It’s hard to go anywhere without a map – especially into the deep and complex world of genetics. Now, Kansas State University researcher Bikram Gill and an international team of researchers have developed a physical map of wheat’s wild ancestor, Aegilops tauschii, commonly called goatgrass, as they take the first huge step toward sequencing the wheat genome – a complete look at wheat’s genetic matter.
A physical map of a genome shows the physical locations of genes and other DNA sequences of interest. Scientists use them to identify and isolate genes that are responsible for different traits, such as disease resistance and days to maturity.
The research was published in the April 22 edition of the Proceedings of the National Academy of Sciences (PNAS) http://www.pnas.org/content/early/2013/04/18/1219082110.full.pdf+html.
