Sucrose Phosphate Synthase Expression Influences Poplar Phenology, Thomas Canam, Ji-Young Park, Kyu-Young Kang, Faride Unda, Shawn D. Mansfield Jan 2009

Sucrose Phosphate Synthase Expression Influences Poplar Phenology, Thomas Canam, Ji-Young Park, Kyu-Young Kang, Faride Unda, Shawn D. Mansfield

Thomas Canam

The objective of this study was to manipulate the intracellular pools of sucrose, and investigate its role in regulating plant growth, phenology (leaf senescence and bud break) and fibre development. This objective was achieved by differentially expressing an Arabidopsis (Arabidopsis thaliana L. Heynh.) sucrose phosphate synthase (SPS) gene in hybrid poplar (Populus alba · Populus grandidentata Michx.), a model system for tree biology with substantial industrial relevance in the context of short rotation forestry and a target bioenergy crop. Phenotypic differences were evident in the transgenic trees, as both the timing of bud flush and leaf senescence were altered compared …

Spatial And Temporal Expression Profiling Of Cell-Wall Invertase Genes During Early Development In Hybrid Poplar, Thomas Canam, Sarah W.Y. Mak, Shawn D. Mansfield Jan 2008

Spatial And Temporal Expression Profiling Of Cell-Wall Invertase Genes During Early Development In Hybrid Poplar, Thomas Canam, Sarah W.Y. Mak, Shawn D. Mansfield

Thomas Canam

Cell-wall invertase genes are spatially and temporally regulated in several plant species, including Daucus carota L., Lycopersicon esculentum L. and Solanum tuberosum L. However, few studies of cell-wall invertase genes of trees have been conducted, despite the importance of trees as a source of lignocellulosic biopolymers.We identified three putative cell-wall invertase genes in hybrid poplar (Populus alba L. × grandidentata Michx.) that showed higher homology to each other than to cell-wall invertases of other dicotyledonous species, with two of the genes (Pa×gINV2 and Pa×gINV3) appearing as a genomic tandem repeat. These genes are more similar to each other than to …
