Figure 1From: Ectopic expression of MdSPDS1 in sweet orange (Citrus sinensis Osbeck) reduces canker susceptibility: involvement of H2O2 production and transcriptional alterationRegeneration of transgenic plants from 'Anliucheng' embryogenic callus infected with Agrobaterium tumefaciens containing MdSPDS1 gene. (A) Selection of the callus on kanamycin-containing medium. (B) Induction of embryoids from the callus that survived after several rounds of selection. (C) Regeneration of multiple shoots from cotyledonary embryoids. (D) Wild type (left) and a transgenic line (TG9, right) grown in a soil pot.Back to article page
