  1. *The modification site, type, and relative abundance (%) of each PTM are expressed as the mean ± standard error (n = 5) without missing values. Data were analyzed using the least squares means method and Kruskal–Wallis test.
  2. a,bSuperscripts indicate a difference between groups within the same PTMs (P < 0.05).
