Production of pharmaceutical glycoproteins, such as therapeutic antibodies and cytokines, in plants has many advantages in safety and reduced costs. However, plant-made glycoproteins have N-glycans with plant-specific sugar residues (core β-1,2-xylose and α-1,3-fucose) and a Lewis a (Le(a)) epitope,
GDP-D-mannose pyrophosphorylase (GMP) is an important enzyme in the Smirnoff-Wheeler's pathway for the biosynthesis of ascorbic acid (AsA) in plants. We have reported recently that the expression of the acerola (Malpighia glabra) GMP gene, designated MgGMP, correlates with the AsA content of the
Plant viruses cause devastating diseases in plants, yet no effective viricide is available for agricultural application. We screened cultured filtrates derived from various soil microorganisms cultured in vegetable broth that enhanced plant viral resistance. A cultured filtrate, designated F8
Tobacco (Nicotiana tabacum L.) cells were cultured in a liquid medium which contained sucrose as a source of carbon and energy. Various cell-wall constituents and wall precursors (L-arabinose, D-xylose, D-galactose, D-mannose, D-glucuronate, myo-inositol) were added to cells growing in this medium
BACKGROUND
Although plants are the main source of vitamin C in the human diet, we still have a limited understanding of how plants synthesise L-ascorbic acid (AsA) and what regulates its concentration in different plant tissues. In particular, the enormous variability in the vitamin C content of
Vacuoles isolated from Nicotiana rustica var brasilia have been shown to contain significant levels of glycosidase activity when assayed using p-nitrophenyl-glycosides as substrates. The substrate specificity for the glycosidases in the vacuolar fraction closely paralleled that found in the
Experiments were conducted in which d-mannose was supplied to mature Beta vulgaris L. (sugar beet) leaves, via the transpiration stream, to perturb photosynthetic carbon allocation by sequestering cytosolic Pi. Biochemical and enzymic analyses conducted on this tissue indicated that mannose 6-P was
Production of pharmaceutical glycoproteins in plants has many advantages in terms of safety and reduced costs. However, plant-produced glycoproteins have N-glycans with plant-specific sugar residues (core β-1,2-xylose and α-1,3-fucose) and a Lewis a (Le(a) ) epitope, i.e.,
The phytohormone ethylene plays a crucial role in the production and accumulation of reactive oxygen species (ROS) in plants under stress conditions. Ethylene response factors (ERFs) are important ethylene-signaling regulators functioning in plant defense responses against biotic and abiotic
