Expression data from tobacco expressing 35S-AtHMA4 compared to the wild-type plants grown in the presence of Cd


ABSTRACT: Cd levels in the shoots, as well as in the roots were unexpectedly reduced in 35S:AtHMA4-expressing tobacco. Obtained results indicate that in the generation of the Cd-related phenotypes of transgenic plants substantial modifications of the host plant transcriptome was involved. Microarray based analysis was performed to compare expression profiles of the roots from tobacco expressing 35S-AtHMA4 with the wild-type (WT) plants, which were grown in the presence of 0.25 µM Cd. An effort was undertaken to understand which processes were modified in tobacco as a result of the expression of 35S:AtHMA4, which lead to decreased Cd uptake and lower accumulation in the shoots. Knowing underlying mechanisms is important for developing strategies to grow low cadmium tobacco.
