Preparation and Performance Evaluation of Polysaccharide-Iron Complex of .

An innovative iron supplement crucial for treating iron-deficiency anemia was developed in this study. Polysaccharide was extracted from leaves using a microwave-assisted hot water method, and subsequently, the polysaccharide-iron complex was synthesized through co-thermal synthesis with FeCl. The physicochemical properties, structure, and thermal stability of the complex were analyzed using FE-SEM, SEC-MALLS, FT-IR, XRD, and DSC techniques.

Cytological, Phytohormone, and Transcriptome Analyses Provide Insights into Persimmon Fruit Shape Formation ().

Fruit shape is an important external feature when consumers choose their preferred fruit varieties. Studying persimmon () fruit shape is beneficial to increasing its commodity value. However, research on persimmon fruit shape is still in the initial stage.

Chloroplast genome data of five species: Clarifying genome structure and phylogenetic relationships.

species have considerable ecological and economic value, however, the phylogenetic relationships among remain controversy. In this study, we sequenced and assembled the chloroplast (cp) genomes of five species: , and . We then conducted comparative genomic analyses and constructed their phylogenetic relationships.

15--Phytoene Desaturase and 15--Phytoene Synthase Can Catalyze the Synthesis of β-Carotene and Influence the Color of Apricot Pulp.

Fruit color affects its commercial value. β-carotene is the pigment that provides color for many fruits and vegetables. However, the molecular mechanism of β-carotene metabolism during apricot ripening is largely unknown.

Integrated Transcriptomics and Metabolomics Analysis Promotes the Understanding of Adventitious Root Formation in Oliver.

As a primary approach to nutrient propagation for many woody plants, cutting roots is essential for the breeding and production of Oliver. In this study, hormone level, transcriptomics, and metabolomics analyses were performed on two varieties with different adventitious root (AR) formation abilities. The higher JA level on the 0th day and the lower JA level on the 18th day promoted superior AR development.

Effects of lactic acid bacteria on antioxidant activity in vitro and aroma component of tea.

tea is a popular functional health drink in Asian countries, but its unique herbal aroma is difficult for consumers to accept. The effects of four lactic acid bacteria strains (, , and ) fermentation on the physicochemical property, antioxidant activity in vitro and aroma component of leaves were studied. Within the four strains, the sample by fermentation showed the higher concentrations of chlorogenic acid, geniposidic acid and stronger antioxidant activity in vitro.

Metabolome combined with transcriptome profiling reveals the dynamic changes in flavonoids in red and green leaves of × 'Zhonghuahongye'.

Flavonoids are secondary metabolites that have economic value and are essential for health. Poplar is a model perennial woody tree that is often used to study the regulatory mechanisms of flavonoid synthesis. We used a poplar bud mutant, the red leaf poplar variety 2025 ( 'Zhonghuahongye'), and green leaves as study materials and selected three stages of leaf color changes for evaluation.
