Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families
Plant, Cell &Environment, EarlyView.ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Phosphorylation of ornithine decarboxylase in intact erythroleukemia cells
, 1990 32P-labeled ornithine decarboxylase was isolated by immunoprecipitation from murine erythroleukemia cells incubated in a medium containing [32P]ortophosphoric acid.

Plant, Cell &Environment, EarlyView.ABSTRACT Plants maintain energy balance under salinity stress through increased respiration and energy use, processes also associated with reactive oxygen species generation. Although respiration imposes a high energy cost, mitochondrial respiration and the tricarboxylic acid (TCA) cycle activity are vital for ATP production and for providing electron ...

In vivo hormonal induction of ornithine decarboxylase in rat kidney
, 1976 Single pharmacological doses of parathyroid hormone, calcitonin, vasopressin, d-aldosterone, or L-triiodothyronine produced a significant increase in the ornithine decarboxylase activity of rat kidney.

Plant, Cell &Environment, EarlyView.ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

Biologia Plantarum, 2020 Nitric oxide plays an important role in regulating adaption of the model alga Chlamydomonas reinhardtii to various environmental stresses. One response to abiotic stresses is the accumulation of protective molecules such as proline and putrescine. The NO

PURIFICATION AND CHARACTERIZATION OF BOVINE LIVER ORNITHINE DECARBOXYLASE
, 1980 Ornithine decarboxylase has been purified to apparent homogeneity from thioacetamide-stimulated calf liver. The purification process, which has been developed to circumvent the lability of the enzyme, employs ion exchange chromatography, gel filtration ...

A quantitative cytochemical method for ornithine decarboxylase activity.
, 1990 Although decarboxylases, particularly ornithine decarboxylase, are of considerable importance in cell metabolism, it has been impossible to demonstrate their activity histochemically, as this depends on trapping carbon dioxide at neutral pH values.

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola
Insect Molecular Biology, Volume 35, Issue 5, Page 576-593, October 2026.Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Cell Biochemistry and Function, Volume 44, Issue 9, September 2026.ABSTRACT Cancer cells undergo metabolic reprogramming to sustain proliferation, resist apoptosis, and adapt to oxidative stress. In the present study, we comparatively evaluated the anticancer effects of four medicinal plant extracts (Inula helenium, Hypericum alpestre, Rumex obtusifolius, and Alchemilla smirnovii) on HeLa cervical cancer cells, with ...
