- Information
- Symbol: STAR1
- MSU: LOC_Os06g48060
- RAPdb: Os06g0695800
- Publication
- Genbank accession number
- Key message
- A yeast one-hybrid assay showed that ART1 has a transcriptional activation potential and interacts with the promoter region of STAR1, an important factor in rice Al tolerance
- Microarray analysis revealed 31 downstream transcripts regulated by ART1, including STAR1 and 2 and a couple of homologs of Al tolerance genes in other plants
- Both STAR1 and STAR2 are expressed mainly in the roots and are specifically induced by Al exposure
- Expression in onion epidermal cells, rice protoplasts, and yeast showed that STAR1 interacts with STAR2 to form a complex that localizes to the vesicle membranes of all root cells, except for those in the epidermal layer of the mature zone
- Furthermore, addition of exogenous UDP-glucose rescued root growth in the star1 mutant exposed to Al
- Here, we report that two genes, STAR1 (for sensitive to Al rhizotoxicity1) and STAR2, are responsible for Al tolerance in rice
- STAR1 encodes a nucleotide binding domain, while STAR2 encodes a transmembrane domain, of a bacterial-type ATP binding cassette (ABC) transporter
- These results indicate that STAR1 and STAR2 form a complex that functions as an ABC transporter, which is required for detoxification of Al in rice
