Boron and zinc uptake of cucurbits — Field test and in silico approach

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.
