Transcriptome Analyses Reveal the Mechanism of Changes in the Sugar Constituents of Jujube Fruits under Saline–Alkali Stress

Saline–alkali stress is an important environmental factor affecting the growth and development of plants. Plants affected by saline–alkali can mitigate damage regulating content osmoregulatory substances such as soluble sugars. Elucidating regulatory mechanism changes in sugar fractions jujube fruits under crucial for fruit industry saline areas. In this study, we investigated effects on contents subjecting trees to low- high-saline–alkali treatments. The result showed that low increased each component total sugar, whereas high suppressed their contents. early developmental stage, mainly accumulated fructose glucose, late it sucrose. We screened various genes, namely trehalose 6-phosphate phosphatase gene (LOC107418410), α-amylase (LOC107428855), α-glucosidase (LOC107418468), sucrose synthase (LOC107416188), β-amylase (LOC107430415, LOC107406235), all which were highly correlated with stress, indicating starch metabolic pathways are key accumulation response stress. To summarize, study provides a system-level perspective dynamic transcriptional regulation Additionally, preliminarily differentially expressed genes affect providing theoretical basis scientific quality.
