Effects of Different Pollens on Primary Metabolism and Lignin Biosynthesis in Pear.

ABSTRACT: To investigate the effect of pollination on the fruit quality of 'Dangshan Su' pear, 'Dangshan Su' was fertilized by the pollen of 'Wonhwang' (Pyrus pyrifolia Nakai.) (DW) and 'Jingbaili' (Pyrus ussuriensis Maxim.) (DJ). The analysis of primary metabolites was achieved through untargeted metabolomics, and the quantitative analysis of intermediate metabolites of lignin synthesis was undertaken using targeted metabolomics. The untargeted metabolomics analysis was performed via gas chromatography-mass spectrometry (GC-MS). The targeted metabolomics analysis was performed using ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) under the multiple reaction monitoring (MRM) mode. The results showed that the metabolite content was significantly differ
