Correlation between unsaturated rate of fatty acid and expression of related unigene in L. trifolii. 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).
