Heat shock proteins (HSPs) play important roles in plant stress resistance, but it is not clear whether small molecular HSPs (sHSPs) are involved the cold resistance of lily flowers. In this study, we cloned LbHSP17.9 and found that its expression was up-regulated under stress. When silenced (TRV2::LbHSP17.9) using virus-induced gene silencing cut flowers, content malondialdehyde increased 4 °C treatment. The catalase (CAT) activity TRV2::LbHSP17.9 significantly lower than TRV2 first 7 days, peroxidase (POD) after days Further analysis showed transcription levels LbCu/ZnSOD, LbMnSOD LbCAT were those overexpressed petal disks, OE-LbHSP17.9 disks faded later controls at relative conductivity decreased significantly. Overexpression Arabidopsis thaliana resulted fewer injury symptoms MDA wild type Therefore, speculate can improve flowers to
