Morphological characteristics and TPM (the Transcripts Per Million) values of chloroplast genes in O. vulgatum. (a) Habitat and morphological characteristics of O. vulgatum (photos were taken by ourselves). (b) Heat map of Spearman’s rank correlation coefficient for all genes’ TPM values of three biological repeats (the numbers on the upper triangular are correlation coefficients; the TPM1, TPM2, and TPM3 are the TPM value of three repeats, the 'TPM' is the mean value of biological repeats, the same as below; * represents significant at the 0.05 level). (c) TPM values of highly expressed genes in chloroplast
