Plantcellwall（Lecture12）
Plant cell walls represent the majority of the terrestrial plants by mass and mainly consist of polysaccharides and lignin. These constituents are considered as an abundant and renewable carbon resource providing great potential for the production of petroleum-displacing biofuels and biochemicals. However,...

The composition of biomass varies naturally depending upon plant species and cell type, including some highly specialized walls that consist mainly of a single component. Progress is being made in understanding the molecular basis of these natural variations in wall composition. This new knowledge will...
Three contain a transmembrane domain and one contains a glycosylphosphatidylinisotol anchor, features suggesting that these proteins may be targeting the oomycete cell wall rather than plant cell walls. The P. ultimum strain studied here could not grow when cellulose was the sole carbon source (...
Due to its own acetyl group and branched chain, hemicellulose lacks a crystal structure to make it easy to hydrolyse [33], but as a component of plant cell walls, hemicellulose interacts with cellulose and cross-linked lignin, which improves the mechanical strength of plants. Therefore, to ...
Conversely, plant tumors do not produce metastases, for two reasons: (1) plant cell walls are inflexible as they consist of cellulose and therefore the tumor cells cannot move, and (2) plants do not have a circulation system like the blood system of animals. Hence, physical removal of ...
The structural integrity of living plant cells heavily relies on the plant cell wall containing a nanofibrous cellulose skeleton. Hence, if synthetic plant cells consist of such a cell wall, they would allow for manipulation into more complex synthetic plant structures. Herein, we have overcome the...
Pectin, any of a group of water-soluble carbohydrate substances that are found in the cell walls and intercellular tissues of certain plants. In the fruits of plants, pectin helps keep the walls of adjacent cells joined together. Immature fruits contain
(i.e.switchgrass,miscanthus,poplar, and willow). It is a promising resource for biorefineries because it is an abundant, low-cost, non-food material. Plant biomass is primarily composed of plant cell walls; about 75% of this material ispolysaccharidesthat are a major source of potential ...
