Abiotic stress conditions are the major limitations in modern agriculture. Although many genes associated with plant response(s) to abiotic stresses have been indentified and used to generate stress tolerant plants, the success in producing stress-tolerant crops is limited. New technologies are providing opportunities to generate stress tolerant crops. Biotechnological approaches that emphasize the development of transgenic crops under conditions that mimic the field situation and focus on the plant reproductive stage will significantly improve the opportunities of producing stress tolerant crops. Here, we highlight recent advances and discuss the limitations that hinder the fast integration of transgenic crops into agriculture and suggest possible research directions. This article is part of a Special Issue entitled: Plant gene regulation in response to abiotic stress.
非生物胁迫条件是现代农业中的主要限制因素。尽管已经鉴定出许多与植物对非生物胁迫的反应相关的基因，并用于培育耐胁迫植物，但培育耐胁迫作物的成功案例有限。新技术为培育耐胁迫作物提供了机会。强调在模拟田间条件下培育转基因作物并关注植物生殖阶段的生物技术方法，将显著提高培育耐胁迫作物的机会。在此，我们重点介绍了近期的进展，并讨论了阻碍转基因作物快速融入农业的限制因素，并提出了可能的研究方向。本文是名为“植物对非生物胁迫的基因调控”的特刊的一部分。
