Summary: Jujube is a light-demanding fruit tree, but weak light in protected cultivation facilities can degrade fruit quality. This study used a black shade net to artificially set three light intensities and found that low light suppressed sugar metabolism in jujube, mainly due to down-regulated expression of genes related to sucrose synthesis.

Summary: Jujube fruit is popular for its delicious taste, nutritional value, and medicinal properties. This study evaluated the quality of polysaccharides from jujube fruits from different areas using fingerprint profiling. The polysaccharides exhibited similar molecular weight distribution but showed differentiation in infrared spectroscopy profiles. The study also found that jujube polysaccharides can regulate gut microbiota and have potential therapeutic effects on dysentery and nervous system diseases.

Summary: The research on the growing patterns of 'Lingwu Changzao' jujube shows that fruit traits follow double 'S' growth curves, while stone traits stop increasing early in fruit growth period. This indicates a high fruit-stone ratio as a desirable quality attribute for 'Lingwu Changzao' as fresh-eating fruits.

Summary: Chinese jujube is an economically significant fruit tree in Asia with high sugar and acid concentrations. Establishing hybrid populations is challenging due to the low kernel rate. This study used cover net control as a hybridization technique to examine the role of sugar and acid components in jujube fruit. The results provide insights into the genetic predisposition and molecular mechanisms underlying sugar acids in jujube fruit.

Summary: This study utilized whole-genome resequencing and transcriptomic analysis to explore the differences between different jujube cultivars ('Linhuang No. 1' and 'Muzao'). The gene LOC107427052 encoding a nitrite reductase was identified as a key player in nitrogen metabolism in jujube through Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The insertion in the CDS region of the LOC107427052 gene could impact gene expression and further research into nitrite metabolism in jujube cultivars.

Summary: The study on 21 different cultivars of Chinese jujube revealed a variety of fatty acids, with most cultivars having high levels of total fatty acids and a significant positive correlation for unsaturated fatty acids. Chinese jujubes were found to contain a balanced content of essential omega-3 and omega-6 fatty acids, indicating high nutritional value. Additionally, fatty acid composition and content varied significantly among different cultivars, which can be classified and differentiated using principal component analysis (PCA) and linear discriminant analysis (LDA).

Summary: Different cultivars of jujube fruit show similar chemical profiles but with great variation in amounts. The cultivar 'FS' exhibits relatively higher levels of ascorbic acid, catechin, epicatechin, rutin, proanthocyanidin, and antioxidant activity, suggesting potential as a natural antioxidant. During the development stages of jujube fruit, moisture, ascorbic acid, total polyphenol, catechin, epicatechin, proanthocyanidin, and rutin contents decrease, while fructose, glucose, sucrose, cAMP, and cGMP contents increase significantly. The antioxidant activity decreases as the fruits mature, making green jujube suitable for natural antioxidants and advanced ripening stages optimal for fresh fruit and commercial processing.

Summary: This study found no significant difference in total phenolic, total flavonoids and antioxidant capacity between CD60, CD70, CD80 and FD samples. Through LC-MS/MS and HS-SPME-GC-MS analysis, it was suggested that CD60 could be an effective drying method to replace FD.

Summary: This study evaluated the potential risks associated with heavy metal intake through winter jujube consumption by analyzing the heavy metal content in 212 winter jujube samples. The results showed that more than 99.06% of the samples had safe levels of heavy metals. It was also found that adults were not at risk of carcinogenic and non-carcinogenic effects, while children may have low carcinogenic risks in certain cases.

Summary: This study reveals a unique domestication event involving genomic and metabolomic selection in jujube trees. Genomic selection was highly enriched in metabolic pathways and resulted in significant divergence of 187 metabolites due to directional selection. Specific compounds were selected to confer edible properties and the study identified significantly associated loci and regulatory genes for metabolites.
