Figure 2.
Physiological, soil and normalized expression variability across experiments and treatments. A, Coefficients of variation (cv = sd / mean) were calculated for each physiological and gene expression phenotype. Raw cv for each physiological phenotype is plotted. B, To understand the relationships between Ψsoil and soil volumetric water content, we conducted soil moisture release curves for the greenhouse potting soil where a soil sample was progressively dried and volumetric water content and Ψsoil were repeatedly measured; the range of observations for each treatment are presented by the marginal line segments. C, Mean (± se) cv across all expression traits is plotted. The experiments are abbreviated as shelter (shel), greenhouse (gh), and cylinder (cyl).
