Genetic engineering of disease resistance in poplar : effects of bacterio-opsin over-expression and analysis of a copper-based system for resistance-gene activation

Creator:

Mohamed, Rozi

Abstract:

We tested a synthetic bacterio-opsin (bO) gene derived from Halobacterium halobium for its effect on disease resistance in transgenic poplar hybrids, and assessed a genetic system for controlling expression of this gene. In tobacco the bO gene caused necrotic lesions similar to an induced hypersensitive response (HR), increased levels of...

Effects of environment and genetics on western pine shoot borer, Eucosma sonomana, infestation levels in ponderosa pine plantations of central Oregon

Creator:

Prueitt, Sara C.

Abstract:

Infestations of the western pine shoot borer (Eucosma sonomana Kearfott) in young stands of ponderosa pine (Pinusponderosa Lawson), were surveyed on the Deschutes National Forest. Elevation, slope, aspect, tree height, tree diameter, number of shoots in the terminal whorl, stand density, stand age and plant association for each stand were...
