Expression cassettes containing a duplicated cauliflower mosaic virus (CaMV) 35S promoter fused to a polylinker preceded by the CCACCATGG and AACAATGG sequences were constructed. These two sequences correspond to the consensus sequences around the translation start codons in vertebrates and plants respectively. Translational fusions were made with the(More)
The sulfonamide resistance gene from plasmid R46 encodes for a mutated dihydropteroate synthase insensitive to inhibition by sulfonamides. Its coding sequence was fused to the pea ribulose bisphosphate carboxylase/oxygenase transit peptide sequence. Incubation of isolated chloroplasts with the fusion protein synthesised in vitro, showed that the bacterial(More)
Voacanga Africana stapf (Apocynaceae) leaves is being used in herbal medicine to treat leprosy, diarrhoea, generalized oedema and convulsion in children as an infant tonic and the present study was aimed at its toxicological evaluation in wistar rats. The sub-acute toxicity was evaluated after administering daily oral doses of Voacanga Africana stapf (100,(More)
