Defense Priming in Nicotiana tabacum Accelerates and Amplifies ‘New’ C/N Fluxes in Key Amino Acid Biosynthetic Pathways

open access: yesPlants, 2020
In the struggle to survive herbivory by leaf-feeding insects, plants employ multiple strategies to defend themselves. One mechanism by which plants increase resistance is by intensifying their responsiveness in the production of certain defense agents to

Serum Metabolomic Profiling for Acute Myocardial Infarction Based on Nuclear Magnetic Resonance Spectroscopy

open access: yesNMR in Biomedicine, Volume 39, Issue 9, September 2026.
1H NMR–based serum metabolomics was employed to identify AMI differential biomarkers and associated metabolic pathways. A diagnostic model evaluated via ROC analysis demonstrated robust performance of these biomarkers, thereby providing novel insights into the pathophysiological mechanisms underlying AMI. ABSTRACT Acute myocardial infarction (AMI) is a

Rational Engineering of Chorismate-Related Pathways in Saccharomyces cerevisiae for Improving Tyrosol Production

open access: yesFrontiers in Bioengineering and Biotechnology, 2019
Tyrosol is extensively used in the pharmaceutical industry as an important natural product from plants. In this study, an exogenous pathway involved in catalyzing tyrosine to tyrosol was introduced into Saccharomyces cerevisiae. Furthermore, The pyruvate

A Nutrient‐Based Biostimulant Application Partially Alleviates Negative Effects of Glyphosate Drift on Wheat

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT The extensive use of glyphosate for weed control in‐crop poses significant risks to non‐target crops, such as wheat, due to spray drift. Biostimulants are widely used to improve nutrient uptake, stimulate root growth, and enhance tolerance to abiotic stress. These growth effects of biostimulants may aid in alleviating glyphosate‐induced damage

Unlock the Potential of Pichia in Coffee: Knowledge Transfer From Fermented Beverages

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Considerable research has focused on non‐Saccharomyces yeasts to explore their biochemical potential and genetic diversity beyond the capabilities of the conventional starter culture, Saccharomyces cerevisiae. Among these, species of the genus Pichia have emerged as promising candidates in diverse food fermentation systems. Although studies on

Pesticide Residues, Gut Microbiota, and Gastrointestinal Outcomes: A Scoping Review of Human Evidence

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Vegetables anchor healthy‐diet recommendations yet are the principal nonoccupational route by which residues of organophosphate (OP), pyrethroid, neonicotinoid, organochlorine (OC), and glyphosate herbicide enter the diet, with the gut microbiota a plausible mediator linking these residues to functional gastrointestinal (GI) and inflammatory ...

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

open access: yesPlant Biotechnology Journal, Volume 24, Issue 9, Page 5114-5130, September 2026.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

The shikimic acid pathway and polyketide biosynthesis

open access: yesJournal of Industrial Microbiology and Biotechnology, 1998
The shikimic acid pathway, ubiquitous in microorganisms and plants, provides precursors for the biosynthesis of primary metabolites such as the aromatic amino acids and folic acid. Several branchpoints from the primary metabolic pathway also provide aromatic and, in some unusual cases, nonaromatic precursors for the biosynthesis of secondary ...

4-Coumarate 3-hydroxylase in the lignin biosynthesis pathway is a cytosolic ascorbate peroxidase

open access: yesNature Communications, 2019
Lignin biosynthesis in higher plants relies upon a 3-hydroxylation reaction that can occur via shikimate esters of 4-coumarate. Here, Barros et al. define an alternative biosynthetic pathway via cytosolic ascorbate peroxidase that can catalyze direct 3 ...

Supervised Restricted Data Fusion With Common, Local, and Distinct Components

open access: yesJournal of Chemometrics, Volume 40, Issue 8, August 2026.
ABSTRACT In multi‐block data, the dominant sources of variation are not always most relevant to a response of interest, meaning that purely exploratory decompositions may fail to recover subtle but important response‐associated structure. We introduce PESCAR, a supervised extension of Penalised Exponential Simultaneous Component Analysis (PESCA) that ...
