Towards a structural understanding of Clostridium difficile toxins A and B

Frontiers in Cellular and Infection Microbiology, 2012
Clostridium difficile is a toxin-producing bacterium that is a frequent cause of hospital-acquired and antibiotic-associated diarrhea. The incidence, severity, and costs associated with C.

RNA‐Seq analysis revealed differentially expressed genes linked to seed size variation in sainfoin

Grassland Science, EarlyView.
Abstract Sainfoin is a perennial forage legume with many desirable characteristics such as easy to establish, bloat‐free trait for grazing ruminants and providing pollinator habitat and biological nitrogen fixation to soil. However, adoption of this species is often hindered by high seed cost associated with its larger seed size compared to other ...

Produção de isomaltulose, um substituto da sacarose, utilizando glicosiltransferase microbiana Isomaltulose production, a new sucrose substitute, using microbial glucosyl transferase

Química Nova, 2008
Isomaltulose, a functional isomer of sucrose, is a non-cariogenic reducing disaccharide; has a low glycemic index; selectively promotes growth of beneficial bifidobacteria in the human intestinal microflora; and has greater stability than sucrose in some

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

The multidimensional regulation roles and mechanisms of calcium in fruit quality

Journal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

Starch Synthase 3 isoforms are essential for normal starch granule initiation in wheat endosperm

New Phytologist, EarlyView.
Summary Wheat grains have two distinct types of starch granules. Large, lenticular A‐type granules are formed from a single initiation per amyloplast during early grain development, while numerous small B‐type granules are initiated during later grain development.

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

AGP and EXO‐LIKE genes promote brassinosteroid‐dependent anisotropic growth

New Phytologist, EarlyView.
Summary The brassinosteroid pathway promotes anisotropic cell expansion; however, the effectors in this process remain unclear. Candidates include ARABINOGALACTAN PROTEIN (AGP) genes, which are prominent brassinosteroid‐responsive transcriptional targets, and EXORDIUM (EXO)‐LIKE (EXL) genes.

Engineering of the Flavone Rutinoside Biosynthetic Pathway Enables Production of Diosmin, a Venoactive Compound in Solanum lycopersicum and Nicotiana tabacum

Plant Biotechnology Journal, EarlyView.
ABSTRACT Diosmin is often used as a dietary supplement, and it is sometimes used to make phlebotropic drugs for venous diseases. Traditionally, diosmin is obtained by the dehydrogenation of the flavanone glycoside hesperidin through chemical semisynthesis.

Two Indel Variations in the Regulated Carotenoid Pigment Gene Hold the Key to the Interspecies Flower Colour Differentiation in Liriodendron Plants

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flower colour variation is pivotal for plant evolution, ecological adaptation, and pollinator attraction. In the Liriodendron genus, L. tulipifera features a distinct orange petal stripe which is absent in L. chinense, driven by differential carotenoid accumulation, yet the underlying genetic mechanism remains unclear.
