Comparison of panicle meristem protein acetylomes of MH63, ZS97, and SY63.

(A) Boxplot showing the differences in average lysine acetylation levels of the acetylated proteins identified in panicles of MH63, ZS97, and SY63. P values were calculated by the Wilcoxon rank-sum test.

(B) Density plot showing differences in total protein acetylation levels between the hybrid and its parents.

(C) Numbers of acetylated proteins and lysine acetylation (Kac) sites with positive and negative MPH identified in SY63 panicles.

(D) Heatmap showing differences in Kac levels of histones H3 and H4 in the three genotypes. Lollipop chart (right) shows the MPH levels of the indicated Kac sites in SY63.

(E) Heatmap showing the lysine acetylation levels of ribosome proteins in MH63, ZS97, and SY63.

(F) Scatterplot showing the relationship between ribosomal protein abundance and Kac levels.
