Biotechnology, the use of molecular and cellular tools to genetically modify and improve food supply, will play an increasing and important role in the continuing struggle to produce sufficient food for an ever increasing world population. Many of the approaches will supplement and enhance conventional breeding and also address environmental concerns and help to stabilize food production. This review provides a perspective dealing specifically with crops and three areas of biotechnology, namely, genome analysis with molecular markers, cell- and tissue-culture procedures, and the rapid and precise incorporation of genes via transformation. One must remember that biotechnology is still in its infancy, and that approaches will be greatly improved and more efficiently utilized in the future for the betterment of mankind.Key words: plants, food, hunger, genome analysis, cell culture, genetic transformation.
