Plant cell walls.
Cell walls are important features of plant cells that perform a number of essential functions, including providing shape to the many different cell types needed to form the tissues and organs of a plant. Forming the interface between adjacent cells, plant cell walls often play important roles in intercellular communication. Because of their surface location, plant cell walls play an important r...
متن کاملPlant Cell Walls
The cell wall is the strong, outermost layer of a plant cell, located external to the plasma membrane. The cell wall often far outlives the protoplast which synthesized it. In cork, for example, the wall serves its particular biological role (physical protection of a tree trunk) for many years after the death of the protoplast. However, the walls of living cells are not inert ‘boxes’ but comple...
متن کاملPlant cell walls to ethanol.
Conversion of plant cell walls to ethanol constitutes second generation bioethanol production. The process consists of several steps: biomass selection/genetic modification, physiochemical pretreatment, enzymatic saccharification, fermentation and separation. Ultimately, it is desirable to combine as many of the biochemical steps as possible in a single organism to achieve CBP (consolidated bio...
متن کاملDesigning the deconstruction of plant cell walls.
Cell wall architecture plays a key role in the regulation of plant cell growth and differentiation into specific cell types. Gaining genetic control of the amount, composition, and structure of cell walls in different cell types will impact both the quantity and yield of fermentable sugars from biomass for biofuels production. The recalcitrance of plant biomass to degradation is a function of h...
متن کاملExpansive growth of plant cell walls.
The enlargement of plant cell walls is a key determinant of plant morphogenesis. Current models of the cell wall are reviewed with respect to their ability to account for the mechanism of cell wall enlargement. The concept of primary and secondary wall loosening agents is presented, and the possible roles of expansins, xyloglucan endotransglycosylase, endo-1,4-beta-D-glucanase, and wall synthes...
