Genes associated with different biological processes regulated by low temperature in Zhonghua 11.

“Up_4” or “Up_10” indicated the up-regulated genes by low temperature at 4 or 10 days after fertilization; “Do_4” or “Do_10” indicated the down-regulated genes by low temperature at 4 or 10 days after fertilization. Chi-square test was performed to test the enrichment of each GO term. The data indicates −log10 (P value). “-” indicated the corresponding genes were not enriched for the GO term.
