Complementation tests of Arabidopsis genes in yeast mutants have suggested a role for an iron transporter (4) in plant [Cd.sup.2+] and [Zn.sup.2+] uptake while other work with leaf guard cells suggests a [Cd.sup.2+] and [Zn.sup.2+] permeable Ca2+ channels may be involved (5) but direct tests of root membrane [Cd.sup.2+] and [Zn.sup.2+] transport are lacking.
Complementation tests, including with the nitrate-tolerant super nodulation (NTSN) mutants of R32 for which a gene symbol nts has been assigned previously (Park and Buttery, 1989), revealed that all three nodulation types were under nonallelic control with distinct function.
