Characterization of the CsCENH3 protein and centromeric DNA profiles reveal the structures of centromeres in cucumber Hortic. Res. (IF 7.6) Pub Date : 2024-05-07 Yi Wang, Fang Zhou, Yangang Li, Xiaqing Yu, Yuhui Wang, Qinzheng Zhao, Xianbo Feng, Jinfeng Chen, Qunfeng Lou
Centromeres in eukaryotes mediate the accurate segregation of chromosomes during cell division. They serve as essential functional units of chromosomes and play a core role in the process of genome evolution. Centromeres are composed of satellite repeats and highly repetitive centromeric retrotransposons (CRs), which vary greatly even among closely related species. Cucumber (Cucumis sativus) is a globally

CRISPR/Cas9 genome editing of potato StDMR6-1 results in plants less affected by different stress conditions Hortic. Res. (IF 7.6) Pub Date : 2024-05-06 Milla Karlsson, Nam Phuong Kieu, Marit Lenman, Salla Marttila, Svante Resjö, Muhammad Awais Zahid, Erik Andreasson
Potato is the third most important food crop, but cultivation is challenged by numerous diseases and adverse abiotic conditions. To combat diseases, frequent fungicide application is common. Knocking out susceptibility genes by genome editing could be a durable option to increase resistance. DMR6 has been described as a susceptibility gene in several crops, based on data that indicates increased resistance

Evolutionarily conserved 12-oxophytodienoate reductase trans-lncRNA pair affects disease resistance in tea (Camellia sinensis) via the Jasmonic acid signaling pathway Hortic. Res. (IF 7.6) Pub Date : 2024-05-06 Ting Jiang, Tianming Jiao, Yingbang Hu, Tongtong Li, Cheng Liu, Yajun Liu, Xiaolan Jiang, Tao Xia, Li-Ping Gao
Long non-coding RNAs (lncRNAs) have gathered significant attention due to their pivotal role in plant growth, development, and biotic and abiotic stress resistance. Despite this, there remains little understanding regarding the functions of lncRNA in these domains in the tea plant (Camellia sinensis, C. sinensis), mainly attributable to the insufficiencies in gene manipulation techniques for tea plants

Jasmonate enhances cold acclimation in jojoba by promoting flavonol synthesis Hortic. Res. (IF 7.6) Pub Date : 2024-05-03 Lamei Zheng, Bojing Li, Genfa Zhang, Yijun Zhou, Fei Gao
Jojoba is an industrial oil crop planted in tropical arid areas, and its low-temperature sensitivity prevents its introduction into temperate areas. Studying the molecular mechanisms associated with cold acclimation in jojoba is advantageous for developing breeds with enhanced cold tolerance. In this study, metabolomic analysis revealed that various flavonols accumulate in jojoba during cold acclimation

Stem cell homeostasis is pivotal for continuous and programmed formation of organs in plants. The precise control of meristem proliferation is mediated by the evolutionarily conserved signaling that encompasses complex interactions among multiple peptide ligands and their receptor-like kinases. Here, we identified compensation mechanisms involving the CLAVATA1 (CLV1) receptor and its paralogs, BARELY

Four novel Cit7GlcTs functional in flavonoid 7-O-glucoside biosynthesis are vital to flavonoid biosynthesis shunting in citrus Hortic. Res. (IF 7.6) Pub Date : 2024-04-25 Ziyu Yuan, Gu Li, Huixian Zhang, Zhaoxin Peng, Wenyu Ding, Huan Wen, Hanxin Zhou, Jiwu Zeng, Jiajing Chen, Juan Xu
Citrus fruits have abundant flavonoid glycosides (FGs), an important class of natural functional and flavor components. However, there have been few reports about the modification of UDP-glycosyltransferases (UGTs) on flavonoids in citrus. Notably, in flavonoid biosynthesis, 7-O-glucosylation is the initial and essential step of glycosylation prior to the synthesis of flavanone disaccharides, the most
