Effects of virus infection on release of volatile organic compounds from insect-damaged bean, Phaseolus vulgaris [PDF]

, 2003
Insects can serve as important vectors of plant pathogens, especially viruses. Insect feeding on plants causes the systemic release of a wide range of plant volatile compounds that can serve as an indirect plant defense by attracting natural enemies of ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Overexpression of Phenylalanine Ammonia-Lyase in Transgenic Roots of Coleus blumei Alters Growth and Rosmarinic Acid Synthesis

Food Technology and Biotechnology, 2011
Most natural phenolic compounds in plants are derived from trans-cinnamic acid, formed by the nonoxidative deamination of L-phenylalanine by phenylalanine ammonia-lyase (EC 4.3.1.24). Although a strict line between primary and secondary metabolism cannot

Regulation of L-phenylalanine ammonia-lyase from Rhizoctonia solani [PDF]

Journal of Bacteriology, 1976
Maximal levels of L-henylalanine ammonia-lyase activity were observed when the mycelial felts of Rhizoctonia solani were grown for 4.5 days on Byrde synthetic medium containing 3.5% glucose and 0.3% L-phenylalanine, Differential centrifugation studies have indicated that the enzyme is localized in the soluble fraction. The time course of induction of L-

Taxonomic and functional shifts in the microbiome of severely obese, prediabetic patients: Ketogenic diet versus energy‐matched standard diet

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Obesity and type 2 diabetes mellitus (T2DM) are among the leading global health challenges of the 21st century. While caloric restriction remains the cornerstone of weight loss interventions, ketogenic diets (KD), characterised by low carbohydrate and high fat intake, have been shown to improve metabolic health partly by modulating the ...

Molecular genetics of naringenin biosynthesis, a typical plant secondary metabolite produced by Streptomyces clavuligerus [PDF]

, 2015
Background: Some types of flavonoid intermediates seemed to be restricted to plants. Naringenin is a typical plant metabolite, that has never been reported to be produced in prokariotes.

Root Growth and Enzymes Related to the Lignification of Maize Seedlings Exposed to the Allelochemical L-DOPA

The Scientific World Journal, 2013
L-3,4-Dihydroxyphenylalanine (L-DOPA) is a known allelochemical exuded from the roots of velvet bean (Mucuna pruriens L. Fabaceae). In the current work, we analyzed the effects of L-DOPA on the growth, the activities of phenylalanine ammonia-lyase (PAL),

The targeted metabolomic profile of laticifers in rubber tree

Journal of Integrative Plant Biology, EarlyView.
Targeted metabolomic profiling of rubber tree (Hevea brasiliensis) laticifers identified metabolites that were reprogramming by domestication, revealed active isoprenoid metabolism in the laticifers, and discovered loci with potential biosynthetic applications, supporting the potential of developing laticifers as bioreactors for production of valuable ...
