Differential Functional Constraints Cause Strain-Level Endemism in Polynucleobacter Populations. [PDF]

open access: yes, 2016
The adaptation of bacterial lineages to local environmental conditions creates the potential for broader genotypic diversity within a species, which can enable a species to dominate across ecological gradients because of niche flexibility.

Gene clustering in plant specialized metabolism

open access: yesCurrent Opinion in Biotechnology, 2014
Physically linked clusters of genes that encode the enzymatic information for the synthesis of specialized metabolites are a well-established feature of microbial secondary metabolism. In contrast, the biosynthesis of plant specialized metabolites has until recently been thought to be almost exclusively encoded by genes that are randomly scattered in ...

An Integrated Analytical Approach Reveals Trichome Acylsugar Metabolite Diversity in the Wild Tomato Solanum pennellii

open access: yesMetabolites, 2020
Acylsugars constitute an abundant class of pest- and pathogen-protective Solanaceae family plant-specialized metabolites produced in secretory glandular trichomes.

Ecological convergence in phytochemistry and flower–insect visitor interactions along an Andean elevation gradient

open access: yesEcology and Evolution, 2023
The diversity of specialized molecules produced by plants radiating along ecological gradients is thought to arise from plants' adaptations to local conditions.

Triterpene Structural Diversification by Plant Cytochrome P450 Enzymes

open access: yesFrontiers in Plant Science, 2017
Cytochrome P450 monooxygenases (P450s) represent the largest enzyme family of the plant metabolism. Plants typically devote about 1% of the protein-coding genes for the P450s to execute primary metabolism and also to perform species-specific specialized ...

Bridging the gap between the micro- and the macro-world of tumors [PDF]

open access: yes, 2012
At present it is still quite difficult to match the vast knowledge on the behavior of individual tumor cells with macroscopic measurements on clinical tumors.

Nutritional and Behavioral Intervention for Long‐Term Childhood Acute Leukemia Survivors With Metabolic Syndrome

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Metabolic syndrome (MetS) is a common complication in survivors of childhood acute lymphoblastic and myeloid leukemia (AL), and a major risk factor for premature cardiovascular disease, type‐2‐diabetes, and metabolic dysfunction‐associated steatotic liver disease (MASLD).

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Sexual dysfunction in women with newly diagnosed thyroid dysfunction: a novel report from Basrah, Iraq

open access: yesJournal of Biological Research
Thyroid dysfunction has been proposed as a potential contributor to Female Sexual Dysfunction (FSD), yet its impact, particularly in subclinical and autoimmune forms, remains controversial, especially in culturally conservative populations.

Genome-Wide Analysis of Serine Carboxypeptidase-Like Acyltransferase Gene Family for Evolution and Characterization of Enzymes Involved in the Biosynthesis of Galloylated Catechins in the Tea Plant (Camellia sinensis)

open access: yesFrontiers in Plant Science, 2020
Tea (Camellia sinensis L.) leaves synthesize and concentrate a vast array of galloylated catechins (e.g., EGCG and ECG) and non-galloylated catechins (e.g., EGC, catechin, and epicatechin), together constituting 8%–24% of the dry leaf mass.
