barley_001: Barley expressing a heat-stable enzyme showed highly variable expression of the enzyme, an anomalous distribution of expression in the grain, and dramatically reduced weight of individual grains.

barley_002: Transgenic barley plants over-expressing a zinc transport protein had smaller seeds and did not accumulate more zinc when grown in zinc-deficient soil.

barley_003: Difficulties were encountered when trying to express human collagen in barley.

barley_004: A group of transgenic barley plants expressing the bar selectable marker gene did not produce viable offspring.
