Expression data from root tissues of 35S:AtHMA4 and wild-type tomato plants grown in the presence of Zn


ABSTRACT: Ectopic expression of AtHMA4 in tomato modified Zn accumulation in a Zn-supply dependent manner. It suggests that HMA4-expression under a range of Zn-supply differentially modifies the expression of endogens, which contributes to different Zn-related phenotypes. To identify genes differentially regulated in 35S:AtHMA4-expressing and wild-type tomato, the transcription profiles were compared between roots of transgenic and WT-plants grown in the presence of 5 µM Zn. An effort was undertaken to recognize tissue specific alterations underlying the difference in Zn root:shoot distribution between tested plant lines and LCM technique was used to isolate epidermis+cortex and stele from roots.Understanding the interplay between the transgene and the endogens is crucial for planning genetic modification for Zn-biofortification purpose.
