Peptides and proteins were identified and quantified using label-free proteomics

ID ≥ 2, peptides or proteins identified in at least two replicates; percentage quantified, percentage of peptides or proteins quantified from the identified ones in at least two replicates. Different lowercase letters indicate significant difference at 0.05 level. Data are mean ± SD (n = 3)
