Abstract
After pre-culture and treatment of osmosis,
zygotic embryos of peanut (Arachis hypogaea L.)
were transformed via particle bombardment with a
plasmid containing a Bluetongue VP2 gene (BTVP2)
comprising neutralizing epitopes. Selection for
Kanamycin resistant calluses and somatic embryos
was initiated at 12th day post-bombardment on
medium containing 25 mg/L Kanamycin. Under
continuous selection, 12.38% Kanamycin resistant
plantlets were regenerated from bombarded somatic
embryos. The presence and integration of BTVP2 DNA
in regenerated Kanamycin resistant plants were
confirmed by southern hybridization assay using
non-radioactive Digoxiginin BTVP2 probe. beta -
Glucuronidase (GUS) enzyme activity was detected
in transgenic somatic embryos but not from
control, non-transformed embryos. The expression
of the BTVP2 protein was confirmed through RT-PCR
(reverse transcription polymerase chain reaction)
using the RNA isolated from the transgenic callus
employing BTVP2- specific primers. The production
of transgenic peanut was mainly focused on
evaluating a newly improved somatic embryogenesis
regeneration system as well as the gene transfer
method and to produce the Bluetongue outer coat
protein that comprises the neutralizing epitopes.
