Monografia naukowa prezentująca wyniki dziesięcioletnich badań nad wpływem ołowiu i innych metali ciężkich (Cu, Cd, Zn) oraz pewnych stresów abiotycznych (stres solny, osmotyczny, stres wodny) na indukcję syntezy i wzrostu akumulacji polipeptydów o masie cząsteczkowej 16 kDa w siewkach łubinu żółtego. Autor podejmuje także próbę wyjaśnienia mechanizmu aktywacji syntezy białek PRL1-L6 oraz ich biologicznej funkcji.
Heavy metal ions, such as Pb2+, Cu2+, Cd2+, Zn2+ as well as some other abiotic factors, induce in lupin seedlings the synthesis and accumulation of 6 polypeptides of molecular weight 16 kDa, designated as PR(L1-L6). The sequence analysis of N-terminal amino acids indicated that all polypeptides composing the 16 kDa fraction show a high degree of homology to the PR-10 family of pathogenesis-related proteins as well as to RNase from ginseng callus and to the tree pollen allergens. Within the fast migrating form of 16 kDa polypeptides the presence of a subunit of cytosolic Cu:Zn-superoxide dismutase (SOD) was detected. The presence of PR(L1-L6) proteins were observed, by tissue-printing method, in all organs of lupine seedlings. The lead ions causes the enhancement of PR(L1-L6) accumulation within parenchymatic cells of rout cortex, hypocotyl and stem. The immuno-gold analysis have shown the intracellular, cytoplasmic localization of PR(Ll-L6) proteins.
