Midwestern soils are among the most productive in the world, thanks in part to extensive tile drainage systems that remove excess water from crop fields. But water isn’t the only thing flowing through tile drains. Nitrogen moves along with soil water into drainage ditches, streams, and ultimately into the Mississippi River Basin, where the nutrient contributes to massive algal blooms and hypoxic conditions that impact aquatic life in the Gulf of Mexico.

Scientists have discovered a genetic mechanism in pak choi that boosts drought tolerance by regulating ascorbic acid levels. By silencing the BcSRC2 gene, researchers found that the plant’s ascorbic acid content decreased, reducing its drought resistance. Conversely, overexpressing BcSRC2 raised ascorbic acid levels, enhancing the plant’s tolerance. This finding could guide future breeding strategies to help crops cope with water scarcity.
