dc.description.abstract | Increasing usage of gold nanoparticles (AuNPs) in different industrial areas inevitably
leads to their release into the environment. Thus, living organisms, including plants, may be exposed
to a direct contact with nanoparticles (NPs). Despite the growing amount of research on this topic,
our knowledge about NPs uptake by plants and their influence on different developmental processes
is still insufficient. The first physical barrier for NPs penetration to the plant body is a cell wall
which protects cytoplasm from external factors and environmental stresses. The absence of a cell wall
may facilitate the internalization of various particles including NPs. Our studies have shown that
AuNPs, independently of their surface charge, did not cross the cell wall of Arabidopsis thaliana (L.)
roots. However, the research carried out with using light and transmission electron microscope
revealed that AuNPs with different surface charge caused diverse changes in the root’s histology
and ultrastructure. Therefore, we verified whether this is only the wall which protects cells against
particles penetration and for this purpose we used protoplasts culture. It has been shown that plasma
membrane (PM) is not a barrier for positively charged (+) AuNPs and negatively charged () AuNPs,
which passage to the cell. | pl_PL |
