Effect of drought-hardening on various gene transcript levels in response to drought stress. Drought-hardening enhanced the expression of three antioxidant enzyme-related genes [CAT (a), APX1 (b), and GR2 (c)], two osmolyte biosynthesis-related genes [P5CS1 (d) and ADC2 (e)], one ABA signaling-related gene (SnRK2) (g), and three transcription factor-related genes [AREB1 (h), DREB2B (i), and WRKY6 (f)] in response to drought stress. HCK represents HongHuaDaJinYuan seedlings with no drought-hardening; HT1 indicates 24 h drought-hardened seedlings of HongHuaDaJinYuan; HT2 indicates 48 h drought-hardened seedlings of HongHuaDaJinYuan; HT3 indicates 72 h drought-hardened seedlings of HongHuaDaJinYuan; YCK represents Yun Yan-100 seedlings with no drought-hardening; YT1 indicates 24 h drought-hardened seedlings of Yun Yan-100; YT2 indicates 48 h drought-hardened seedlings of Yun Yan-100; YT3 indicates 72 h drought-hardened seedlings of Yun Yan-100
