| 英文摘要 | Iron (Fe) is one of the essential mineral elements for plant growth and development. Acquisition of Fe by plants is mediated by a complex network involving Fe mobilization, uptake by root cells, and transport within plants. Here, we evaluated the role of a previously clarified gene encoding a receptor-like protein from rice, OsRMC, in the regulation of Fe acquisition by comparing Fe concentration, biomass, and expression patterns of genes associated with Fe mobilization and transport in wild-type (WT) rice with those in OsRMC overexpression and RNA interference (RNAi) knockdown transgenic rice plants. Expression of OsRMC was upregulated in both shoots and roots upon exposure of WT to Fe-deficient medium. Expression levels of OsRMC were positively correlated with Fe concentration in rice plants under both Fe-sufficient and Fe-deficient conditions such that overexpression and RNAi lines had higher and lower Fe concentration in both roots and shoots than WT plants, respectively. Moreover, overexpression of OsRMC conferred greater accumulation of Fe in mature seeds under Fe-sufficient conditions. OsRMC may also play a role in regulation of Fe deficiency-induced changes in root growth, as evidenced by greater and smaller root systems of OsRMC overexpression lines and RNAi lines than WT under Fe-deficient conditions, respectively. Several Fe deficiency-responsive genes including OsDMAS1, OsNAS1, OsNAS2, OsNAAT1, OsIRT1, OsYSL15, and OsIRO2 were up- and downregulated in OsRMC-overexpressing and RNAi plants compared with WT rice plants. These novel findings highlight an important role of OsRMC played in mediation of Fe acquisition and root growth in rice, particularly under Fe-deficient conditions. |
