Abstract：The omics-related research currently holds a prominent position in fruit tree studies. Collaborative investigations encompassing genomics, transcriptomics, proteomics, metabolomics, and so forth can enhance the efficiency of studies on various aspects of fruit trees. This includes exploring the origin and domestication history, understanding the mechanisms behind the formation of importantly economical traits, and identifying genes and molecular markers essential for molecular breeding practices and the molecular regulation of growth and development. The jujube (Ziziphus jujuba) is a native fruit tree that originated and was domesticated in China, and it is one of the fruit trees subjected to early whole-genome de novo sequencing. Its genome was sequenced in 2014, and since then, intensive studies through the way of multi-omics have been performed, leading to a new era in jujube research. This article systematically summarizes recent advancements in jujube genomics, transcriptomics, and metabolomics. Additionally, it outlines prospective avenues for multi-omics investigations of jujube. These insights collectively contribute to the future trajectory of jujube research, particularly in the realms of breeding and understanding the mechanisms controlling the formation of critical traits in jujube.
