Summary
Callose, a matrix component in plant cell walls, is crucial for stomatal function. This review highlights callose
Area of Science:
- Plant Biology
- Cell Biology
- Plant Physiology
Background:
- Cellulose microfibrils are key to guard cell (GC) wall function in stomata.
- Matrix materials, particularly callose, also significantly influence stomatal mechanisms.
- Callose actively participates in the opening and closure of stomatal pores in fern stomata.
Purpose of the Study:
- To review and discuss recent findings on callose distribution and function in plant stomata.
- To compare the role of callose in different types of stomata (kidney-shaped vs. dumbbell-shaped).
Main Methods:
- Review of recent scientific literature on stomatal cell wall composition and function.
- Comparative analysis of callose's role in dicotyledonous (Vigna sinensis) and monocotyledonous (Zea mays) stomata.
Main Results:
- Callose is present and functionally important in kidney-shaped stomata of Asplenium nidus.
- The review examines callose in Vigna sinensis (dicot) and Zea mays (monocot) stomata.
- Callose's distribution and specific roles in stomatal function are discussed.
Conclusions:
- Callose plays a significant role in the formation and function of stomatal pores.
- Callose influences stomatal pore mechanics by altering the properties of guard cell walls.
- These findings apply to both kidney-shaped and dumbbell-shaped angiosperm stomata.

Cellulose and Pectic Polysaccharides
4.1K
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...

Regulation of Transpiration by Stomata
29.5K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Adaptations that Reduce Water Loss
27.0K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Cell Adhesion in Plants
2.9K
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,...

C4 Pathway and CAM
47.2K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.
