Seasonal Changes Affect Root Prunasin Concentration in Prunus serotina and Override Species Interactions between P. serotina and Quercus petraea

Flavonoids from Prunus serotina Ehrh.

In the course of chemotaxonomic study of the genus Prunus, seven flavonol glycosides were isolated from the leaves of Prunus serotina Ehrh., characterized by UV and NMR spectroscopy, and identified finally as three quercetin monosides: hyperoside, avicularin, reynoutrin, three quercetin biosides: 3-O-(6"-O-alpha-L-rhamnopyranosyl)-beta-D-glucopyranoside, 3-O-(2"-O-alpha-L-rhamnopyranosyl)-beta-...

Virulence of soil-borne pathogens and invasion by Prunus serotina.

*Globally, exotic invaders threaten biodiversity and ecosystem function. Studies often report that invading plants are less affected by enemies in their invaded vs home ranges, but few studies have investigated the underlying mechanisms. *Here, we investigated the variation in prevalence, species composition and virulence of soil-borne Pythium pathogens associated with the tree Prunus serotina ...

Seasonal changes in carbon and nitrogen compound concentrations in a Quercus petraea chronosequence.

Forest productivity declines with tree age. This decline may be due to changes in metabolic functions, resource availability and/or changes in resource allocation (between growth, reproduction and storage) with tree age. Carbon and nitrogen remobilization/storage processes are key to tree growth and survival. However, studies of the effects of tree age on these processes are scarce and have not...
