  • a *, P ≤ 0.05 (one-way ANOVA).

  • b Values represent protein abundance ratios (log2) normalized to the ground control.

  • c CCC, cell cycle control, cell division, chromosome partitioning, transport, and catabolism; UN, function unknown; STM, signal transduction mechanisms; DM, defense mechanism; IIT, inorganic ion transport and metabolism.
