This thesis consists of three manuscripts addressing separate components of barley breeding, plus an introduction and a conclusion summarizing the status of barley in the Pacific Northwest, plus the implications of the research presented in this thesis. In the first manuscript, a package written for the statistical software "R" that...
BACKGROUND: In light of the changes in precipitation and soil water availability expected with climate change,
understanding the mechanisms underlying plant responses to water deficit is essential. Toward that end we have
conducted an integrative analysis of responses to drought stress in the perennial C₄ grass and biofuel crop,

Recent work has suggested that plants differ in their relative
reliance on structural avoidance of embolism versus maintenance
of the xylem water column through dynamic traits such
as capacitance, but we still know little about how and why
species differ along this continuum. It is even less clear how
or...

Because iso- and anisohydric species differ in stomatal regulation
of the rate and magnitude of fluctuations in shoot
water potential, they may be expected to show differences in
the plasticity of their shoot water relations components, but
explicit comparisons of this nature have rarely been made.
We subjected excised shoots...

Climate change models are predicting increased frequency and severity of droughts in arid and semiarid environments, and these areas are responsible for much of the world's livestock production. Because cattle (Bos taurus) grazing can impact the abundance, distribution, and ecological function of native plant and animal communities, it is important...
