The responses of floridoside and isofloridoside in Neoporphyra haitanensis to cold stress. A Floridoside and isofloridoside level changes. **P < 0.01, compared to 20 °C group; ##P < 0.01, compared to Day 0 group. B The expression of putative floridoside-6-phosphate synthases genes. Thalli were cultured at − 4, 4, 10 and 20 °C for 1 day (T-4D1, T4D1, T10D1 and T20D1). FPKM values of the genes in different groups were used to construct the heatmap after a z-score normalization (n = 3)
