GM Crops. 2010 Mar-Apr;1(2):68-79. doi: 10.4161/gmcr.1.2.11877.
Post-green revolution advances made in biotechnology paved the way of cultivating the high-yielding, stress and disease resistant genetically modified (GM) varieties of wheat, rice, maize cotton and several other crops. The recent rapid commercialization of the genetically modified crops in Asia, Americas and Australia indicates the potentiality of this new technology. GM crops give higher yields and are rich in nutritional values containing vitamins and minerals and can thus can help to alleviate hunger and malnutrition of the growing population in the under developed and developing countries. It could also be possible to develop more biotic and abiotic stress resistant genotypes in these crops where it was difficult to develop due to the unavailability of genes of resistance in the crossing germplasms. However, further research and investigations are needed to popularize the cultivation of these crops in different parts of the world. This review provides an insight of the impact of GM crops on contemporary agriculture across the past few decades, traces its' history across time, highlights new achievements and breakthroughs and discusses the future implication of this powerful technology in the coming few decades.
绿色革命后生物技术取得的进展为培育高产、抗逆和抗病的转基因小麦、水稻、玉米、棉花及其他几种作物品种铺平了道路。近期转基因作物在亚洲、美洲和澳大利亚迅速商业化，显示了这项新技术的潜力。转基因作物产量更高，富含维生素和矿物质等营养价值，因此有助于缓解欠发达国家和发展中国家不断增长的人口的饥饿和营养不良问题。在杂交种质中由于缺乏抗性基因而难以培育出更多抗生物和非生物胁迫基因型的作物中，也有可能培育出这样的基因型。然而，需要进一步的研究和调查，以便在世界不同地区推广这些作物的种植。本综述深入探讨了转基因作物在过去几十年对当代农业的影响，追溯了其随时间的发展历程，突出了新成就和突破，并讨论了这项强大技术在未来几十年的潜在影响。
