Comparison of the Half-Lives of Transcripts of Orthologous Genes among Arabidopsis, Human, and Yeast.

(A) General features of all three mRNA decay studies, including summary statistics for each data set.

(B) The distribution of mRNA half-lives across all three species. As there were several transcripts with short mRNA half-lives in all three species, there is a scale break where the scale from 0 to 0.l is smaller (0.02).

(C) A comparison of the 627 transcripts classified as “fast”, “moderate 1,” “moderate 2,” or “slow” in yeast and/or humans compared with the respective Arabidopsis orthologous transcripts in the same categories. The number of transcripts in each category is indicated in red, and the number of genes in each category was expressed as a percentage to allow comparison of the proportion of transcripts encoding proteins in different FunCats.
