Integrated transcriptomic and metabolomic analyses reveal key genes controlling flavonoid biosynthesis in Citrus grandis 'Tomentosa' fruits.

As a well-recognized traditional Chinese medicine (TCM), immature fruits of Citrus grandis 'Tomentosa' (CGT) serve to cure chronic cough in humans. Specialized metabolites including flavonoids may have contribute to this curing effect. Knowledge about the molecular mechanisms underlying flavonoid biosynthesis in 'Tomentosa' fruits will, therefore, support the breeding of varieties with improved medicinal properties.

Arsenic inhibits citric acid accumulation via downregulating vacuolar proton pump gene expression in citrus fruits.

Citric acid content is a critical quality determinant in citrus (Citrus spp.) fruits. Although arsenic (As) can effectively reduce citric acid content to improve citrus fruit quality, it can have adverse environmental effects.

Comparative investigation of bioflavonoid electrocatalysis in 1D, 2D, and 3D carbon nanomaterials for simultaneous detection of naringin and hesperidin in fruits.

Electrocatalysis of bioflavonoids in carbon nanomaterials plays an important role in electrochemical sensors for the detection of their content in fruits. In this study, three types of carbon nanomaterials with 1D, 2D, and 3D structures, namely carbon nanotubes (CNTs), graphene oxide (GO), and Ketjen black (KB), were modified onto glassy carbon electrodes for the electrocatalysis of hesperidin and naringin, which are two important bioflavonoids in fruits. As a result, the CNT-modified electrodes showed the highest electrocatalytic activity for both hesperidin and naringin compared to GO and KB.

Chemical elucidation and rheological properties of a pectic polysaccharide extracted from Citrus medica L. fruit residues by gradient ethanol precipitation.

Citron (Citrus. medica L.) fruits are commonly utilized in the production of essential oil, therefore, the fruits residues turn out to be industrial byproducts.

A comparative UPLC-Q-Orbitrap-MS untargeted metabolomics investigation of different parts of (Lour.) Skeels.

In this study, the non-targeted large-scale plant metabolomics (UPLC-Q-Orbitrap-MS) was performed for the comparison of chemical profiling of the leaves, barks, flowers, peels, pulps, and seeds of (Lour.) Skeels (called "wampee"). A total of 364 metabolites were identified, and 62 potential biomarkers were selected by the multivariate statistical analysis.

Contribution of anthocyanin pathways to fruit flesh coloration in pitayas.

Background: Color formation in Hylocereus spp. (pitayas) has been ascribed to the accumulation of betalains. However, several studies have reported the presence of anthocyanins in pitaya fruit and their potential role in color formation has not yet been explored.

Genome-Wide Identification and Characterization of the NAC Transcription Factor Family in and Expression Analysis during Fruit Ripening.

Banana (, AAA group) is a representative climacteric fruit with essential nutrients and pleasant flavors. Control of its ripening determines both the fruit quality and the shelf life. NAC (NAM, ATAF, CUC2) proteins, as one of the largest superfamilies of transcription factors, play crucial roles in various functions, especially developmental processes.

Activation of RAW264.7 macrophages by an acidic polysaccharide derived from Citrus grandis 'Tomentosa'.

Citrus grandis 'Tomentosa' which is a special Citrus cultivar, has been employed as cough suppressant and expectorant in traditional Chinese medicine for thousands of years. The aim of this study is to investigate the immunomodulatory role of an acidic polysaccharide (designated as CGTP-AP) purified from C. grandis 'Tomentosa'.

Structural elucidation of an acidic polysaccharide from Citrus grandis 'Tomentosa' and its anti-proliferative effects on LOVO and SW620 cells.

Citrus grandis 'Tomentosa' (CGT) which is a region-famous medicinal and edible plant contains plentiful bioactive polysaccharides, however, its chemical structures and specific bioactivities still need to be further explored. In the present study, an acidic polysaccharide (CGTP-AP) was extracted and purified from the pulps of CGT. The structure elucidation and anti-cancer activity of CGTP-AP were investigated.

Plant tannin immobilized FeO@SiO microspheres: A novel and green magnetic bio-sorbent with superior adsorption capacities for gold and palladium.

In this paper, a new core-shell nanostructured magnetic bio-based composite was prepared by immobilizing persimmon tannin (PT) onto FeO@SiO microspheres, and the as designed FeO@SiO@PT was utilized for adsorptive recovery of Au(III) and Pd(II). The preparation, morphology, composition and magnetic property of FeO@SiO@PT were characterized. Adsorption parameters of FeO@SiO@PT towards Au(III) and Pd(II) including initial pH, reaction time, initial concentration of metal ions, effect of acidity and interference of coexisting metal ions were investigated.

Selective adsorption and recovery of Au(III) from three kinds of acidic systems by persimmon residual based bio-sorbent: a method for gold recycling from e-wastes.

A low cost bio-sorbent, named "PPF resin", was prepared by crosslinking the persimmon residual with formaldehyde. The adsorption behavior of PPF resin towards Au(III) from varied HCl and HNO3 concentration solutions was studied. PPF resin could adsorb almost complete Au(III) from high acidic systems.
