Excessive salt is a major factor limiting crop productivity. Rice is an important food crop worldwide, and provides a major source of calories for billions of people in tropical and subtropical developing countries. In many regions throughout Southeast Asia, rice is grown in low-lying coastal regions, which are prone to ingress by seawater. Rice is highly sensitive to salt stress, with mild salinity resulting in large reductions in yield. Improving salt tolerance in rice is essential for ensuring food security for many individuals throughput the developing world.
In this work, the overall goals were to characterize a diverse collection of …

Drought is the most significant abiotic stress affecting agricultural production. Improving seed yield under water stress is an important breeding objective. Soybean cultivars that tolerate water stress could help improve and stabilize production in water-stressed environments. “Drought” needs to be defined, because water stress can vary in intensity, timing, and duration. Other factors including ambient temperature, soil texture, depth, and fertility will influence the impact of limited water on crop productivity. This research addresses the impact of water stress on soybeans adapted to the north-central US, where the majority of soils are relatively deep, fertile silt loams or silty clay …
