14 lut 2022 · During cell expansion, the material properties of the wall, particularly the orientation of the main load-bearing wall component, cellulose microfibrils (CMFs), are thought to be a strong predictor of how much and in what direction cells expand. In “Cell twisting during desiccation reveals axial asymmetry in wall organization,” Keynia et al. (
We propose that deoxyribose is oxidized to deoxyribonate, oxidized to ketodeoxyribonate, and cleaved to acetyl coenzyme A (acetyl-CoA) and glyceryl-CoA. We have genetic evidence for this pathway in three genera of bacteria, and we confirmed the oxidation of deoxyribose to ketodeoxyribonate in vitro.
In this review, we describe efforts to characterize the organization of cellulose in plant cell walls. X-ray scattering reveals the size and orientation of microfibrils; diffraction reveals unit lattice parameters and crystallinity.
4 sie 2023 · In biological samples, cell walls/shapes/tissues are discretized and represented as an interconnected mesh of nodes and vertices, and their collective behaviour is modelled (Kennaway and Coen, 2019). FEM can incorporate parameters related to cell walls and mechanical forces to predict changes in cell shape or, based on cell morphology, it can ...
The insights gained from the increasingly detailed cell wall imaging procedures and the assessments and the modeling of the physical attributes of intact cell walls are likely to be central to achieving the goal of integrated knowledge of cell wall biology.
1 sty 2021 · In plants, the deoxy sugar l -rhamnose is widely present as rhamnose-containing polymers in cell walls and as part of the decoration of various specialized metabolites.
In this review, we summarize the major advances made in understanding the cell wall in this era of functional genomics, including the latest findings on the biosynthesis, construction, and functions of the cell wall.
