Abstract

Fig is one of the most important fruit trees in Egypt. It used to constitute the major source of income for the inhabitants of the western north coast of Egypt. Since 1993 fig cultivations were threatened by a number of factors including virus, insect and mite infections. An efficient system for regeneration and transformation of the common fig Ficus carica L. cultivar Sultani (fresh consumption) was required to conserve fig cultivation in the area. The effect of different combinations of BA and NAA/2,4-D and kinetin on callus formation from leaf segments were studied. Results showed that the best medium for callus formation was MS supplemented with 2.0 mg/l 2,4-D and 0.2 mg/l kinetin. The best plantlet differentiation was obtained at concentrations of 30 mg/l 2iP and 7 mg/l TDZ with 0.25 mg/l NAA (with a regeneration efficiency of 83 and 79%, respectively). On the other hand, the obtained callus failed to induce organogenesis on media containing a combination of BA and kinetin. The highest shoot formation percentage (89%) was obtained when using 2 mg/l TDZ and 4 mg/l 2iP. The highest percentage of shoots forming roots (95%) was obtained when using MS medium supplemented with 1.0 mg/l IBA. Explants were transformed using Agrobacterium and microprojectile bombardment using the plasmid pISV2678 which harbors the gus-intron and bar genes. Results showed that the highest transformation efficiency using the Agrobacterium (17.5%) was obtained when explants were co-cultivated with the bacteria for 30 min. The highest transformation efficiency recorded using the microprojectile bombardment (12%) was obtained with 2.0 μg DNA per shot at 1,100 psi and a distance of 6 cm repeated twice. The transgenic nature of regenerated plants was confirmed by PCR analysis, histochemical GUS assay and leaf painting assay.
