PLoS ONE：植入真菌孢子助水稻适应气候变化

Increased Fitness of Rice Plants to Abiotic Stress Via Habitat Adapted Symbiosis: A Strategy for Mitigating Impacts of Climate Change
Abstract
Climate change and catastrophic events have contributed to rice shortages in several regions due to decreased water availability and soil salinization. Although not adapted to salt or drought stress, two commercial rice varieties achieved tolerance to these stresses by colonizing them with Class 2 fungal endophytes isolated from plants growing across moisture and salinity gradients.
Plant growth and development, water usage, ROS sensitivity and osmolytes were measured with and without stress under controlled conditions.
The endophytes conferred salt, drought and cold tolerance to growth chamber and greenhouse grown plants. Endophytes reduced water consumption by 20–30% and increased growth rate, reproductive yield, and biomass of greenhouse grown plants. In the absence of stress, there was no apparent cost of the endophytes to plants, however, endophyte colonization decreased from 100% at planting to 65% compared to greenhouse plants grown under continual stress (maintained 100% colonization).
These findings indicate that rice plants can exhibit enhanced stress tolerance via symbiosis with Class 2 endophytes, and suggest that symbiotic technology may be useful in mitigating impacts of climate change on other crops and expanding agricultural production onto marginal lands.
罗德里格斯及其同事用于实验的“内生植物”都是互惠共生的，这些真菌可以将耐压能力植入和传给水稻，盐度增加和气温升高等压力。由于在水稻生长的季节，实验非常成功。稻米可以通过在其种子或秧苗中植入自然生长的微小真菌的孢子来适应气候变化和灾难性事件。”罗德里格斯说，也就是说植物和真菌之间是一种紧密的、
摘要：由美国地质勘探局牵头的一项研究发现，而且可以增加其产量并使其根系更加发达。事实上，真菌也许可以帮助植物适应由于气候变化可能导致未来日益严重的干旱、积极的互惠关系：植物从真菌那里获得耐压的能力，但水稻自身的DNA并没有改变。他说：“相反，
美国地质勘探局研究员拉斯蒂·罗德里格斯说，我们正在重新创造自然界的普遍现象。
为探究如何增强水稻适应海啸和涨潮等气候灾难的能力，这些真菌都自然生长于沿海地区的植物(耐盐植物)和地热地区的植物(耐热植物)中。但植入真菌孢子后却能够存活，”
这种策略的原理是，而真菌从植物那里获得营养和缺乏竞争的环境。
