Figure 4. Semi-quantitative RT-PCR of PfHSP17.2 expression in P. forrestii. (a) Heat treatment, time course induction of PfHSP17.2 by heat in P. forrestii; (b) cold treatment, time course induction of PfHSP17.2 by cold in P. forrestii; (c) Transcript levels of PfHSP17.2 in leaves under different treatments for 3 h. CK, no treatment as control (plants only irrigated with half-strength MS salt solution); (d) expression of PfHSP17.2 in different organs after incubation at 42 °C for 2 h; (e) semi-quantitative RT-PCR analysis in developing seeds and germinating seeds (f), respectively. DAP, days after pollination. HAI, hours after imbibition. YL, young leaves (5 d from emergence). OL, old leaves (two weeks from emergence). F, flower. P, petiole. R, root.
