DEGs relevant to the citrate cycle (TCA cycle) pathway under cold stress. Regulatory changes in the citrate cycle (TCA cycle) pathway (a), the heat map of the expression of DEGs related to citrate cycle (TCA cycle) pathway in PQ (b) and PB (c). Red boxes indicate that DEGs were regulated in PQ under cold stress, and blue boxes indicate that DEGs were regulated in PB under cold stress. Both red and blue boxes indicate that DEGs were regulated in both genotypes
