Os12g0170400
The rice gene Os12g0170400 was reported as art1 in 20[1] by researchers from Japan.

Annotated Information
Gene Symbol
- Os12g0170400 <=> art1,Osart1
Function
- ART1 encodes a C2H2-type zinc finger transcription factor(for Al resistance transcription factor 1), which specifically regulates the expression of genes related to Al tolerance in rice (Oryza sativa).
- 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.
Mutation
Figure 1. Phenotype of the art1 Mutant. [1].
- There is no difference in the root and shoot morphology between the art1 and its wild type. In the absence of Al, the mutant showed root growth similar to that of the wild type (Figure 1A). However, in the presence of Al, the root elongation of art1 was inhibited significantly more than in the wild type. At 10, 30, and 50 mMAl, root elongation was inhibited by 64, 83, and 88%, respectively, in art1 and was inhibited by 27, 49, and 68%, respectively, in the wild type (Figure 1A). In neutral soil, both lines grew similarly (Figure 1B), while in acid soil, the root growth of art1 was completely inhibited. The wild type and art1 were equally sensitive to a low pH and to other metals, including Cd, La, Zn, and Cu (Figures 1C and 1D).
Expression
- ART1 is constitutively expressed in the root, and the expression level is not affected by Al treatment
Sublocalization
- ART1 is localized in the nucleus of all root cells.
Evolution
- BLAST searches revealed that ART1 has five close homologs in rice.
