Gene Expression and Iron Accumulation in Progeny of Transformants Introduced Fpl Gene Encoding the Iron Storage Protein in Red Pepper (Capsicum annuum L.)

To improve the iron content of red pepper, we have transferred the entire coding sequence of the ferritin gene(Fp1) into Capsicum annuum (L. cv. Chungyang and Bukang) by Agrobacterium mediated transformation. Transformants were found to contain the Fp1 gene at up to three loci, increased distinct iron content changes. In transgenic plants, iron content was as much as 7-fold to 8-folds greater than that of their untransformed counterparts. Furthermore, the R1 progenies from transformant(A7, A8) co-segregated into a 15:1 ratio for both Kanamycin resistance and genotype of high iron.
