Antimicrobial dihydrobenzofurans and xanthenes from a foliar endophyte of Pinus strobus.

Water relations of pine seedlings in contrasting overstory environments

Overstory conditions influence understory microclimate and resource availability, leading to gradients in evaporative demand andmoisture availability that influence seedlingwater relations. Partial canopies may either reduce seedling moisture stress by ameliorating environmental conditions, or increase moisture stress by reducing soil moisture availability. This study used stable isotope ratios...

A comparison of the community diversity of foliar fungal endophytes between seedling and adult loblolly pines (Pinus taeda).

Fungal endophytes represent one of the most ubiquitous plant symbionts on Earth and are phylogenetically diverse. The structure and diversity of endophyte communities have been shown to depend on host taxa and climate, but there have been relatively few studies exploring endophyte communities throughout host maturity. We compared foliar fungal endophyte communities between seedlings and adult t...

Late Eocene white pines (Pinus subgenus Strobus) from southern China

Fossil records indicate that the genus Pinus L. split into two subgenera by the Late Cretaceous, although subgenus Strobus (D. Don) Lemmon is less well documented than subgenus Pinus L., especially in eastern Asia. In this paper, Pinus maomingensis sp. nov. is established based on a compressed seed cone from the upper Eocene of the Maoming Basin of southern China. This species is attributed to ...

Genetic relationships of endophytic Lophodermium nitens isolates from needles of Pinus strobus

The foliage of Pinus strobus (eastern white pine), as that of all other conifers examined, is occupied by endophytic fungi, the most frequent of which is Lophodermium nitens. The number and extent of endophytic infections and the genetic relationship of individual isolates within living needles as well as their relationship to isolates from forest floor needles is unknown. To examine these and ...
