There are many iron uptake relative genes cloned so far. But the majority of them encode transporter protein, few transcription factors are cloned. TaMER-BP fragment was used as probe for Malus xiaojinensis cDNA library screening and full length MxMYBl gene was obtained. MxMYBl expression was induced by iron. MxMYBl expression was undetectable by RNA gel blot analysis under iron sufficient conditions, it was induced greatly 3 days after being transferred to iron -deficient medium.Atlg70000 is a homologous g...
