Agri-biotechnology and Healthcare GM Crops GM Crop based Products
Global GM crop scenario • Area coverage ~68 million hectare • Market value ~ US$ 5.0 billion • Major crops in commerce: soybean, maize, cotton,canola, tomato, potato, rice • Major traits of interest: insect resistance, viral resistance, herbicide tolerance, drought/salinity tolerance, nutritional quality. • [estimated global bio-pharma market ~US$ 15 b]
Emerging plant-based new ventures other than GM crops • Plant based: r-therapeutics & diagnostics (human & veterinary applications) • Metabolically engineered phytomedicines • Value-added herbal products (new products from known herbs: target new disease/ more knowledge rich)
Important Biotech Healthcare products for molecular farming • 1986: Human growth hormone in tobacco • 1989: IgG in tobacco • 1992: Hepatitis B surface antigen in tobacco • 1992: Alpha amylase in tobacco • 1995: IgA in tobacco • 1997: Avidin in maize • 2001: Vaccine in potato • 2003: Functional antibody in algae • 2005: Human anthrax antibodies in tobacco • It is estimated that by 2010 the market for this segment will touch US$ 100 billion
Commercial Scope: healthcare Biotech products • R-therapeutics & diagnostics: US$ 50b (2005); US$ 200b (2015); • Phytomedicine, nutraceuticals & beauticeuticals: US$ 30b (2005); US$ 60b (2015); • Dietetics food & enzymes: US$ 90b (2005); US$ 250b (2015); • Bioinformatics & embeded systems: US$ 02b (2005); US$ 06b (2015).
Mass propagation industry: Major problems • EOU vs domestic market • High volume low value • High risk on quality control & quarantine aspect • Highly competitive • Secured market based on IP is not possible • Automated production for minimizing cost of production needs huge capital investment
Biotech and Electronics- A Double Helix • The multidisplinary approach to Biotechnology has resulted in new and unique interdisciplinary area in which molecular biology, different branches of engineering, electronics etc have played pivotal role in making products, processes and services of the modern biotechnology within reach. of common man. • From application point of view, like twin strands of a double helix, biotechnology and electronics are joining forces in a technological explosion that will dwarf what will be possible by either one of them. These aspects will be highlighted in the paper
GM Crops 2011 • This is a historical landmark in that it is the first time for more than 160 million hectares of biotech crops to be grown in any one year. In order to appropriately account for the use of two or three "stacked traits", that confer multiple benefits in a single biotech variety, is 15% higher than the estimate of 160 million hectares.
Biotechnology and Developing Countries -Interseted but directly not involved in Modern Biotechnology Have National policy on Biotechnology and research programme; little in-country modern biotechnology Have national policy, research programme and international collaboration Have national policy, modern biotech research programme; storng overseas linkage in public and private sectors
Key Points Biology is in a fundamental revolution as knowledge acquisition is exponential Post genomic pharmaceutical (targeted drugs) are based on • Human genome at the chromosomal level • Advent of computer power • Robotics • New automated models • Nano technologies
Key Points The biotechnology promise • Increase agricultural productivity • Increase pharmaceutical specificity • Reduce hunger • Improve Healthcare This technology will move therapeutic from symptomatic treatment to disease- modifying new medicine
Key Points Gene - environment interaction Through knowledge of genomics and proteomics targeted drugs (not based on Symptoms) can be created.
Key Points The activation of research groups in the south promoted by major research institute based in developed countries by providing stable funding for these groups. This approach could make possible the development of new therapeutic drugs and vaccines designed specifically for LDCs related
Key Points Technology transfer which seems to be a gateway to a new and promising economic development in those countries where a good level of entrepreneurship is already able to promote and produce innovations
Key Points Public awareness has to be promoted to balance fears and opportunities. Each country should be able to sort out the benefits from the hazards of biotechnology; recognizing ethical concern and helping the public make more informed choices. This could help foster international cooperation in biotechnology research
