Researchers modify yeast to show how plants respond to a key hormone

Researchers at the University of Washington have developed a novel toolkit based on modified yeast cells to tease out how plant genes and proteins respond to auxin, the most ubiquitous plant hormone. Their system, described in a paper published Sept. 19 in the Proceedings of the National Academy of Sciences, allowed them to decode auxin’s basic effects on the diverse family of genes that plants utilize to detect and interpret auxin-driven messages.

Plants’ future water use affects long-term drought estimates

Many popular long-term drought estimates ignore the fact that plants will be less thirsty as carbon dioxide goes up. Plants’ lower water use could roughly halve some current estimates for the extent of future drought, especially in central Africa and temperate Asia.

Floods didn’t provide nitrogen ‘fix’ for earliest crops in frigid north

Trees, sediments in floodplain

Floods didn’t make floodplains fertile during the dawn of human agriculture in the Earth’s far north. Turns out early human inhabitants can mainly thank cyanobacteria. It raises the question of whether modern farmers might reduce fertilizer use by taking advantage of cyanobacteria that occur, not just in the floodplains studied, but in soils around the world.
