 ===Function===
-Among cereal crops, rice is considered the most tolerant toaluminium (Al). However, variability among rice genotypes leads to remarkable differences in the degree of Al tolerance for distinct cultivars. A number of studies have demonstrated that rice plants achieve Al tolerance through an unknown mechanism that is independent of root tip Al exclusion. We have analysed expression changes of the rice ASRgene family as a function of Al treatment. The gene ASR5was differentially regulated in the Al-tolerant ricessp. Japonica cv. Nipponbare. However,ASR expression did not respond to Al exposure in Indica cv. Taim rice roots,which are highly Al sensitive. Transgenic plants carrying RNAi constructs that targeted theASRgenes wereobtained, and increased Al susceptibility was observed in T1 plants. Embryogenic calli of transgenic rice carrying an ASR5-green fluorescent protein fusion revealed that ASR5 was localized in both the nucleus and cytoplasm. Using a proteomic approach to compare non-transformed and ASR-RNAi plants, a total of 41 proteins with contrasting expression patterns were identified. We suggest that the ASR5 protein acts as a transcription factor to regulate the expression of different genes that collectively protect rice

-    Aluminium (Al) is the most abundant metal, accounting for approximately 7% of Earth’s mass. Regardless of its abundance,Al is not considered an essential nutrient; however, it can occasionally stimulate plant growth or induce other desirable effects when present atlow concentrations (Foy1983). Most Al is chelated by ligands or is present in non-toxic forms, such as aluminosilicates or precipitates. Al-induced toxicity can occur through solubilization of Al in soils under highly acidic conditions (pH below 5.0)(Famoso et al. 2010). It has been estimated that approximately 50% of arable land is negatively impacted by Al toxicity that results from acidic soil(Panda,Baluska&Matsumoto 2009). Al toxicity is considered a primary limiting factor in regard to agricultural productivity (Matsumoto 2000) because it inhibits root growth and mineral absorption (Liu & Luan 2001), leading to a stunted root system that negatively impacts the uptake of water and nutrients.There are many potential cellular locations that could be damaged through interaction with Al, including the cell wall, the surface of the plasma membrane, the cytoskeleton and the nucleus (Pandaet al. 2009). For example, it has been demonstrated that Al binds strongly to the cell wall of root epidermal and cortical cells (Delhaize, Ryan & Randall1993). However, some plants are able to tolerate toxic levels of Al in acidic soils. These plants have evolved mechanisms to detoxify Al that is both present internally and externally(Kochian, Pineros & Hoekenga 2005). To achieve internal detoxification, plants accumulate Al inside vacuoles, where it is chelated with organic acids (OA), such as citrate and oxalate (Ma 2007). In contrast, the majority of Al-tolerant plants exclude Al from the root tip by releasing OA at sites of high Al concentration; examples of these acids include malate, citrate and oxalate (Ma, Ryan & Delhaize 2001; Kochian, Hoekenga & Pineros 2004). In species such as sorghum and wheat, the OA–Al complex prevents Al from entering the cell (Sasakiet al. 2004; Magalhaes et al. 2007),which reduces the concentration and potential toxicity of Al at the growing root tip (Ma et al. 2001).
+* '''In situ''' analysis showed that '''''OsAsr1''''' transcript was preferentially accumulated in the leaf mesophyll tissues and parenchyma cells of the palea and lemma.
