An Effector TaCRVP From Tuta Absoluta Oral Secretion Impairs H2O2‐Mediated Plant Defense by Targeting Tomato SlCAT2

Advanced Science, EarlyView.
The Tuta absoluta salivary effector TaCRVP subverts tomato immunity by hijacking host catalase SlCAT2. Through a sophisticated dual mechanism, TaCRVP simultaneously promotes SlCAT2 tetramerization for activation and blocks its SlAdBiL‐mediated degradation for stabilization.

Integration of the D‐Genome Reshapes Gene Transcription, Chromatin Architecture, and Metabolome of Allohexaploid Wheat, Leading to Enhanced Environmental Adaptability

Advanced Science, EarlyView.
Integration of the D‐genome reshapes gene transcription, chromatin architecture, and the metabolome of hexaploid wheat, leading to enhanced adaptability to salt, UV‐B, and alkali stress. ABSTRACT The hybridization‐led integration of the D‐genome into domesticated tetraploid wheat gave rise to allohexaploid wheat, the most cultivated wheat globally ...

New Steroidal Glycoside and Flavonoid Constituents from

Natural Product Communications, 2017
Chromatographic separations of a methanolic extract of Ophiopogon japonicus tubers resulted in the isolation of a new steroidal glycoside, (25 R )-ruscogenin 1- O -(4- O -sulfo)-β-D-fucopyranoside ( 1 ), a new C -methylflavonol, 3,4′-dimethoxy-3′,5,5′,7 ...

Study of the mechanism of change in flavonoid composition in the processing of Chrysanthemum morifolium (Ramat.) Tzvel. ‘Boju’

BMC Chemistry, 2019
A form of β-glucosidase was isolated and purified from fresh Chrysanthemum morifolium (Ramat.) Tzvel. ‘Boju’ (Boju) and its enzymatic properties explored in this study. The purified enzyme and Boju flavonoids were reacted in a water bath to ascertain the

Enzymatic β-elimination in natural product O- and C-glycoside deglycosylation

Nature Communications, 2023
Biological degradation of natural product glycosides involves, alongside hydrolysis, β-elimination for glycosidic bond cleavage. Here, we discover an O-glycoside β-eliminase (OGE) from Agrobacterium tumefaciens that converts the C3-oxidized O-β-d ...

Oral Astilbin Nanogels Modulate Senescence‐Associated CD4+ T Cells and Promote Treg Induction in Aged Mice with Colitis

Advanced Science, EarlyView.
Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...
