Influence of UV-B radiation on cytophysiological responces in plants

Cytology and Genetics 2003, v 37, number 6, 66-77

Solar UV-B radiation reaching the Earth’s surface is continually increased due to the stratospheric ozone layer depletion. UV-B radiation has been shown to have mutagenic effects damaging DNA, proteins and membranes. During evolution plants developed systems for UV-B perception and effective defense mechanisms. In this review the main UV-B effects, cytophysiological responses of plants and their interactions with microorganisms are analyzed. UV-B-induced signal transduction pathways in plant cells are discussed.
