Classification of low pH-responsive proteins (a-d) and venn diagram analysis of low pH-responsive proteins (e-f). For e, 37 or 43 identified DAPs only presented in the pH 2.5-treated C. grandis or C. sinensis leaves, respectively, and only six identified DAPs with the same accession number were shared by the two. For f, 25 or 9 identified DAPs only presented in the pH 3-treated C. grandis or C. sinensis leaves, respectively, and only two identified DAPs with the same accession number were shared by the two
