A gene from pea (<i>Pisum sativum</i> L.) with homology to metallothionein genes

Abstract

While searching for 'organ-specific' genes in pea (Pisum sativum L.) we have isolated a gene (designated PsMTA) which has an ORF encoding a predicted protein with some similarity to metallothioneins (MTs). The PsMTA transcript is abundant in roots which have not been exposed to elevated concentrations of trace metals.
