| Abstract: | A new member of the sulphate transporter gene in
Arabidopsis encoding a chloroplast-localizing isoform,
AST82 (accession no. AB008782) has been identified.
AST82 had a sequence similarity with a cyanobacterial
genome sequence, slr1776, which encodes a putative
eukaryotic proton/sulphate co-transporter. Fusion proteins of
AST82 and green fluorescent protein (GFP) transiently
expressed in Arabidopsis leaves localized in
chloroplasts, indicating that AST82 encodes a
chloroplastic isoform. |
