Peroxidase-Induced Wilting in Transgenic Tobacco Plants.

Expression of horseradish peroxidase in transgenic tobacco.

Introduction Peroxidases are common oxidoreductases present in plants, animals and micro-organisms. Plant peroxidases are classified as basic, neutral or acidic enzymes, depending on their profiles of elution during ion-exchange column chromatography or isoelectric points [ 11. Horseradish (Amtoru~h rusticuna) peroxidases (HRPs; EC 1.1 1.1.7), are probably the best characterized of these enzyme...

Expression and antimicrobial activity analysis of dermaseptin B1 recombinant peptides in tobacco transgenic plants

Recently, new molecular breeding and genetic engineering approaches have emerged to overcome the limitations of conventional breeding methods in generating disease-resistance transgenic plants. The use of antimicrobial peptides (AMPs) to produce transgenic plants resistant to a wide range of plant pathogens has achieved great success. Among huge number of AMPs, Dermaseptin B1 (DrsB1), an antimi...

Assessment of salt tolerance in transgenic tobacco (Nicotiana tobacum L.) plants expressing the AUX gene

Transformation of plants using Agrabacterium rhizogenes may affect secondary metabolite production as well as morphological changes. In this study, T-DNA from Ri plasmid in A. rhizogenes carrying pRi15834-PRT35S-GUS was introduced into tobacco leaf segments to initiate development of transformed hairy roots. Plant regeneration from transgenic roots used MS medium, and plants regenerated fro...

Amyloid-Like Protein Inclusions in Tobacco Transgenic Plants

The formation of insoluble protein deposits in human tissues is linked to the onset of more than 40 different disorders, ranging from dementia to diabetes. In these diseases, the proteins usually self-assemble into ordered β-sheet enriched aggregates known as amyloid fibrils. Here we study the structure of the inclusions formed by maize transglutaminase (TGZ) in the chloroplasts of tobacco tran...
