Joint analysis of transcriptional metabolism for flavonoid synthesis during different developmental periods in oil palm exocarp

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: March 24, 2025

To identify candidate genes for breeding oil palm varieties with high flavonoid content through molecular biotechnology, this study analyzed the metabolomes and transcriptomes of exocarp at different developmental stages using LC-MS/MS RNA-Seq techniques. The green fruiting type (FS) 95 days (FS1), 125 (FS2), 185 (FS3) after pollination served as materials. enzyme F3H, CHS, ANS, DFR were positively correlated Quercetin-3-O-sambubioside. also showed positive correlations Afzelechin, Epiafzelechin, Baimaside. In contrast, ANS negatively Hesperetin-7-O-glucoside. Additionally, CYP73A, UGT73C6, FG2-1, FG2-2 Quercetin-3-O-sambubioside, Baimaside, while CYP75A was These results suggest that play a role in promoting Quercetin-3-O-sambubioside* synthesis, further enhancing production On other hand, may inhibit Hesperetin-7-O-glucoside synthesis. Meanwhile, appear to suppress synthesis multiple flavonoids, including Quercetin-3-O-sambubioside*, Lastly, is implicated suppressing Baimaside findings provide foundation future efforts targeting flavonoid-rich varieties.

Microwave-ultrasound hybrid technology assisted extraction of pigments with antioxidant potential from red corn

Applied Food Research, Journal Year: 2023, Volume and Issue: 3(2), P. 100350 - 100350

Published: Oct. 21, 2023

Current trends in the use of new pigments natural origin have led to investigation novel technologies for obtaining them. The objectives this study were evaluate extraction process by microwave (MAE) and ultrasound (UAE) assisted techniques a treatment using simultaneously both (hybrid way) (HM-UE) from corn with different shades red (highly pigmented = RA, moderately RM poorly RB), determine color, content hydrolyzable polyphenols, condensed tannins, antioxidant potential DPPH, ABTS FRAP tests. Finally, obtained HM-UE underwent thermogravimetric analysis (TGA) characterized Fourier transform infrared spectrometry (FTIR) HPLC-MS. Results indicated that hybrid-assisted yields higher (p < 0.05) compared individual techniques, polyphenol was 15.5 % than MAE 77.3 UAE. In addition, tannin 43.6% 62.8% UAE MAE, respectively. On other hand, concentration tannins polyphenols RA showed concentrations 1.49 0.33 mg/g sample. compounds identified these derivatives belonging flavonoid family, such as Apigenin arabinoside-glucoside, 7,4′-Dihydroxyflavone, 6,8-di-C-glucoside, which their high is attributed. These results allowed visualize hybrid microwave-ultrasound technique viable option corn.

In silico prospective analysis of the medicinal plants activity on the CagA oncoprotein from Helicobacter pylori

World Journal of Clinical Oncology, Journal Year: 2024, Volume and Issue: 15(5), P. 653 - 663

Published: May 21, 2024

BACKGROUND Colonization with Helicobacter pylori (H. ) has a strong correlation gastric cancer, and the virulence factor CagA is implicated in carcinogenesis. Studies have been conducted using medicinal plants aim of eliminating pathogen; however, possibility blocking H. -induced cell differentiation to prevent onset and/or progression tumors not addressed. This type study expensive time-consuming, requiring vitro vivo tests, which can be solved bioinformatics. Therefore, prospective computational analyses were assess feasibility interaction between phenolic compounds from oncoprotein. AIM To perform prospecting interactions oncoprotein . METHODS In this silico study, structures (ligands) kaempferol, myricetin, quercetin, ponciretin (flavonoids), chlorogenic acid (phenolic acid) selected PubChem database. These chosen based on previous studies that suggested as non-drug treatments eliminate infection. The three-dimensional structure model (receptor) was obtained through molecular modeling tools I-Tasser platform, employing threading methodology. primary sequence sourced GenBank (BAK52797.1). A screening identify binding sites could potentially interact ligands, utilizing GRaSP online platform.
