Geographic variation in picea glauca in British Columbia

2011
The principal objective of the study is the determination of geographic variation in white spruce in British Columbia. Since variation within this species in British Columbia is greatly influenced by hybridization with other spruce species, an attempt is made to demarcate zones of hybridization, and evaluate its effect on variation in white spruce.

A Transient Assay for Heterologous Promoter Activity in Picea Glauca

1991
One important aspect of the successful genetic engineering of trees is the proper and coordinated expression of introduced foreign genes in the tree. To date, few studies have focused on the controlled expression of foreign genes in forest trees. Using electrical discharge particle acceleration, the expression of several heterologous promoters were ...

Differences in crown characteristics between black (Picea mariana) and white spruce (Picea glauca)

Canadian Journal of Forest Research, 2012
Black spruce ( Picea mariana (Mill.) Britton, Sterns & Poggenb.) and white spruce ( Picea glauca (Moench) Voss) are phylogenetically proximal species that differ in productivity. Crown characteristics of these two species have not been extensively studied, in spite of the importance of these two species to the Canadian boreal forest and the ...

Nitrogen-15 NMR studies of nitrogen metabolism in Picea glauca buds

Plant Physiology and Biochemistry, 2004
In vivo (15)N nuclear magnetic resonance (NMR) as well as (15)N solid-state magic angle spinning (MAS) NMR spectroscopy were used to investigate nitrogen metabolism in cultured white spruce (Picea glauca) buds. Long-term as well as short-term experiments were carried out involving the use of inhibitors of the nitrogen pathways such as methionine ...

Expression of inducible angiosperm promoters in a gymnosperm,Picea glauca (white spruce)

Plant Molecular Biology, 1991
Electrical discharge particle acceleration was used to test the transient expression of numerous inducible angiosperm promoters in a gymnosperm Picea glauca (white spruce). Promoter expression was assayed in three different tissues capable of in vitro regeneration, zygotic embryos, seedlings and embryogenic callus.

Cryopreservation of interior spruce (Picea glauca engelmanni complex) embryogenic cultures

Plant Cell Reports, 1994
Embryogenic cultures of interior spruce derived from 12 full-sib families were subjected to cryopreservation, with a 97 % success rate for 357 genotypes. Analyses suggested that cryotolerance was not related to family ranking (height increment), embryogenic potential or culture dispersability in suspension, and long-term storage in or above liquid ...

Transformation of white spruce (Picea glauca) somatic embryos by microprojectile bombardment

Plant Cell Reports, 1993
Cotyledonary somatic embryos of white spruce [Picea glauca (Moench) Voss] were subjected to microprojectile bombardment with a gene construct containing a gus::nptll fusion gene. Somatic embryos were used to re-induce the embryogenic tissue after bombardments.
