Fig. 1From: Chilling-induced DNA Demethylation is associated with the cold tolerance of Hevea brasiliensisChilling treatment induced the expression of the HbICE and HbCBF genes of H. brasiliensis. Seedlings of H. brasiliensis were treated at 19 °C (a and c) or 4 °C (b and d). Samples were collected at the time points indicated. The expression levels of HbICE (a and b) and HbCBF (c and d) genes were analysed by qRT-PCR. Values are presented as the mean standard error of three independent biological replicates. Different letters indicate significant differences (P < 0.05) according to one-way analysis of varianceBack to article page
