  • Povečano ultravijolično B sevanje - stres za rastline = Enhanced ultraviolet-B radiation - stress for plants
    Gaberščik, Alenka ; Trošt Sedej, Tadeja
    This paper presents targets of UV-B radiation and plant response to enhanced doses. Adaptation to enhanced UV-B radiation is based on the UV-B absorption properties of various plant tissue and the ... efficiency of repair mechanisms. The main targets are nucleic acids, proteins, and membranes. Damage can be caused directly and indirectly. In plants, UV-B radiation induces regulatory mechanisms that result in photomorphogenetic adaptations or leads to the damage of cell structures and to the inhibition of life processes. UV-B influences gene expression, the content of various substances and pigments, processes in cells, and consequently growth and development. The production ofvarious UV-B protective substances and DNA repair mechanisms play a very important role in plant resistance. Plant response depends on the species and its environment. Environmental adaptations and repair mechanisms determine thesuccess of individual species in the ecosystem.
