Does The Production Of Isoprene Affect The Productivity Of Poplars?, Erik J. Mcfarland, Elizabeth Ann Parra, Greg Barron-Gafford, Rebecca Larkin Minor, Maggie Heard

STAR Program Research Presentations

Poplar trees are known to produce a chemical called isoprene that plays a complex, and not fully understood, role in the chemical process of photosynthesis. Understanding why plants produce isoprene and under what conditions will help scientists make more accurate predictions about poplars’ photosynthetic capabilities in future climates.

What benefit could isoprene provide a plant? The literature suggests its production could help plants tolerate heat stress. We studied two genetic lines of trees in a common garden of Populus, one line with the gene for producing isoprene and a second line without that gene. We subjected some trees of …
