“…Nevertheless, other study showed the opposite results that higher activity of PPO and POD contributed to the chilling stress and lead to the formation of browning. Phornvillay, Pongprasert, Wongs‐Aree, Uthairatanakij, and Srilaong (2019) reported that the PPO and POD were involved with the phenolic oxidation with the accumulation of H 2 O 2 , finally lead to the development of browning in eggplants and okra pod. The activity of PPO/POD in CI‐susceptible fruits such as peach and lemon always exhibited similar trend during cold storage (Gao et al, 2016; Phornvillay et al., 2019).…”

The different results of antioxidant enzyme activity in response to polyamines maybe associated with the maturity and harvest time of fresh produce.…”

“…Application of exogenous putrescine and its inhibitor DL-α-(Di uoromethyl) arginine (DFMA) Exogenous putrescine and its inhibitor (DFMA) were applied to the KTRG-B49 under freezing conditions, respectively, to test the effects of putrescine on turnip freezing tolerance. The experiments were previously dscribed [50]. The 2-week-old plants were were sprayed with 1.5 mM putrescine and 0.5 mM DFMA once a day for 3 days, respectively, water was used in the control.…”

Background: In the agricultural areas of Qinghai-Tibet Plateau, temperature varies widely from day to night during the growing season, which makes the extreme temperature become one of the limiting factors of crop yield. Turnip (Brassica rapa var. rapa) is a traditional crop of Tibet grown in the Tibet Plateau, but its molecular and metabolic mechanisms of freezing tolerance are unclear. Results: Here, based on the changes in transcriptional and metabolic levels of Tibetan turnip under freezing treatment, the expression of the arginine decarboxylase gene BrrADC2.2 exhibited an accumulative pattern in accordance with putrescine content. Moreover, we demonstrated that BrrICE1.1 (Inducer of CBF Expression 1) could directly bind to the BrrADC2.2 promoter, activating BrrADC2.2 to promote the accumulation of putrescine, which was verified by RNAi and overexpression analyses for both BrrADC2.2 and BrrICE1.1 using transgenic hair root. The function of putrescine in turnip was further analyzed by exogenous application putrescine and its inhibitor DL-α-(Difluoromethyl) arginine (DFMA) under freezing tolerance. In addition, the BrrICE1.1 was found to be involved in the ICE1-CBF pathway to increase the freezing stress of turnip. Conclusions: BrrICE1.1 could bind the promoter of BrrADC2.2 or CBFs to participate in freezing tolerance of turnip by transcriptomics and targeted metabolomics analyses. This study revealed the regulatory network of the freezing tolerance process in turnip and increase our understanding of the plateau crops response to extreme environments in Tibet.
