Grape anthracnose caused by (Shear) is one of the most serious fungal diseases that lead to the quality reduction and yield losses of grape ( 'Red Globe') berries. In the present study, metabolome and transcriptome analyses were conducted using grape berries in the field after infection with at 7, 10, and 13 days to identify the metabolic properties of berries. In total, 132 metabolites with significant differences and 6,877 differentially expressed genes were detected and shared by three comparisons. The analyses demonstrated that phenylpropanoid, flavonoid, stilbenoid, and nucleotide metabolisms were enriched in -infected grape berries but not amino acid metabolism. Phenolamide, terpene, and polyphenole contents also accumulated during infection. The results provided evidence of the enhancement of secondary metabolites such as resveratrol, α-viniferin, ε-viniferin, and lignins involved in plant defense. The results showed the plant defense-associated metabolic reprogramming caused by infection in grape berry and provided a global metabolic mechanism under stimulation.[Formula: see text] Copyright © 2021 The Author(s).

葡萄炭疽病是由(Shear)引起的最严重的真菌病害之一,可导致葡萄(“红地球”)浆果品质下降和产量损失。本研究采用田间感染炭疽病菌的葡萄浆果,分别在感染后 7、10 和 13 天进行代谢组和转录组分析,以鉴定浆果的代谢特性。共检测到 132 种差异代谢物和 6877 个差异表达基因,在三种比较中均有共享。分析表明,苯丙素、类黄酮、芪类和核苷酸代谢在感染的葡萄浆果中富集,但氨基酸代谢没有富集。酚酰胺、萜类和多酚含量也在炭疽病菌感染过程中积累。结果为参与植物防御的白藜芦醇、α-viniferin、ε-viniferin 和木质素等次生代谢物的增强提供了证据。结果表明,炭疽病菌感染引起的葡萄浆果中与植物防御相关的代谢重编程,并为炭疽病菌刺激下的全局代谢机制提供了证据。[公式:见正文]版权所有©2021 作者。这是一个开放获取的文章,根据 CC BY-NC-ND 4.0 国际许可证分发。
