Polymorphism of the Polyketide Synthase Gene phlD in Biocontrol Fluorescent Pseudomonads Producing 2,4-Diacetylphloroglucinol and Comparison of PhlD with Plant Polyketide Synthases

open access: yesMolecular Plant-Microbe Interactions, 2001
Many biocontrol fluorescent pseudomonads can protect plants from soilborne fungal pathogens through production of the antifungal secondary metabolite 2,4-diacetylphloroglucinol (Phl). One of the phl biosynthetic genes, phlD, encodes a polyketide synthase

The Regulation of Floral Colour Change in Pleroma raddianum (DC.) Gardner

open access: yesMolecules, 2020
Floral colour change is a widespread phenomenon in angiosperms, but poorly understood from the genetic and chemical point of view. This article investigates this phenomenon in Pleroma raddianum, a Brazilian endemic species whose flowers change from white

Differential Expression of Eight Chitinase Genes in Medicago truncatula Roots During Mycorrhiza Formation, Nodulation, and Pathogen Infection

open access: yesMolecular Plant-Microbe Interactions, 2000
Expression of eight different chitinase genes, representing members of five chitinase classes, was studied in Medicago truncatula roots during formation of arbuscular mycorrhiza with Glomus intraradices, nodulation with Rhizobium meliloti, and pathogen ...

AfCHIL, a Type IV Chalcone Isomerase, Enhances the Biosynthesis of Naringenin in Metabolic Engineering

open access: yesFrontiers in Plant Science, 2022
Naringenin is an essential precursor for all flavonoids, and effectively promoting naringenin production is crucial in metabolic engineering. The interaction between plant metabolic enzymes ensures metabolic flux.

Structure and mechanism of chalcone synthase-like polyketide synthases

open access: yesJournal of Industrial Microbiology and Biotechnology, 2001
Polyketide synthases (PKS) produce an array of natural products with different biological activities and pharmacological properties by varying the starter and extender molecules that form the final polyketide. Recent studies of the simplest PKS, the chalcone synthase (CHS)-like enzymes involved in the biosynthesis of flavonoids, anthocyanin pigments ...

Differential Expression of Benzophenone Synthase and Chalcone Synthase in Hypericum Sampsonii [PDF]

open access: yesNatural Product Communications, 2012
cDNAs encoding Hypericum sampsonii benzophenone synthase (HsBPS) and chalcone synthase (HsCHS) were isolated and functionally characterized. Differential expressions of HsBPS and HsCHS were monitored using quantitative polymerase chain reaction (PCR).

Virus-induced silencing of MYB and WD40 transcription factor genes affects the accumulation of anthocyanins in chilli pepper fruit

open access: yesBiologia Plantarum, 2014
The MYB, MYC, and WD40 transcription factors (TFs) are known to regulate the expression of structural biosynthetic genes at different steps depending on the plant species. In this work, we used an agroinfiltration protocol with Tobacco rattle virus (TRV)
