Expression profiles of GhWRKY42 under different abiotic stresses. Ten-day-old cotton seedlings were exposed to (a) 100 μM MeJA, (b) 200 μM ABA, (c) 15% PEG6000 and (d) 200 mM NaCl. Samples were collected at 0 h, 2 h, 4 h, 6 h, 8 h and 12 h. Total RNA was extracted for qRT-PCR. GhActin served as the reference gene. The bars represent the means ± standard errors (SEs) from three independent experiments
