Abstract

Environmental stresses and iron limitation are the primary causes of crop losses worldwide. Engineering strategies aimed at gaining stress tolerance have focused on overexpression of endogenous genes belonging to molecular networks for stress perception or responses. Based on the typical response of photosynthetic microorganisms to stress, an alternative approach has been recently applied with considerable success. Ferredoxin, a stress-sensitive target, was replaced in tobacco chloroplasts by an isofunctional protein, a cyanobacterial flavodoxin, which is absent in plants. Resulting transgenic lines showed wide-range tolerance to drought, chilling, oxidants, heat and iron starvation. The survival of plants under such adverse conditions would be an enormous agricultural advantage and makes this novel strategy a potentially powerful biotechnological tool for the generation of multiple-tolerant crops in the near future.

摘要

环境胁迫和铁限制是全球作物减产的主要原因。旨在提高胁迫耐受性的工程策略主要集中在过表达属于胁迫感知或反应分子网络的内源基因上。基于光合微生物对胁迫的典型反应,最近采用了一种替代方法并取得了相当大的成功。铁氧还蛋白是一种对胁迫敏感的靶标,在烟草叶绿体中被一种植物中不存在的同功能蛋白——蓝细菌黄素氧还蛋白所取代。由此产生的转基因品系对干旱、低温、氧化剂、高温和铁饥饿表现出广泛的耐受性。植物在这种不利条件下的存活将是一项巨大的农业优势,并使这种新策略成为在不久的将来培育多耐受性作物的一种潜在强大的生物技术工具。
