The EP- and LP-preferred expression patterns were consistent even during the winter dormancy period. a, b, and c Pearson correlations of expression differences among needles in mid-winter and spring. Scatter plots show 512 genes expressed (mean TPM > 1) in needles in winter. N, needles; EN and LN, needles from EPs and LPs, respectively. The numerical order indicates the different sampling times. ENw and LNw indicate needles sampled in the winter. d PCA based on the expression data of 640 genes. Each symbol represents a sample of individuals; a total of 84 samples are shown in the plot. All of the male cone and needle samples collected either in winter or in spring could be divided into EP (top) and LP (bottom) groups
