TSN Is a Positive Regulator of mRNA Decapping during Heat Stress.

(A) Quantification and relative abundance of uncapped mRNAs in Col, Ler, and tsn1 tsn2 plants grown under control and heat stress conditions. The percentages of mRNAs in each category were calculated relative to the total number of mRNAs.

(B) GO analysis (term “molecular function”) of TSN-dependent mRNA decapping. The chart displays the ratios between the percentage of mRNAs belonging to a particular GO term that show significant depletion in uncapped form in tsn1 tsn2 and the percentage of mRNAs belonging to the same GO term in the total mRNA population under heat stress. The horizontal red axis indicates a ratio value of 1. The overrepresented category is marked with an asterisk (P < 0.05, Fisher’s exact test).
