Fig. 7From: High-throughput quantification of more than 100 primary- and secondary-metabolites, and phytohormones by a single solid-phase extraction based sample preparation with analysis by UHPLC–HESI–MS/MSMetabolite levels during the development of N. attenuata seeds. Selected metabolites in the lower part of an open flower (flower base, white bars; flower without corolla, stamen, style and pedicel), in developing seed capsules (green capsule grey bars) and ripe seeds (seed black bars). The results for the other measured metabolites are shown in Additional file 1: Table S24. Error bars are ±SE (n ≥ 6). LOD limit of detection, FW fresh weightBack to article page
