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.

How natural selection acted on one penguin species over the past quarter century
University of Washington biologist Dee Boersma and her colleagues combed through 28 years’ worth of data on Magellanic penguins to search for signs that natural selection — one of the main drivers of evolution — may be acting on certain penguin traits. As they report in a paper published Sept. 21 in The Auk: Ornithological Advances, selection is indeed at work on the penguins at the Punta Tombo breeding site in Argentina.

UW conservationists celebrate new protected areas for Argentine penguins
On Dec. 3, the legislature for Argentina’s Chubut province established a new marine protected area off Punta Tombo, which would help preserve the feeding grounds for about 500,000 Magellanic penguins that make their home along this rocky stretch of Argentine coast. This is welcome news for the UW scientists who have studied these penguins for decades and advocated for their conservation.

Trees either hunker down or press on in a drying and warming western U.S. climate
Two University of Washington researchers have uncovered details of the radically divergent strategies that two common tree species employ to cope with drought in southwestern Colorado. As they report in a new paper in the journal Global Change Biology, one tree species shuts down production and conserves water, while the other alters its physiology to continue growing and using water.
