Function
This gene has the activity of transcription, and is an important regulatory factor of grasses in the iron reaction, to be responsible for regulation of the key genes involved in Fe absorptionOgoetal.2007;unpublished data. Under iron deficiency conditions, OsIRO2 is an indispensable factor for effective absorption to iron. In plants of OsIRO2 RNAi, due to the expression of OsIRO2 declining, the synthesis of mugineic acid is decreased. Meanwhile, the secretion of 2'-deoxy mugineic acid is reduced, resulting in a decrease of iron absorption, so that the iron content in the plants drops, leaves yellowing and its growth is inhibited. Under conditions of iron deficiency, unknown transcription factor binds into the promoter of iron deficiency OsIRO2 response cis-acting elements (IDE), to adjust the expression of OsIRO2, then OsIRO2 binds to the related gene or promoter sequences which is CACGTGG about iron absorption, regulating the expression of these genes, and promoting the absorption of iron in rice under iron deficiency conditions1.
Expression
In the iron-sufficient conditions, there is no significant difference between the plants of overexpression OsIRO2 and OsIRO2 RNAi and wild type of plants; under iron deficiency conditions, the growth of OsIRO2 RNAi plants is inhibited, their leaves yellowing, while the growth of OsIRO2 overexpression plants can continue, and plant height is higher than that of wild-type and OsIRO2 RNAi plants2.
