- ... The ability of Thlaspi goesingense Halacsy to hyperaccumulate Ni appears to be governed by its extraordinary degree of Ni tolerance. However, the physiological basis of this tolerance mechanism is unknown. We have investigated the role of vacuolar compartmentalization and chelation in this Ni tolerance. A direct comparison of Ni contents of vacuoles from leaves of T. goesingense and from the non-t ...

- ... We have characterized two isoforms of ATP-phosphoribosyl transferase (ATP-PRT) from Arabidopsis (AtATP-PRT1 [accession no. AB025251] and AtATP-PRT2), catalyzing the first step of the pathway of hisidine (His) biosynthesis. The primary structures deduced from AtATP-PRT1 and AtATP-PRT2 cDNAs share an overall amino acid identity of 74.6% and contain N-terminal chloroplast transit peptide sequences. D ...
