Principal component analysis (PCA) of metabolomic (A) and proteomic datasets (B) during lotus seed development. The normalized metabolite dataset (Supplementary Table S1) and NSAFs of all the identified proteins (Supplementary Table S3 sheet “Combined”) were log 10 transformed and used for PCA. The NSAFs of those proteins that identified with both in-gel and in-solution procedures were averaged for PCA.
