Chinese jujube (Ziziphus jujuba), an economically important species in the Rhamnaceae family, is a popular fruit tree in Asia. Here, we surveyed and characterized simple sequence repeats (SSRs) in the jujube genome. A total of 436,676 SSR loci were identified, with an average distance of 0.93 Kb between the loci. A large proportion of the SSRs included mononucleotide, dinucleotide and trinucleo...

Jujube (Ziziphus jujuba Mill.) belongs to the Rhamnaceae family and is a popular fruit tree species with immense economic and nutritional value. Here, we report a draft genome of the dry jujube cultivar 'Junzao' and the genome resequencing of 31 geographically diverse accessions of cultivated and wild jujubes (Ziziphus jujuba var. spinosa). Comparative analysis revealed that the genome of 'Dong...

Rainfall and temperature are the primary limiting factors for optimum quality and yield of cultivated jujube (Ziziphus jujuba Mill.). Adaptation to arid and cool environments has been and remains an important goal of many jujube improvement programs. This study summarized the survey results of 116 Chinese jujube varieties grown at 33 sites in China. The objective was to identify the environment...

Jujube is a common fruit in Chinese diet, jujube pit is sharp but has rarely been reported to cause digestive tract perforation. Here we presented a rare case of sigmoid colon perforation by a jujube pit in an 88 year-old toothless woman. The evidence of peritoneal irritation was acquired by physical examination and CT scan. Then perforation peritonitis was diagnosed, and emergency operation wa...

Purpose: To develop a simple and precise method for the determination of the levels of both essential and toxic elements in jujube collected from different locations in China. Methods: Dried jujube fruits collected were digested by optimized microwave procedure. Inductively coupled plasma atomic emission spectrometry was employed to evaluate essential elements, viz, calcium, magnesium, manganes...

Fresh jujube (Ziziphus jujube) is rich in vitamin C, which is an important quality index and generally decreases with storage time. The aim of this study was to build kinetic models for determining the vitamin C content, thus predicting the quality characteristics and shelf life of fresh jujube. The quality changes of the jujube stored at room temperature (20 °C) were analyzed using near-infrar...

The aim of this study was to observe the effects of jujube on learning and memory in ovariectomized rats. The effects of jujube on learning and memory in ovariectomized rats were observed using the Morris water maze method. The serum follicle-stimulating hormone (FSH), estrogen and luteinizing hormone (LH) levels, and the brain nitric oxide synthase (NOS) and acetylcholinesterase (AChE) levels ...

Increasing demand for more jujube (Ziziphus jujube Mill.) production requires understanding the specific fertilization needs of jujube trees. This study was conducted to compare fruit yields, phenolic profiles and antioxidant activity of jujube in response to different fertilizers. Application of organic fertilizer appeared to enhance the phenolics and antioxidant activity accumulation of jujub...
