Identification of differentially expressed genes (DEGs) under cold treatment in <i>V. amurensis</i> and <i>V. vinifera</i> cv. Muscat of Hamburg.

<p>TPM (tags per million clean tags) were used to represent the expression levels of genes in non-cold treatment (NCT) and cold-treatment (CT) libraries in two grape varieties. Two parameters, “FDR <0.001” and “|log2 Ratio| ≥ 1” were used as the threshold to evaluate the significance of gene expression difference. Red and green dots represent the up- or down-regulated transcripts, respectively, during cold treatment in <i>V. amurensis</i> and Muscat of Hamburg. Black dots indicate transcripts without significant changes under cold stress.
