Using emmer wheat to discover genes involved in drought tolerance
Wheat is a major global crop, but its yields are severely compromised by drought, thus developing varieties with a higher drought tolerance is important. Emmer wheat (Triticum turgidum) is a wheat ancestor that contains more genetic diversity than cultivated varieties, so it can be used in genome wide…
Phenotypic and genomic changes during modern wheat breeding in China and the United States

Circadian regulation of the transcriptome in a complex polyploid crop (PLoS Biol)
Circadian regulation fine-tunes patterns of gene expression in plants in changing environments and has been selected for during crop domestication. Many studies have been done on circadian gene expression in Arabidopsis, but far less is known about this regulation in hexaploid bread wheat, especially…
