Role of the tomato MARS1/ROUGH gene encoding a LYSINE‐SPECIFIC HISTONE DEMETHYLASE 1 in adventitious root and fruit skin formation

Journal of Integrative Plant Biology, EarlyView.
The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...

GcrR in Streptococcus mutans Inhibits the Morphological Transition of Candida albicans Through Ras1–cAMP/PKA Pathway in the Cross‐Kingdom Biofilms

Molecular Oral Microbiology, EarlyView.
ABSTRACT The dual‐species biofilms formed by Streptococcus mutans and Candida albicans exhibit enhanced cariogenic potential due to the production of extracellular polysaccharides (EPSs). The response regulator GcrR in S. mutans negatively regulates EPS synthesis, but its impact on dual‐species biofilms remains unclear.

Inhibition of Clostridium difficile TcdA and TcdB toxins with transition state analogues

Nature Communications, 2021
The Clostridium difficile virulence factors TcdA and TcdB contain a glucosyltransferase domain (GTD), which has both glucohydrolase (GH) and glucosyltransferase (GT) activities. Here, the authors characterize the transition state features of the TcdA and

Purification and properties of glucosyltransferase fromAureobasidium

Journal of Industrial Microbiology, 1994
Purification and properties of glucosyltransferase, which produces panose (Glc alpha 1-->6Glc alpha 1-->4Glc) and isomaltose (Glc alpha 1-->6Glc) from maltose (Glc alpha 1-->4Glc), are reported. The enzyme, from Aureobasidium, was purified to homogeneity by fractionations involving ammonium sulfate and DEAE-Cellulofine, S-Sepharose Fast Flow and ...

Sweet Potato Gene Clusters Control Anthocyanin Biosynthesis and Leaf Morphology

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sweet potato (Ipomoea batatas) exhibits diversity in pigmentation and leaf morphology, yet the genetic architecture and regulatory organisation underlying these traits remain poorly resolved, particularly with respect to organ‐specific control.

Glucosyltransferase CsUGT78A14 Regulates Flavonols Accumulation and Reactive Oxygen Species Scavenging in Response to Cold Stress in Camellia sinensis

Frontiers in Plant Science, 2019
Glycosyltransferases (UGTs) play diverse roles in cellular metabolism by altering regulatory metabolites activities. However, the physiological roles of most members of UGTs in crops in response to abiotic stresses are unknown. We have identified a novel

DcH3.3 and DcNAC1 Regulate the Expression of UGT73A93 Involved in the Changes in Flower Colour and Fungal Resistance in Carnation

Plant Biotechnology Journal, EarlyView.
ABSTRACT Carnation (Dianthus caryophyllus) contains abundant flavonoid glycosides (FGs), which are important natural functional and colour components. However, there are few reports on the modification of UDP‐glycosyltransferases (UGTs) in relation to flavonoids in carnation.

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.

Inhibition of Glucosyltransferase Activity and Glucan Production as an Antibiofilm Mechanism of Lemongrass Essential Oil against Escherichia coli O157:H7

Antibiotics, 2020
The resistance of Escherichia coli O157:H7 to disinfection is associated with its ability to form biofilms, mainly constituted by glucans produced by glucosyltransferases.

Understanding exosomes in regenerative dentistry

Periodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.
