| Summary |
For the first time, we report differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) in potato (Solanum tuberosum L.) tubers characterized by light and dark chip color after cold storage. Two potato diploid progenies derived from reciprocal crosses of parental clones possessing the T- and D-type cytoplasm were used. We recognized 48 and 15 DEGs as compared to RNA-seq data of contrasting segregants. We identified DEPs in potato tuber amyloplast and mitochondrial fractions. Seven and five DEPs were identified in the amyloplast fractions of the T – and D – type cytoplasm, respectively. Higher number of DEPs were selected from the mitochondrial fraction. The corresponding values were 97 and 105, including 39 common DEPs in the T – and D – type cytoplasm. These findings suggest that mitochondria may play a more important role than amyloplasts in response of potato tubers to cold treatment and that this influence can be different for the T – and D – type cytoplasm. However, we showed that the mt/nucDNA and pt/nucDNA ratios tend to increase for tubers characterized by dark chip color when compared with light chip color samples. Therefore, a protective effect of reducing sugars on both amyloplasts and mitochondria during low temperature treatment should be considered.
