Abstract

Abstract: Populus spp. are dedicated woody biomass feedstocks for advanced biofuels and bioproducts. Proper growth and fitness of poplar as a sustainable feedstock depends on timely perception and response to environmental signals (e.g., light, temperature, water). Poplar leaves, like other C3 photosynthesis plants, have evolved oscillating or circadian rhythms that play important roles in synchronizing biological processes with external cues. To characterize this phenomenon at a molecular level, we employed bottom‐up proteomics using high‐resolution mass spectrometry and de novo‐assisted database searching to identify abundance changes in proteins and post‐translational modifications in poplar leaf tissue sampled across a 12/12‐hour light/dark diurnal period.
