Cell suspension cultures were initated from calli derived from in vitro strawberry leaves on MS medium (Murashige and Skoog, 1962) supplemented with 30 g/l sucrose, 1.0 mg/l 2,4-D and 0.3 mg/l kinetin. There were many factors affected on cell suspension cultures growth (it was found that ). Cell suspension cultures grew better on MS medium with ...

SUMMARY In order to develop live attenuated vaccine against Aeromonas hydrophila infection in fish, Aeromonas hydrophila mutant strain was created by knocking out the aroA gene, encoding 5-enolpyruvylshikimate 3- phosphate synthase. A 683 bp middle fragment of this gene was replaced by kanamycin resistance gene KmR to make the cassette aroA::Km...

Expression of HIV-1 p24 gene in chloroplasts was achieved in a tobacco variety V2 (Virginia TBE2). Through PCR and Southern blot analyses, it was demonstrated that the transgene integrated into the target site in the chloroplasts, between trnfM and trnG. Western blot results showed that HIV-1 p24 gene expressed in transplastomic tobacco plants. ...

Diabetes is one of the diseases, which have recently gained significant attention. In order to produce the recombinant insulin for treating diabetics, we have cloned and expressed a miniproinsulin in Pichia pastoris. The DNA fragment containing a gene encoding the fusion protein of miniproinsulin-6xhis was cloned into the integrative plasmid pPIC...
