Figure 7.

Response of a subset of three lines of B. distachyon in root and shoot partitioning to well-watered and drought conditions (experiment 4; for all of the lines in this experiment, see Supplemental Fig. S5; for detailed conditions, see Supplemental Table S1). A, Shoot dry weight. B, Total root length. C, Specific root length. D, Primary seminal root length. E, Root length partitioning in well-watered condition. F, Root length partitioning in drought condition. Error bars represent sems (n = 4). *, Significant differences between the treatments in A to D. Similar letters (a–c) in E and F show groups with no significant difference (P < 0.05): PSR (blue), CNR (red), and LNR (green).
