Differential expression of gene in iron-efficient wheat cultivar Jing411 and iron-inefficient cul-tivar Sanshumai3 under iron-deficiency and iron-sufficiency conditions was revealed by differential display re-verse transcript PCR (DDRT-PCR) method. Northern blotting was carried out using ATP-binding transporter(ABC) cDNA obtained from DDRT-PCR products of the cuitivar Jing411 as probe. Our results suggested thatABC gene expression was suppressed under iron-deficiency condition.
