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”
