abstract = {Cadmium (Cd) of tobacco is a pollutant that is extremely toxic
to the health of humans. Cadmium/zinc-transporting ATPase HMA1 gene has
been characterized to function in the plant cadmium/zinc-transporting. The complete
coding sequence of tobacco cadmium/zinc-transporting ATPase HMA1 gene
was amplified by RT-PCR. The open reading frame of tobacco cadmium/zinc-transporting
ATPase HMA1 gene was 2418 bp which encodes a protein of 805 amino acids.
BLAST analysis revealed that tobacco cadmium/zinc-transporting ATPase HMA1 protein
shares high homology with the cadmium/zinc-transporting ATPase HMA1 of potato
(85%), Lycopersicon esculentum (84%), wine grape (71%), sweet orange
(71%), soybean (69%) and thale cress (68%). Results also showed that tobacco
cadmium/zinc-transporting ATPase HMA1 gene has a closer genetic relationship
with the cadmium/zinc-transporting ATPase HMA1 gene of Lycopersicon
esculentum. Prediction of transmembrane helices showed that tobacco cadmium/zinc-transporting
ATPase HMA1 might be a transmembrane protein. The expression profile was studied
and results indicated that tobacco cadmium/zinc-transporting ATPase HMA1
gene was moderately expressed in root, leaf and stem but hardly expressed in
flower. These results established the primary foundation of utilizing tobacco
cadmium/zinc-transporting ATPase HMA1 gene to descrease the cadmium content
of tobacco and benefit the health of humans in the future.}
