Plant architecture, auxin homeostasis and phenol content in Arabidopsis thaliana grown in cadmium- and zinc-enriched media
A screening strategy using micropropagation glass tubes with a gradient of distances between germinating seeds
and a metal-contaminated medium was used for studying alterations in root architecture and morphology of
Arabidopsis thaliana treated with cadmium (Cd) and zinc (Zn) at the concentration of 10–20 ?M and 100–200 ?M,
respectively. Metal concentrations in plant shoots and roots were measured by quadrupole inductively coupled
plasma mass spectrometry. After 21 days from germination, all plants in the tubes were scanned at high resolution
