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 ...

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).

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

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.

Transcriptome-sequencing analyses reveal flower color formation in Strelitzia reginae

open access: yesBiologia Plantarum, 2020
Strelitzia reginae is a popular cut flower that has blue petals and orange sepals. Flower color is an important plant trait; however, little is known about its molecular mechanisms in S. reginae.

Cross‐reaction of chalcone synthase and stilbene synthase overexpressed in Escherichia coli [PDF]

open access: yesFEBS Letters, 1999
Chalcone synthase (CHS) and stilbene synthase (STS) are related plant polyketide synthases belonging to the CHS superfamily. CHS and STS catalyze common condensation reactions of p‐coumaroyl‐CoA and three C2‐units from malonyl‐CoA but different cyclization reactions to produce naringenin chalcone and resveratrol, respectively.

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)
