The purpose of this research was Eucalyptus saligna in vitro regeneration and transformation with P5CSF129A gene, which encodes Δ1-pyrroline-5-carboxylate synthetase (P5CS), the key enzyme in proline biosynthesis. After selection of the most responsive genotype, shoot organogenesis was induced on leaf explants cultured on a callus induction medium (CI) followed by subculture on a shoot induction medium (SI). Shoots were subsequently cultured on an elongation medium (BE), then transferred to a rooting medium and finally transplanted to pots and acclimatized in a greenhouse. For genetic transformation, a binary vector carrying P5CSF129A and uidA genes, both under control of the 35SCaMV promoter, was used. Leaves were co-cultured with Agrobacterium tumefaciens in the dark on CI medium for 5 d. The explants were transferred to the selective callogenesis inducing medium (SCI) containing kanamycin and cefotaxime. Calli developed shoots that were cultured on an elongation medium for 14 d and finally multiplied. The presence of the transgene in the plant genome was demonstrated by PCR and confirmed by Southern blot analysis. Proline content in the leaves was four times higher in transformed than in untransformed plants while the proline content in the roots was similar in both types of plants. |
