The effect of maturity (days post-anthesis, DPA) on the accumulation of representative hordein family-specific peptides following chymotrypsin cleavage. The mean multiple reaction monitoring (MRM) peak area ± SE (n = 3) from 5 μg extracted protein is shown for peptides mapping to: (A) B1-hordeins P06470-C1 (Inline graphic, right y-axis), P06470-C2 (Inline graphic, left y-axis), and P06470-C3 (Inline graphic, right y-axis); (B): B3-hordeins I6SW30-C1 (Inline graphic, left y-axis), I6SJ26-C1 Inline graphic, right y-axis), I6SJ26-C2 (Inline graphic, left y-axis); (C) C-hordeins Q40053-C1 (Inline graphic), Q40053-C3 (Inline graphic) and Q41210-C4 (Inline graphic); (D) D-hordein I6TRS8-C1 (Inline graphic), I6TRS8-C5 (Inline graphic) and I6TRS8-C6 (Inline graphic); (E) γ1-hordein TC131355-C1 (Inline graphic), γ1-hordein I6TMV6-C1 (Inline graphic); (F) γ3-hordein I6TEV2-C1 (Inline graphic, left y-axis), γ3 I6TEV2-C2 (Inline graphic, right y-axis), and γ3 I6TEV2-C3 (Inline graphic, right y-axis). The sequence of the proteins and peptide markers are shown in Supplementary Table S4. Where the SE is less than symbol size it is not shown. For clarity, symbols of significance are not shown but where points differ by 2 × SE they are significantly different. Detailed statistical comparisons are shown in Supplementary Figures.
