Plant Cell Wall02:43

Plant Cell Wall

61.7K
The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Plant Cell Wall

8.8K
Plant cells have a cell wall, a rigid outer covering that protects the cell and provides shape and support. During cell division, a mixture of enzymes, proteins, and glucose molecules is transported via vesicles to the center of the cell. These vesicles continuously fuse and build a cell plate between the dividing cells. As the cell plate matures, new polysaccharides are added to it to form the cell walls of the daughter cells. The predominant polysaccharide in the cell wall is cellulose, made...

Cellulose and Pectic Polysaccharides

5.3K
 Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth.  Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the...

From DNA to Protein03:06

From DNA to Protein

24.4K
The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma, which states that genes specify the sequence of mRNAs, which in turn specify the sequence of amino acids making up all proteins. The decoding of one molecule to another is performed by specific proteins and RNAs. Because the information stored in DNA is so central to cellular function, it makes intuitive sense that the cell would make mRNA copies of this information for protein synthesis...

Cell Adhesion in Plants01:14

Cell Adhesion in Plants

3.6K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

Area of Science:

  • Plant Biology
  • Biochemistry
  • Glycobiology
  • Structural Biology

Background:

  • Biological systems utilize codes to translate information, such as DNA and proteins.
  • Plant cell walls are complex structures with diverse polymers whose assembly principles are not fully understood.
  • Understanding plant cell wall formation is crucial for various applications, including biofuel production and agriculture.

Purpose of the Study:

  • To propose and explore the concept of a 'Glycomic Code' governing plant cell wall architecture.
  • To investigate how monosaccharides and phenylpropanoids act as 'signs' in this code.
  • To understand how this code dictates cell wall structure, properties, and resistance to deconstruction.

Main Methods:

  • Conceptual framework based on 'Code Biology' principles.
  • Analysis of cell wall biosynthesis, structure, and properties.
  • Focus on cell wall hydrolysis as a 'decryption' mechanism for the Glycomic Code.

Main Results:

  • Evidence suggests that monosaccharides and phenylpropanoids encode information within plant cell walls.
  • The fine structure of cell wall polymers influences polysaccharide packing and polymer interactions.
  • These interactions ultimately determine the final cell wall architecture and properties.

Conclusions:

  • A Glycomic Code, analogous to genetic or protein codes, likely exists in plant cell walls.
  • This code provides a framework for understanding the assembly and function of cell wall polymers.
  • Deciphering the Glycomic Code has implications for controlling cell wall deconstruction and engineering plant cell walls.
