Summary
Phtheirospermum japonicum utilizes PjPME and PjPMEI genes to modify cell walls during haustoria development in host plants. The precise interaction and balance of these proteins during this process are not yet fully understood.
Area of Science:
- Plant biology
- Molecular biology
- Biochemistry
Background:
- Phtheirospermum japonicum is a parasitic plant that invades host plants through specialized structures called haustoria.
- Plant cell wall modification is crucial for successful haustorial development and parasitism.
Purpose of the Study:
- To investigate the role of PjPME and PjPMEI genes in haustoria development in Phtheirospermum japonicum.
- To understand the modulation of cell walls during plant parasitism.
Main Methods:
- Gene expression analysis of PjPME and PjPMEI during haustoria development in rice and Arabidopsis.
- Assay of PME activity in relation to haustoria development.
Main Results:
- Induced expression of PjPME and PjPMEI genes was observed during haustoria development.
- Increased PME activity was detected, correlating with cell wall modulation.
- The study highlights the involvement of PME and PMEI in altering the host cell wall.
Conclusions:
- PjPME and PjPMEI genes play a role in haustoria development and cell wall modification in Phtheirospermum japonicum.
- The interaction and balance of PME and PMEI proteins during haustoria development require further investigation.

3.6K
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...

13.1K
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

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,...

01:02Role of Microtubules in Cell Wall Deposition
2.4K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...
