ASIA-PACIFIC BI TECHNEWS BIOTECHNOLOGY IN INDIA AN INTRODUCTION D. Balasubramanian* iotechnological activities in India can broadly be classified under two B categories — classical and modern. Classical biotechnology mainly refers to areas of biotechnology where tissues and organs, whole plants, organisms It is not commonly and animals are used, while modern biotechnology is largely based on molecular “ and cellular techniques. Classical biotechnology was already in practice effectively by a few universities and national agricultural research institutes in known that the areas India around the 1950s. Scholars trained in the classical disciplines of botany, zoology and agriculture were leading the research activities and indeed some of protoplast fusion, trail-blazing discoveries and developments were made in these universities. It is not commonly known that the areas of protoplast fusion, anther culture and callus culture, as well as micro-propagation using tissue culture of plants got anther culture and its earliest start in India, notably in the department of botany at the University of Delhi. The pioneers in these techniques are Professors Indra Vasil (protoplast callus culture, as well fusion), S. Maheshwari and his student Sipra Guha (callus culture and anther culture), B M Johri and H Y Mohan Ram (micropropagation, promiscuous as micro-propagation flowering of plants). Even as early as the late 1950s, micro-propagation of a variety of plants was successfully achieved in their laboratories. (It is thus notable, but not surprising, that much of the biotechnological activities in using tissue culture of India at present is still pretty much plant-based and is focused on micro- propagation in green houses.) It was around that time that plant geneticists plants got its earliest realized the importance of hybrid seeds, cross varieties, selection breeding and other biotechnological inputs. The Indian Council of Agricultural Research start in India. (ICAR), which predates independent India, had established excellent field stations and research outlets at various places such as Pusa, New Delhi, and Coimbatore. ” *Professor D. Balasubramanian is Director of Research, Hyderabad Eye Research Foundation, L.V. Prasad Eye Institute, Hyderabad, India.

From proportions, which has been carried out successfully a mere 50 million tons output of food grains in the late more than once. The most recent instance has been the 1940s, India now produces 200 million tons — in just a immunization of over 150 million Indian children against matter of slightly more than 50 years. The fact that a nation polio using the oral polio vaccine in a ‘pulsed’ fashion that was forced to import food two generations ago now twice within 60 days. Similarly, the large-scale elimination produces more than its needs and is able to export food of goiter from focal areas through the use of iodized salt grains is testimony to the successful use of biotechnology and the administration of vitamin A doses to school children in agriculture.

Modern biotechnology was introduced in India around Cooperative dairy management involving thousands of the 1970s when a significant number of Indian researchers dairies, proper choice of livestock and milch cattle, an trained in the US and Europe in various aspects of modern efficient people-friendly, and people-participatory biotechnology returned to India.

The DBT not only funds extramural research projects but has also started institutions and centers of excellence in areas of modern biotechnology such as the National Institute of Immunology, National Centre for Cell Sciences, Centre for DNA Fingerprinting and Diagnostics, and the National Centre for Brain Research. It also supports university centers of excellence. The DBT has also prepared guidelines on the use of recombinant DNA techniques, transgenics, and other issues. An important fillip to capacity building in biotechnology in the country has been provided by the DBT through their MSc programs in biotechnology, for which students are chosen on the basis of a national examination, and the DBT postdoctoral research program which supports about a hundred postdoctoral research fellows in four or five centers across the nation. Sponsored projects and grant-in- aid projects also employ postdoctoral researchers. International cooperation in the area of biotechnology has also been possible through the DBT Visiting Associateships and Visiting Fellowships offered to both Indian and overseas scholars.
