This Week in PNAS

In the early, online edition of the Proceedings of the National Academy of Sciences, a team from the US and the UK describe variation patterns in thousands of tetraploid or hexaploid wheat plant lines. Using a custom NimbleGen array designed to capture more than 82,500 wheat gene transcripts, the researchers sequenced nearly 287,000 protein-coding exon sequences from 1,535 mutagenized tetraploid wheat lines and 1,200 mutagenized versions of a hexaploid wheat variety.
