The evolution of wheat from wild grasses demonstrates the dramatic effect of both natural and directed evolution on the structure of a crop plant and the chemical makeup of the product harvested from it. Evolution of wild wheat and barley and crop improvement: Studies at the Institute of Evolution. A wealth of data on the genomic structure of cultivated wheats has accumulated after almost a century of research, beginning with the pioneering genetic experiments of NilssonEhle (1909) and the cytological studies of Sakamura (1918) and Sax (1918).

For (1), one manuscript, direc-ted by co-PI Dvořák and postdoc E. Akhunov, has been submitted and a second is in preparation. Poaceae (/ p oʊ ˈ eɪ s i aɪ /) or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses.It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture.
