Total mineral uptake capacity of zucchini (Cucurbita pepo L. cv. giromontiina) grown in an experimental field at Gödöllo was studied. The mineral content of the soil (brown acidic sandy forest soil) showed unexpectedly high content (mg kg-1 DW) of Ba (95.5), Cr (32.9), Ni (27.8), Pb (15.4) and Zn (53.3). Boron (B) concentration of the soil was relatively low (7.1 mg kg-1 DW), but its bioaccumulation content in root, (2.5) shoot, (33.1) and leaf (50.1) tissues of the plant (mg kg -1 DW). Zinc (Zn) was also bioaccumulated in the plant with contents (mg kg-1 DW) of 47.1 (roots), 23.0 (shoots) and 56.1 (leaves) as compared with 53.3 (in the soil). Toxic element exclusion was observed in zucchini (mg kg-1 DW) concerning Ba (29.0), Co (0.2), Cr (5.3), Ni (5.8) and Pb (3.4) measured in the roots when compared with their concentrations in the soil: Ba (95.5), Co (10.2), Cr (32.9), Ni (27.8) and Pb (15.4). In silico sequence analyses of nucleotide and amino acid sequences of aquaporins (NIP, TIP, SIP and Si-TRP), boron-exporters (BOR), and rbcL of cpDNA revealed plant species with high sequence similarities to the sequences of Cucurbits, which predicted additional plants with intensive mineral (B and Zn) uptake capacity, similar to Cucurbits with phytoextraction potential.
