Synergistic Action of D-Glucose and Acetosyringone on Agrobacterium Strains for Efficient Dunaliella Transformation.

ABSTRACT: An effective transformation protocol for Dunaliella, a β-carotene producer, was developed using the synergistic mechanism of D-glucose and Acetosyringone on three different Agrobacterium strains (EHA105, GV3101 and LBA4404). In the present study, we investigated the pre-induction of Agrobacterium strains harboring pMDC45 binary vector in TAP media at varying concentrations of D-glucose (5 mM, 10 mM, and 15mM) and 100 μM of Acetosyringone for co-cultivation. Induction of Agrobacterium strains with 10 mM D-glucose and 100 μM Acetosyringone showed higher rates of efficiency compared to other treatments. The presence of GFP and HPT transgenes as a measure of transformation efficiency from the transgenic lines were determined using fluorescent microscopy, PCR, and southern blot analyzes. Highes
