Fig. 2

Number of differentially expressed genes of three species at 0 °C, 4 °C, 14 °C, and 28 °C relative to control temperature (25 °C). In general, the numbers of differentially expressed genes were low at the first timepoint but increased in the later timepoints. Blue bar represents Le. gelidum, red bar Lc. piscium, and green bar P. oligofermentans
