Advantages and
disadvantages of Transgenic plants
Advantages
- Production of new varieties which is not possible by
conventional breeding programmes
- Improved defense against pests and pathogens
- Increased yield as compared to conventional varieties
- Delayed ripening for longer storage
- Increased essential amino acids, protein, minerals and vitamin
content
- Increased response to fertilizer by plants
- Lesser need of chemical pesticides leads to decreased
environmental pollution
- Crop plants can be engineered to reduce allergy causing
chemicals (Eg. reduced HCN in cassava)
- Help to reduce the carbon foot print
- Transgenic technology enable us to bring different useful genes
together in a single plant
Disadvantages
- Chance of horizontal gene transfer Eg. Crop to weed gene flow-
lead to formation of 'Super Weeds'
- Lack of knowledge on the consequences of transgenic crop on
environment and human health
- Disruption of traditional farming practices
- Loss of traditional varieties
- Dominance of multinational biotech companies in the farming and
seed distribution industry
- Presence of marker gene (antibiotic resistant genes)
/non-removal of marker genes in the plant
- Adverse effect on natural biodiversity (Eg pollinating
insects
