摘要:

为探究浦江桃形李黑心病病因,以成熟期浦江桃形李黑心病果实(XMB)和正常果实(XMG)为研究对象,采用非靶向代谢组学法,分析比较了XMB与XMG的代谢物差异。经二级质谱鉴定,共获得90个差异代谢物,包括植物抗毒素6-甲氧基蜜林在内的27个代谢物相对含量上调,63个代谢物相对含量下调。KEGG富集分析表明,苯丙烷代谢途径被激活。结果表明浦江桃形李黑心病可能是一种由病原菌侵染引起的病理性病害,本研究为该病害防治提供了重要参考。

Abstract:

To investigate the etiology of internal browning of peach-shaped plum in Pujiang,mature fruits with internal browning(XMB)and normal fruits(XMG)were used as research objects. Non-targeted metabolomics was applied to analyze and compare the metabolite profiles between XMB and XMG. A total of 90 differential metabolites were identified by secondary mass spectrometry. Twenty-seven metabolites,including the plant antitoxin 6-methoxymellein,showed upregulation in relative content,while sixty-three metabolites showed downregulation in relative content. KEGG enrichment analysis indicated that the phenylpropanoid metabolic pathway was activated. The results suggest that internal browning of peach-shaped plum in Pujiang is likely a pathological disorder induced by pathogen infection,providing an important reference for disease control.

Key words: peach-shaped plum in Pujiang, internal browning, metabolomics, 6-methoxymylin, phenylpropanoid metabolic pathway
