	The expression pattern of OsSPR1 was determined usingt he GUS gene driven by the OsSPR1 promoter transferred into wild-type plants. GUS staining in transgenic plants indicated that OsSPR1 was ubiquitously expressed in all plant organs, including the root, leaf, stem and spikelet (Fig. 3a–r). OsSPR1 was expressed in primary and lateral roots, both in mature regions and in root tips. Strong expression was observed in the root tip (in the meristem and lateral root initiation regions), where dividing cells are present. The expression of OsSPR1 in the root is mainly associated with vascular tissues (Fig. 3b,d,h). Semiquantitative RT-PCR analysis using SPR1-specific primers showed that SPR1 was expressed at relatively similar levelsin all tissues, including the root, stem base, stem, leaf and panicles (Fig. 3s), consistent with the GUS staining patterns observed.

	OsSPR1 was identified by map-based cloning. It encodes a novel mitochondrial protein with the Armadillo-like repeat domain. Osspr1 mutants exhibited decreased root cell elongation. The large reduction of Fe content observed in the leaves but not the roots of Osspr1 mutant plants under Fe(II) and Fe(III) nutrient supply, and the normal Fe deficiency response for both strategy I and II marker genes in the leaves but not the roots indicate a defect in Fe homeostasis. In addition, root development was also compromised in Osspr1 mutant plants. It is likely that the defective roots of Osspr1 plants will have a secondary effect on nutrient uptake. However, if reduced Fe uptake as a result of damaged roots was the primary reason for the reduced Fe content in the leaves, the Fe content and the Fe deficiency response would have been duced and activated, respectively, in the roots. However, the Fe content in roots of Osspr1 mutant plants was similar to that of wild-type plants (Fig. 6e). Also, no Fe deficiency response was observed in roots (Fig. 7). However, a lower Fe content was observed in the mutant leaves, which was inconsistent with the induction of Fe-responsive genes (Figs 6c, 7). These results indicate that OsSPR1 plays a role in maintaining Fe (and other metal) homeostasis between roots and leaves.		OsSPR1 was identified by map-based cloning.

However, the Fe content in roots of Osspr1 mutant plants was similar to that of wild-type plants (Fig. 6e). Also, no Fe deficiency response was observed in roots (Fig. 7). However, a lower Fe content was observed in the mutant leaves, which was inconsistent with the induction of Fe-responsive genes (Figs 6c, 7). These results indicate that OsSPR1 plays a role in maintaining Fe (and other metal) homeostasis between roots and leaves.
+OsSPR1 was identified by map-based cloning. It encodes a novel mitochondrial protein with the Armadillo-like repeat domain. Osspr1 mutants exhibited decreased root cell elongation. The large reduction of Fe content observed in the leaves but not the roots of Osspr1 mutant plants under Fe(II) and Fe(III) nutrient supply, and the normal Fe deficiency response for both strategy I and II marker genes in the leaves but not the roots indicate a defect in Fe homeostasis. In addition, root development was also compromised in Osspr1 mutant plants. It is likely that the defective roots of Osspr1 plants will have a secondary effect on nutrient uptake. However, if reduced Fe uptake as a result of damaged roots was the primary reason for the reduced Fe content in the leaves, the Fe content and the Fe deficiency response would have been duced and activated, respectively, in the roots. However, the Fe content in roots of Osspr1 mutant plants was similar to that of wild-type plants (Fig. 6e). Also, no Fe deficiency response was observed in roots (Fig. 7).
