Function
OsMGT1 is a transporter for Mg uptake in the roots and that up-regulation of this gene is required for conferring Al tolerance in rice by increasing Mg concentration in the cell.
Expression
1 Sequence Analysis of OsMGT1 in Rice
OsMGT1 (Os01g0869200) cloned from rice (cv Nipponbare) contains six exons and five introns (Supplemental Fig. S1A), encoding a peptide of 418 amino acids. Using the SOSUI program (http://bp.nuap.nagoya-u.ac.jp/sosui/), it has been predicted that OsMGT1 is a membrane protein with two transmembrane domains near the C terminus (Supplemental Fig. S1B). OsMGT1 showed the similarity ranging from 63% to 81% to Arabidopsis Mg transporter AtMGT family at the amino acid level. Like other Arabidopsis members, there is a conserved Gly-Met-Asn tripeptide motif at the end of the first transmembrane (domain.http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425201/bin/PP_199778_LW_f1.gif) 
2 Expression Pattern of OsMGT1
Real-time reverse transcription (RT)-PCR analysis revealed that OsMGT1 was expressed in both the shoots and roots at similar level in the absence of Al . However, in the presence of Al, the expression in the roots was up-regulated by 5 times, but that in the shoots was unaffected. Root spatial analysis showed that OsMGT1 was expressed in both the root tips (0–1 cm) and mature region (1–2 cm) and the expression in both regions were up-regulated by Al. However, in art1 (a mutant defective in the Al response C2H2-type zinc-finger transcription factor), the Al-induced expression was not observed , confirming that OsMGT1 expression was regulated by ART1.(http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425201/figure/fig2/)File:Example123456.jpg
3 Sub-cellular Localization of OsMGT1
The subcellular localization of OsMGT1 was investigated in rice protoplasts by transiently expressing OsMGT1 fused with GFP at both C terminal and N terminal under the control of 35S promoter. Either construct gave a signal at the plasma membrane , in contrast to GFP alone, which signal was observed in cytosol and nuclei.(http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425201/figure/fig3/)
