A novel class of plant type III polyketide synthase involved in orsellinic acid biosynthesis from Rhododendron dauricum

Frontiers in Plant Science, 2016
Rhododendron dauricum L. produces daurichromenic acid, the anti-HIV meroterpenoid consisting of sesquiterpene and orsellinic acid moieties. To characterize the enzyme responsible for orsellinic acid biosynthesis, a cDNA encoding a novel polyketide ...

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

Plant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Reprogramming of the Aurantinin Polyketide Assembly Line to Synthesize Auritriacids by Excising an Atypical Enoyl‐CoA Hydratase Domain

Advanced Science
Modular polyketide synthases (PKSs) are capable of synthesizing diverse natural products with fascinating bioactivities. Canonical enoyl‐CoA hydratases (ECHs) are components of the β‐branching cassette that modifies the polyketide chain by adding a β ...

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 ...

The architecture of polyketide synthases

, 2023
Since the discovery of penicillin over a century ago, secondary metabolites from all kingdoms of life have proven to be of high medical value. One class of proteins prevalent in the production of secondary metabolites are polyketide synthases (PKSs).

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

Evidence for an iterative module in chain elongation on the azalomycin polyketide synthase

Beilstein Journal of Organic Chemistry, 2016
The assembly-line synthases that produce bacterial polyketide natural products follow a modular paradigm in which each round of chain extension is catalysed by a different set or module of enzymes.

Draft genome sequence of a human-associated isolate of Haloferax alexandrinus strain Arc-hr, an extremely halophilic archaea

New Microbes and New Infections, 2017
We report the draft genome sequence of Haloferax alexandrinus strain Arc-hr (CSUR P798), isolated from the human gut of a 10-year-old Amazonian individual. Its 3 893 626 bp genome exhibits a 66.00% GC content.

Advances in large DNA fragment assembly for microbial cell factory engineering

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

Exploiting the Biosynthetic Potential of Type III Polyketide Synthases

Molecules, 2016
Polyketides are structurally and functionally diverse secondary metabolites that are biosynthesized by polyketide synthases (PKSs) using acyl-CoA precursors.
