Description	Ultraviolet-B radiation (UV-B, wavelength 280-315 nm) is a clastogen (chromosome-breaking factor) that has accompanied life on Earth throughout its entire history (Lomax, 2012). Plants need to cope with UV-B almost permanently, as they are sessile organisms whose survival is directly dependent on solar radiation. The susceptibility to clastogens may depend on the type of chromosomes (Zedek and Bureš, 2018).
