List of poplar leaf proteins from the second sampling, identified by MS/MS analysis, including average ratio of protein abundance.

a) In brackets, corresponding spot number in the other samplings (manually checked and confirmed by MS/MS analysis).b) Number of identified peptides and sequence coverage.Graphical representation of the average ratios of the protein abundance is shown in Table S2 of the supplementary materials.

a) 括号内标注其余采样中的对应位点编号（经手动核验并通过MS/MS分析验证）。b) 已鉴定肽段的数量与序列覆盖率。蛋白质丰度平均比值的可视化呈现详见补充材料中的表S2。
