Li, Shumei published the artcileEffects of different pollens on primary metabolism and lignin biosynthesis in pear, Safety of (3R,4R,5R)-6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexane-1,2,3,4,5-pentaol, the main research area is Pyrus lignin biosynthesis primary metabolism pollen; GC-MS; UPLC-MS/MS; different pollinations; lignin; metabolomics; stone cell; ‘Dangshan Su’ pear.

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 anal. of primary metabolites was achieved through untargeted metabolomics, and the quant. anal. of intermediate metabolites of lignin synthesis was undertaken using targeted metabolomics. The untargeted metabolomics anal. was performed via gas chromatog.-mass spectrometry (GC-MS). The targeted metabolomics anal. was performed using ultra-high-performance liquid chromatog.-tandem mass spectrometry (UPLC-MS/MS) under the multiple reaction monitoring (MRM) mode. The results showed that the metabolite content was significantly different between DW and DJ. Compared with that in DJ, the sugar and amino acid content in DW was higher and the fatty acid content was lower at 47 days after pollination (DAPs), and the sugar, amino acid, and fatty acid content in DWwas lower at 63 DAPs. The intermediate metabolites of lignin synthesis were analyzed using the orthogonal partial least squares discriminant anal. (OPLS-DA) model, and the differential metabolites at 47 DAPs were p-coumaric acid, ferulic acid, sinapaldehyde, coniferyl alc., and sinapyl alc. The differential significant metabolite at 63 DAPs was p-coumaric acid. At 47 DAPs and 63 DAPs, the p-coumaric acid level was significantly different, and the p-coumaric acid content was pos. correlated with lignin synthesis. The pollination pollen affects the quality of ‘Dangshan Su’ pear fruit through regulation of the sugar, amino acid, and fatty acid content; at the same time, regulating the levels of intermediate metabolites of lignin synthesis, especially the p-coumaric acid content, to affect lignin synthesis ultimately affects the stone cell content and improves the quality of the pears.
