The accumulation of active ingredients of Polygonatum cyrtonema Hua is associated with soil characteristics and bacterial community

Frontiers in Microbiology
IntroductionWith the increasing demand for health products derived from Polygonati rhizoma (PR), people begin to artificially plant Polygonatum cyrtonema Hua (P. cyrtonema) in the middle and lower reaches of the Yangtze River. To promote P.

Screening of cadmium resistant bacteria and their growth promotion of Sorghum bicolor (L.) Moench under cadmium stress

Ecotoxicology and Environmental Safety
Heavy metal pollution of agricultural soils, especially from cadmium (Cd) contaminationcaused serious problems in both food security and economy. Sorghum bicolor (L.) showed a great potential in phytoremediation of Cd contamination due to its fast growth,

Secondary metabolism and pathophysiology [PDF]

Folia Microbiologica, 1985
Mechanisms of regulation of biosynthesis of secondary metabolites in microorganisms under natural conditions differ from the regulation mechanisms resulting in an overproduction of these metabolites in industrial fermentations. The overproduction is attained by creating pathophysiological cultivation conditions and by using mutant strains which differ ...

Regulation of fungal secondary metabolism [PDF]

Nature Reviews Microbiology, 2012
Fungi produce a multitude of low-molecular-mass compounds known as secondary metabolites, which have roles in a range of cellular processes such as transcription, development and intercellular communication. In addition, many of these compounds now have important applications, for instance, as antibiotics or immunosuppressants.

Engineering of Secondary Metabolism

Annual Review of Genetics, 2015
Secondary (specialized) metabolites, produced by bacteria, fungi, plants, and other organisms, exhibit enormous structural variation, and consequently display a wide range of biological activities. Secondary metabolism improves and modulates the phenotype of the host producer.

Secondary metabolism in cannabis

Phytochemistry Reviews, 2008
Cannabis sativa L. is an annual dioecious plant from Central Asia. Cannabinoids, flavonoids, stilbenoids, terpenoids, alkaloids and lignans are some of the secondary metabolites present in C. sativa. Earlier reviews were focused on isolation and identification of more than 480 chemical compounds; this review deals with the biosynthesis of the secondary

Plant Secondary Metabolism

1999
Biotechnological exploitation of plant cell cultures for production of natural products will depend on our ability to modify expression of complex biosynthetic pathways both quantitatively and qualitatively. De novo, transcriptional activation of genes encoding biosynthetic pathway enzymes represents the first, and often the major, control point for ...

Secondary metabolism in the lichen symbiosis

Chemical Society Reviews, 2018
Lichens, which are defined by a symbiosis between a mycobiont (fungal partner) and a photobiont (photoautotrophic partner), are in fact complex assemblages of microorganisms that constitute a largely untapped source of bioactive secondary metabolites.

Origins of secondary metabolism.

Ciba Foundation symposium, 1993
Secondary metabolites generally benefit their producers as poisons that protect them against competitors, predators or parasites. They are produced from universally present precursors (most often acetyl-CoA, amino acids or shikimate) by specific enzymes that probably arose by the duplication and divergence of genes originally coding for primary ...
