Expression and Function of Populus Homologs to TERMINAL FLOWER 1 Genes: Roles in Onset of Flowering and Shoot Phenology

Creator:: Mohamed, Rozi
Abstract:: We isolated and characterized the expression of two genes from Populus trichocarpa that are homologous to the TERMINAL FLOWER 1 (TFL1) gene from the model annual plant Arabidopsis. In Arabidopsis, overexpression of the TFL1 gene extends the vegetative growth phase, and the homozygous mutant tfl1 allele causes early flowering and...

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...

Stability of reporter gene expression and RNAi in transgenic poplars over multiple years in the field under vegetative propagation

Creator:: Li, Jingyi
Abstract:: Stable expression of transgenes is required for commercial uses of genetically engineered trees. To better understand the stability of transgene expression under field conditions, we studied transgene expression and RNA interference (RNAi)-induced transgene suppression in 2,480 transgenic poplars (460 transgene insertion events) over three years. Stability of expression was assessed...

Identification and Functional Characterization of Genes that Regulate Biomass Production, Floral Development, and Leaf Senescence in Populus Species using Genetic Engineering and Bioinformatics Tools

Creator:: Lu, Haiwei
Abstract:: This dissertation is comprised of four studies on different elements of Populus biotechnology and genomic science: 1) growth improvement by recombinant DNA (rDNA) modification of gibberellin (GA) metabolism; 2) gene editing using zinc-finger nucleases (ZFNs); 3) induction of floral sterility by RNA interference (RNAi) of AGAMOUS (AG) gene homologs; and...

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,...

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...

Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

Creator:: Wang, Yueju
Abstract:: The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

Application of Infrared Spectroscopy for Determination of Wood Natural Durability

Creator:: Lipeh, Shahlinney
Abstract:: Natural durability remains one of the most attractive characteristics of wood, and helps wood obtain a premium price. A worldwide shift towards the use of younger trees from intensively managed forests has created greater concerns about wood quality, especially the wood’s resistance to fungi and insects. Wood durability is assessed...

Variable sampling compensation of networked control systems with delays using neural networks

Creator:: Lopez-Echevarria, Daniel
Abstract:: In networked control systems (NCS) information or packets usually flow from a sensor or a set of sensors to a remotely located controller. Then the controller processes the received information and sends a series of control commands to the actuators through a communication network which could be either wireless or...
