The evolution of a partnership-based breeding program for organic corn

open access: yesJournal of Agriculture, Food Systems, and Community Development, 2023
This paper describes decades of research develop­ing a new type of corn (maize) cultivar that utilizes partnerships with seed-borne, bacterial endophytes to create environmentally friendly, nutritious corn that is better adapted to organic farming. Over

Methionine Metabolism Alters Oxidative Stress Resistance via the Pentose Phosphate Pathway

open access: yesAntioxidants and Redox Signaling, 2016
Nutrient uptake and metabolism have a significant impact on the way cells respond to stress. The amino acid methionine is, in particular, a key player in the oxidative stress response, and acting as a reactive oxygen species scavenger, methionine is ...

Effects of Methionine Supplementation Levels in Normal or Reduced Protein Diets on the Body Composition and Femur Bone Characteristics of Broilers Challenged with Coccidia

open access: yesAnimals
This study investigated the effects of dietary methionine (Met) levels on the bone quality of broilers challenged with coccidia. A total of 600 fourteen-day-old male Cobb500 broilers were gavaged with mixed Eimeria spp.

Fructo-oligosaccharides and intestinal barrier function in a methionine–choline-deficient mouse model of nonalcoholic steatohepatitis

open access: yesPLoS ONE, 2017
Impairments in intestinal barrier function, epithelial mucins, and tight junction proteins have been reported to be associated with nonalcoholic steatohepatitis. Prebiotic fructo-oligosaccharides restore balance in the gastrointestinal microbiome.

Methionine deprivation suppresses triple-negative breast cancer metastasis in vitro and in vivo

open access: yesOncoTarget, 2016
Nutrient deprivation strategies have been proposed as an adjuvant therapy for cancer cells due to their increased metabolic demand. We examined the specific inhibitory effects of amino acid deprivation on the metastatic phenotypes of the human triple ...

Methionine residues around phosphorylation sites are preferentially oxidized in vivo under stress conditions

open access: yesScientific Reports, 2017
Protein phosphorylation is one of the most prevalent and well-understood protein modifications. Oxidation of protein-bound methionine, which has been traditionally perceived as an inevitable damage derived from oxidative stress, is now emerging as ...

Physiological and biochemical aspects of methionine isomers and a methionine analogue in broilers

open access: yesPoultry Science, 2017
&NA; Methionine is the first limiting amino acid in all poultry corn‐soybean based diets. The objective of this study was to determine the effect of supplementation of L‐methionine (L‐Met), DL‐methionine (DL‐Met), and the methionine analogue, DL‐2 ...

Effects of lipopolysaccharide infusion on feed intake, apparent digestibility, rumen fermentation and microorganisms of young Holstein bulls fed diets with different ratios of lysine and methionine

open access: yesFrontiers in Veterinary Science
The aim of this experiment was to investigate the effects of intravenous infusion of lipopolysaccharide (LPS) and feeding different ratios of lysine (Lys) and methionine (Met) on feed intake, apparent digestibility, rumen fermentation and microorganisms ...

The effect of dietary methionine on growth, antioxidant capacity, innate immune response and disease resistance of juvenile yellow catfish (Pelteobagrus fulvidraco)

open access: yes, 2016
An 11-week feeding trial was conducted to evaluate the effect of dietary methionine on the growth, antioxidant status, innate immune response and disease resistance to Aeromonas hydrophila of juvenile yellow catfish.
