Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

open access: yesAdvanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

A Tetrahydroisoquinoline-monoterpene Glucoside and an Iridoid Glucoside from Alangium kurzii.

open access: yesChemical and Pharmaceutical Bulletin, 2000
From the leaves of Alangium kurzii, a new tetrahydroisoquinoline-monoterpene glucoside, 6-O-methyl-N-deacetylipecosidic acid and a new iridoid glucoside, 10-O-benzoyladoxosidic acid, were isolated along with alangiside, demethylalangiside, 6''-O-beta-D-glucosylhenryoside, uridine and four known flavonoid glycosides.

High Tree Species Diversity Promotes Thermal Enhancement Response of Microbial Carbon Use Efficiency

open access: yesAdvanced Science, EarlyView.
ABSTRACT Predicting soil carbon dynamics under warming is constrained by limited understanding of microbial thermal adaptation, particularly whether microbial carbon use efficiency (CUE) can adapt to warming and how plant diversity modulates this response. Using soils from a natural tree species diversity gradient in a subtropical forest, we combined a

Regioselective Hydroxylation and Glucosylation of α- and β-Pinenes with Cultured Cells of

open access: yesNatural Product Communications, 2013
Cultured plant cells of Eucalyptus perriniana regioselectively hydroxylated (+)- and (-)-α-pinenes to the corresponding (+)- and (-)-verbenols. In addition, (+)-and (-)-verbenols were converted into mono-β-D-glucosides.

A β-glucosidase-producing M-2 strain: Isolation from cow dung and fermentation parameter optimization for flaxseed cake

open access: yesAnimal Nutrition, 2019
Flaxseed cake contains cyanogenic glucosides, which can be metabolized into hydrocyanic acid in an animal's body, leading to asphyxia poisoning in cells. Beta-glucosidase is highly efficient in degrading cyanogenic glucosides.

Multi‐tissue Metabolic GWAS and Drought‐Responsive Multi‐omics Reveal the Genetic Basis of the Quinoa Metabolome

open access: yesAdvanced Science, EarlyView.
A multi‐omics framework combining multitissue genome‐wide association studies, metabolomics, transcriptomics, proteomics, and functional validation uncovers the genetic basis of specialized metabolism in quinoa. The study identifies hundreds of metabolite‐associated loci, prioritizes candidate genes for saponin, betalain, and flavonoid biosynthesis ...

Studies on Monoterpene Glucosides. VII. Iridoid Glucosides of Paederia scandens

open access: yesChemical and Pharmaceutical Bulletin, 1969
Four new glucosides, paederoside (II), paederosidic acid (III), scandoside (IV) and deacetylasperuloside (V) along with asperuloside (I) were isolated as iridoid glucosides from Paederia scandens (LOUR.) MERRILL var. mairei (Leville) HARA and their structures were established. II and III are sulfur-containing glucosides.

Adaptive Responses of Tropical Crops: A Multi‐Scale Omics Integrated Perspective

open access: yesAdvanced Science, EarlyView.
Tropical crops integrate genomic, morphological, physiological, and ecological adaptations to thrive under extreme and variable environments. This review highlights how natural selection, domestication, and breeding shape stress resilience, resource‐use strategies, and productivity in sugarcane, banana, cassava, rubber and oil palm, offering new routes
