Plants genotoxicity as pollution bioindicator in Jordan using comet assay
1Department of Biological Sciences, Yarmouk University, Irbid, Jordan.
Summary
Wild plants in Jordan show varying DNA damage, indicating genotoxicity from heavy metal pollution. The Comet assay proves effective for environmental pollution monitoring using plants as bioindicators.
Area of Science:
- Environmental Science
- Genetics
- Ecotoxicology
Background:
- Wild plants serve as crucial bioindicators of environmental pollution.
- Assessing genotoxicity in plants can reveal the impact of heavy metal contamination.
Purpose of the Study:
- To evaluate genotoxicity in wild plants across Jordan using the Comet assay.
- To identify pollution hotspots and their correlation with heavy metal accumulation in plants.
Main Methods:
- Collection of wild plants from various sites in Jordan.
- Application of the Comet assay to measure DNA damage index and frequency.
- Analysis of heavy metal content in plant tissues and correlation with genotoxicity markers.
Main Results:
- Significant variations in plant DNA damage and lipid peroxidation rates were observed across collection sites.
- Plants from Aqaba back road and Ghour Assaal exhibited higher genotoxicity.
- Elevated levels of heavy metals (Al, Cr, Fe, Cu, Zn, Cd, Pb) were found in plants from polluted areas, correlating with DNA damage.
Conclusions:
- Heavy metal pollution is a significant source of genotoxicity in wild plants.
- The Comet assay in conjunction with plant bioindicators is a feasible tool for environmental pollution assessment.
- This study highlights the utility of plants as diagnostic tools for monitoring pollution impacts.

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

00:53Tonicity in Plants
60.0K
Tonicity describes the capacity of a cell to lose or gain water. It depends on the quantity of solute that does not penetrate the membrane. Tonicity delimits the magnitude and direction of osmosis and results in three possible scenarios that alter the volume of a cell: hypertonicity, hypotonicity, and isotonicity. Due to differences in structure and physiology, tonicity of plant cells is different from that of animal cells in some scenarios.

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.

65.9K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.
