Transcriptome Analysis of Jujube (Ziziphus jujuba Mill.) Response to Heat Stress

Abstract

Heat stress (HS) is a common stress influencing the growth and reproduction of plant species. Jujube (Ziziphus jujuba Mill.) is an economically important tree with strong abiotic stress resistance, but the molecular mechanism of its response to HS remains elusive. In this study, we subjected seedlings of Z. jujuba cultivar “Hqing1-HR” to HS (45°C) for 0, 1, 3, 5, and 7 days, respectively, and collected the leaf samples (HR0, HR1, HR3, HR5, and HR7) accordingly. Fifteen cDNA libraries from leaves were constructed for transcriptomics assays. RNA sequencing and transcriptomics identified 1,642, 4,080, 5,160, and 2,119 differentially expressed genes (DEGs) in comparisons of HR1 vs. HR0, HR3 vs. HR0, HR5 vs. HR0, and HR7 vs. HR0, respectively. Gene ontology analyses of the DEGs from these comparisons revealed enrichment in a series of biological processes involved in stress responses, photosynthesis, and metabolism, suggesting that lowering or upregulating expression of these genes might play important roles in the response to HS. This study contributed to our understanding of the molecular mechanism of jujube response to HS and will be beneficial for developing jujube cultivars with improved heat resistance.

Surgical Management In Accidental Ingestion of Jujube Pits in Children

“…Jujubes are widely planted by Chinese over long history especially in Xinjiang province. Enriched with vitamin C, carbohydrates, organic acids, amino acids and minerals content [3],jujubes provide health bene ts such as antitumor, hepatoprotective, anti-in ammatory and neuroprotective effects [9].In traditional Chinese medicine, jujubes are believed as supplement of blood. To celebrate festivals, Chinese cook jujubes to make porridge, pastries and zongzi [10].…”

“…However, FBs as batteries, buckyballs and needles may retain and result in impaction due to special physical or chemical properties [2].Impaction of FBs develops ulcerations and perforation, or even lethal conditions. Jujubes, harvest in fall, are major agricultural crops in Xinjiang, mainland of China [3].Jujube pits, spindle-shaped objects with sharp ends, hard to pass through intestinal tract during peristalsis and discharge with feces when impaction happens. Unlike adults, children are not able to distinguish edible objects from non-edible objects and have poor swallowing coordination [4].…”

Gene Networks Involved in Plant Heat Stress Response and Tolerance

“…Transcriptome analysis of leaves at the jujube ( Ziziphus jujuba Mill.) seedling stage revealed that multiple HSPs such as HSP17, HSP18, HSP21, HSP22, HSP23, HSP26, HSP70, HSP83, HSP90, HSF30, and HSC-2 were upregulated [ 37 ]. These results suggested that Hsfs and Hsps were crucial in plants under heat stress.…”

Effects of Ziziphus Jujuba Extract Alone and Combined with Boswellia Serrata Extract on Monosodium Iodoacetate Model of Osteoarthritis in Mice

“…Based on the literature, bioactive compounds extracted from Z. jujuba have miscellaneous activities such as therapeutic effects on the nervous system, cardiovascular system, and gastrointestinal tract, improving the quality of sleep, as well as antioxidant, anti-inflammatory, and anti-cancer properties, and strong effects on blood purification ( 11 ). Furthermore, Z. jujuba can treat typhoid fever, diabetes, diarrhea, skin infections, anxiety, obesity, pharyngitis, bronchitis, anemia, and insomnia ( 12 , 13 ).…”
