Expression analysis of VaCML21v1 (a), VaCML21v2 (b), VaCML21v3 (c), and VaCML21v4 (d) splice variants 6 h, 12 h, and 24 h post-treatment in the leaves of V. amurensis exposed to control (Control, filtered water, +25 °C), water-deficit (WD, cuttings laid on a paper towel, +25 °C), high salt (0.4 M NaCl, +25 °C), osmoticum (0.4 M mannitol, +25 °C), low temperature (+10 °C and +4 °C), and high temperature (+37 °C) abiotic stress conditions. The expression of the CMLs was profiled by quantitative real-time RT-PCR. The data are presented as the mean ± SE (three independent experiments). *, **—significantly different from the Control for each time point at p ≤ 0.05 and 0.01 according to Student’s t-test.
