Triterpene saponins fromMyrsine pellucida

open access: yesPhytochemistry, 1994
Quercitol, five saponins and 3-O-(6'-O-palmitoyl) beta-D-glucopyranosyl stigmasterol were isolated from the stem bark of Myrisine pellucida. These compounds are described for the first time in this plant and their structures were determined using a combination of 1H and 13C NMR, and mass spectroscopy.

The Effect of Myrtacine and Celastrol‐Enriched Extract on Cutibacterium acnes Extracellular Vesicles

open access: yesInternational Journal of Dermatology, EarlyView.
Myrtacine alone, Celastrol‐enriched extract alone, or the combination of both ingredients were added to the culture medium either before (preventive condition) or after (modulating condition) incubation with C. acnes IA1 extracellular vesicles (EVs) from healthy and acne skin in immortalized keratinocytes (HaCaT cells) and human skin explants.

Triterpene glycosides from Agrostemma gracilis

open access: yesPhytochemistry, 2010
Four triterpene saponins, agrostemmosides A-D were isolated from the methanol extract of Agrostemma gracilis. The structures of the compounds were determined as 3-O-beta-D-xylopyranosyloleanolic acid 28-O-beta-D-glucopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->6)]-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester, 3-O-alpha-L-rhamnopyranosyl ...

Chromosome‐Scale Haplotype Genome Assemblies for the Australian Mango ‘Kensington Pride’ and a Wild Relative, Mangifera laurina, Provide Insights Into Anthracnose‐Resistance and Volatile Compound Biosynthesis Genes

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Mango (Mangifera indica) is one of the most popular fruits cultivated in tropical and subtropical regions of the world. The availability of reference genomes helps to identify the genetic basis of important traits. Here, we report assembled high‐quality chromosome‐level genomes for the Australian mango cultivar ‘Kensington Pride’ and M ...

Distinct Defence Mechanisms of Allelopathic Rice Against Quinclorac‐Susceptible and ‐Resistant Barnyardgrass: Involvement of Specific Metabolites and Rhizosheath Microbiota

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,

Analysis of BpbHLH Gene Family Responsive to MeJA Signalling in Betula platyphylla Suk. and Functional Mechanisms of BpbHLH42/44 in Genetic Improvement and Triterpenoid Biosynthesis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The basic helix–loop–helix (bHLH) transcription factor family regulates plant secondary metabolism, development and stress responses. Although triterpenoids such as betulinic acid (BA), betulin (BT) and oleanolic acid (OA) from Betula platyphylla Suk.
