Biotechnology is the controlled engineering of plants suing in vitro methods. As a technology, it is competent to meet the challenge for the increased turnover of biomass for the energy production. The world's demand for food, shelter and wood is expected to double by 2030. Hence, a large scale propagation and rapid multiplication of short duration plants, synthesis of novel, disease resistant, high yielding, disease free and photosynthetically efficient ...
