Correlation between cryoprotectants and selected unigenes in L. trifolii.A: Glucose; B: Trehalose; C: Glycerol. Different colors represent different treatments. Gray represents control, blue represents RCH, green represents RCHCS, red represents CS. (CK: without any temperature treatment; RCH: exposed to 5℃ for 4 h; RCHCS: acclimated at 5℃ for 4 h before exposed to discriminating temperature for 2 h; CS: exposed to discriminating temperature for 2 h without acclimation).
