes encoding phosphoenolpyruvate carboxylase (pepC) and beta-amylase. A previous analysis of E. repens using data from the nuclear granule-bound starch synthase I (GBSSI) gene had yielded five phylogenetically distinct gene copies, two more th...

salinity is one of the important problems in the world's agricultural land that each year millions tons of salt from the soil through crop irrigation arrive to arable lands. wheat is one of the first and most important cereal crops in the world that provide staple food for more than a third of the world's population. using modern genetic methods such as sequencing provided quickly and...
