What is genetically modified?
GLOBAL STATUS IN GM
GM cropsTomatoesCotton seed oilPotatoesHoneyRiceCheeseDairy productsSquashCornSoybeansSugarcanePapayaMeatTobaccoBt.Brinjal
GM foodFoods that contain an added gene sequence
Foods that have a deleted gene sequence
Animal products from animals fed GM feed
Products produced by GM organisms
GM ISSUES
Environmental hazardsHarm to other organismsGene transfer
Human health riskAllergyAntibiotics
Economic concernsLengthy and costly process
Other invention discourageSuicide gene technology
GM prospects MERITS DEMERITS
• Easing of world hunger• Reduced strain on
nonrenewable resources • Reduced use of pesticides
&herbicides• Improved crop quality• Development of disease
resistant crop, flood resistance crops
• Improve nutritional quality specific nutritional goals
Lack of germ plasm resources for some of the major pest & pathogens of crops
New plant type evolved for higher productivity are more vulnerable to pest & disease
Problems in source gene from wild relatives
Lack of nutritional qualities in major cereals crops
Who makes sure GM food are safe?
conclusionNow a days GM food are very important to worldReduce the time of harvest GM crops increase yields and reduce pesticide useGM will produce super crops that tolerate drought,
resist pests and disease, and provide improved nutritional value
GM crops are “an important tool in the toolbox” to feed the world.
Focal Theme for Science day
“GENETICALLY MODIFIED CROPS
AND FOOD SECRUITY”
