FIGURE 2.

Expression patterns of BrLAS in B. rapa. (A) Relative expression of BrLAS in different tissues (R, roots; S, stem; L, leaves; FL, flowers; Ab, axillary buds; ST, shoot tips) under normal conditions. Expression data in the shoot tips were normalized to 1. (B) Relative expression profiles of BrLAS during axillary bud development (14–42 days after germination). Expression data 21 days after germination were normalized to 1. (C–F) Expression patterns of BrLAS in response to 100 μM ABA, 250 mM NaCl, 15% (w/v) polyethylene glycol (PEG), and 100 mM H₂O₂. Total RNA was isolated from 4-week-old seedlings exposed to the various stress treatments. Expression data of the control sample were normalized to 1. Error bars show the standard error between three replicates, asterisks indicate significant differences using Student’s t-test ^∗P < 0.05, ^∗∗P < 0.01.
