Chloroplast DNA variability and phylogeny in the California closed cone pines

Creator:: Hong, Yong-pyo, 1958-
Abstract:: Chloroplast DNA (cpDNA) variability and phylogeny were studied via analysis of restriction site mutations and DNA sequencing in a complex of three closely related species of pines: Pinus radiata D. Don, P. attenuata Lemm., and muricata D. Don. Genomic DNA from 384 trees representing 20 populations in the complex were...

Overexpression of the GROWTH REGULATING FACTOR 4-GRF-INTERACTING FACTOR 1 Transcription Factor Chimera Modifies Transformation and Regeneration Efficiency in Populus and Eucalyptus

Creator:: Ryan, Nathaniel W.
Abstract:: Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...

Evaluation of transgenes for stress tolerance, lignin modification, and growth enhancement in poplar

Creator:: Elias, Ani Anna
Abstract:: We evaluated genes previously identified from a large scale functional genomics screen for their potential value to help enhance carbon sequestration in planted trees. We used poplar as a model tree species because of its abundant genetic variation, ease of gene transfer, and availability of large databases for genomic, anatomical,...

Nuclear and mitochondrial DNA polymorphism and phylogeny in the California closed-cone pines

Creator:: Wu, Junyuan
Abstract:: We studied genetic polymorphism and phylogeny using nuclear random amplified polymorphic DNA markers (RAPDs) and mitochondrial DNA (mtDNA) restriction fragment length polymorphisms (RFLPs) in the three California Closed-Cone Pines: Pinus attenuata Lemm., P. muricata D. Don, and P. radiata D. Don. A total of 343 to 384 trees derived from...

Dispersed repetitive sequences in the chloroplast genome of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Tsai, Ching-Hsiu
Abstract:: Chloroplast genomes of conifers are unusual in a number of respects, including the possession of much repetitive DNA. By studying the distribution and sequences of dispersed repetitive DNA, I hoped to gain insight into the mechanisms of chloroplast genome evolution. I used restriction mapping and DNA sequencing to characterize dispersed...

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...

Maintenance of normal vegetative growth via attenuation of barnase as an agent of floral tissue ablation in Populus

Creator:: Wei, Hao
Abstract:: To reduce the environmental impacts caused by gene flow from transgenic trees, reproductive sterility genes have been developed that use a floral regulatory element linked to a cell toxin. This results in dysfunction or ablation of floral tissues, causing sterility. However, floral promoters often permit low levels of expression in...

Functional Characterization and Classification of Genes Essential to Flower Induction, Flower Development, and Seed Development in Populus and Eucalyptus

Creator:: Elorriaga, Estefania
Abstract:: This dissertation consists of four studies of Populus and Eucalyptus biotechnology and genomic science: 1) induction of floral sterility by tapetal expression of the ribonuclease Barnase in Populus; 2) CRISPR Cas9-mediated gene editing targeting LEAFY (LFY) and AGAMOUS (AG) homologs in Populus; 3) induction of floral sterility by CRISPR Cas9...

Sequence Analysis and Vegetative Growth in Transgenic Eucalyptus with CRISPR-Cas9-induced Mutations in the Eucalyptus Homologs of the Floral Genes EMBRYO DEVELOPMENT ARREST 33 (EDA33) and TAPETAL DEVELOPMENT AND FUNCTION1 (TDF1)

Creator:: Nahata, Surbhi S.
Abstract:: An impediment to use of exotic and bioengineered trees in many places is their propensity for spread by pollen and/or seeds. Our laboratory has been using gene editing to induce mutations in floral genes as means to impart stable and reliable genetic containment when this is desirable from social (markets,...
