Transcription profiles of CsHSP17.2 gene under abiotic stress. (A) Schematic diagram of heat stress and recovery. (B) CsHSP17.2 expression levels under heat stress and recovery. R1, R2 and R3 indicate recovery from heat shock (HS) for 1, 2, and 3 h, respectively. Tea plants exposed to low temperature (4 °C) (C), 300 mM NaCl (D), 20% (w/v) PEG6000 (E) and 50 µM ABA (F). Different letters indicate significant differences (P < 0.05) between treatments and the control (0 h).
