Integrated analysis of metabolites and enzyme activities reveals the plasticity of central carbon metabolism in grape (Vitis vinifera cv. Cabernet Sauvignon) berries under carbon limitation Hortic. Res. (IF 7.6) Pub Date : 2024-12-28 Qian Tong, Yongjian Wang, Regina Feil, John E Lunn, Xiaobo Xu, Yi Wang, Ghislaine Hilbert-Masson, Junhua Kong, Jinliang Chen, Serge Delrot, Bertrand Beauvoit, Zhenchang Liang, Eric Gomès, Yves Gibon, Zhanwu Dai
High temperatures increase the sugar concentration of grape (Vitis vinifera L.) berries, which can negatively affect the composition and quality of wine, and global climate change is expected to exacerbate this problem. Modifying the source-to-sink ratio of grapevines by selective pruning is a potential strategy to mitigate this. To investigate the effects of low source-to-sink ratio (retaining three

Two shikimate dehydrogenases play an essential role in the biosynthesis of galloylated catechins in tea plants Hortic. Res. (IF 7.6) Pub Date : 2024-12-23 Liubin Wang, Yongxin Wang, Yueqi Wang, Liyun Wu, Mengdi He, Zhuozhuo Mao, Guanhua Liu, Kang Wei, Liyuan Wang
Tea (Camellia sinensis) is widely cultivated throughout the world for its unique flavor and health benefits. Galloylated catechins in tea plants serve as important secondary metabolites that play a pivotal role in tea taste determination and pharmacological effects. However, the genetic basis of galloylated-catechins traits remains elusive. We identified a stable and major-effect quantitative trait

Domestication history and genetic changes for the newly evolved flower color in the ornamental plant Lobularia maritima (Brassiaceae) Hortic. Res. (IF 7.6) Pub Date : 2024-12-19 Wenjie Yang, Meng Liu, Landi Feng, Pengfei Jiao, Jiebei Jiang, Li Huang, Jianquan Liu, Jordi Lopez-Pujol, Quanjun Hu
Lobularia maritima (sweet alyssum) is a popular ornamental plant that displays a range of flower colors, particularly white and purple. However, the genetic underpinning and evolutionary history of flower colors have remained unknown. To address this, we performed a de novo assembly of a chromosome-level genome for this species and conducted comparative population genomic analyses of both domestic
