Definition: Oxychromatin is a chromatin structure that is found in certain species of plants, such as Arabidopsis thaliana and rice. It is characterized by its high levels of methylation, which can cause it to become more reactive and potentially toxic or defective. This is because the methylation of DNA can lead to the formation of heterochromatin, a structure that is often associated with cancerous cells. Oxychromatinic plants are generally considered to be less susceptible to oxidative
