The global m⁶A levels in total RNA and mRNA during tomato fruit expansion stages. A, Photographs of the fruits at different expansion stages of tomato. The levels of m⁶A in (B) total RNA and (C) mRNA at different stages of fruit expansion are shown in (A). Data represent means ± standard deviation of three biological replicates (n = 4), and asterisks indicate significant differences (Student’s t test, *P < 0.05, **P < 0.01, ***P < 0.001). ns, not significant. PC, positive control. NC, negative control.
