Transcriptome indices of seedling, root and flower across 19 A. thaliana accessions. (A) The sense transcriptome age index (TAI) profile of three organs across 19 accessions. (B) The antisense transcriptome age index (TAI) profile of three organs across 19 accessions. (C) The sense transcriptome divergence index (TDI) profile of three organs across 19 accessions. (D) The antisense transcriptome divergence index (TDI) profile of three organs across 19 accessions. The standard errors of TAI and TDI, estimated by bootstrap analysis (1000 replicates), are extremely small so that they cannot be seen in (A–D), but are presented in Tables S2, 4, 6, 8 and 10. The comparisons of TAI and TDI between any two organs are significant by the Mann Whitney test, and the p-values are presented in Tables S3, 5, 7, 9 and 11. (E) Mean relative sense expression levels of evolutionarily old (PS1–PS3) and young (PS4–PS12) genes in different organs in a representative accession: Ler-0. (F) Mean relative antisense expression levels of evolutionarily old (PS1–PS3) and young (PS4–PS13) genes in different organs in Ler-0. The comparisons of relative antisense expression levels between old and young genes in different organs were performed by t test: ***means p-value < 0.001; **means p-value < 0.01; *means p-value < 0.05; no *means not significant.
