General Information

General Information Comment Organism
physiological function constitutive expression of enzyme gene in tall fescue in the vacuole, apoplast, and Golgi, results in only a small number of plants with low enzyme activities and in reduced plant growth in apoplast, and golgi targeted plants. Constitutive expression in the apoplast also results in increased levels of cell wall bound hydroxycinnamic acid monomers and dimers, but no significant effect on cell wall xylose or arabinose content. In situ constitutive xylanase expression in the Golgi also results in increased ferulate dimers. Senescence-induced xylanase expression in the apoplast is considerably higher and does not affect plant growth or the level of monomeric hydroxycinnamic acids or lignin in the cell walls. These plants also show increased levels of ferulate dimers, and decreased levels of xylose with increased levels of arabinose in their cell walls Trichoderma reesei
