Expression of LreEF1As in Lilium regale leaves under cucumber mosaic virus (CMV) inoculation, abiotic stresses, and hormone treatments. Quantitative real-time polymerase chain reaction (PCR) analysis of LreEF1A1–4 transcript abundances in response to CMV (A), 200 mM NaCl (B), dehydration (C), low temperature (4 °C, D), high temperature (37 °C, E), 8 μL·L^–1 ethylene (Eth, F), 100 μM salicylic acid (SA, G), 40 μM gibberellic acid (GA₃, H), and 40 μM abscisic acid (ABA, I) at indicated time points. L. regale plantlets at the two-leaf stage were infected with CMV, or treated with various abiotic stressors and plant growth regulators. Transcript levels were standardized to LrGAPDH. Error bars represent standard error (SE) of the mean from three independent biological replicates. Asterisks indicate statistical significance as determined by Student’s t-test at p < 0.05.
