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 ...

Squalene Cyclases and Cycloartenol Synthases from Polystichum polyblepharum and Six Allied Ferns

open access: yesMolecules, 2018
Ferns are the most primitive of all vascular plants. One of the characteristics distinguishing them from flowering plants is its triterpene metabolism. Most cyclic triterpenes in ferns are hydrocarbons derived from the direct cyclization of squalene by ...

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.

Synthesis and Evaluation of Anticancer Activities of Novel C-28 Guanidine-Functionalized Triterpene Acid Derivatives

open access: yesMolecules, 2018
Triterpene acids, namely, 20,29-dihydrobetulinic acid (BA), ursolic acid (UA) and oleanolic acid (OA) were converted into C-28-amino-functionalized triterpenoids 4–7, 8a, 15, 18 and 20.

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,

Protostane and Fusidane Triterpenes: A Mini-Review

open access: yesMolecules, 2013
Protostane triterpenes belong to a group of tetracyclic triterpene that exhibit unique structural characteristics. Their natural distribution is primarily limited to the genus Alisma of the Alismataceae family, but they have also been occasionally found ...

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 ...
