DNA under attack: How plants deal with and repair genetic damage.
Article Sidebar
Main Article Content
Abstract
Plants are resilient organisms that have developed multiple mechanisms that allow them to cope with the environmental conditions of their surroundings. Many of these mechanisms focus on the perception and repair of genetic material, which contains all the information necessary for an organism's life.
This article illustrates how plants respond to genetic damage caused by factors such as UV radiation, reactive oxygen species and pollutants. Focus is put on describing the DNA repair mechanisms plants have developed. Additionally, it explores the evolutionary significance of these processes and their application in crop genetic improvement. Conclusion is centered in highlighting the potential of these strategies to achieve more resilient agriculture.
