This project aims to elucidate the molecular response of hardwood tree seedlings to heat, cold, drought, mechanical wounding, and varying levels of ozone concentration. Ozone pollution places environmental stress on forest trees resulting in early leaf senescence and loss of photosynthetic capacity.


MiSeq reads from 45 libraries were cleaned with Trimmomatic and assembled by Trinity. CD-hit with parameter -c 0.95 was used to collapse highly similar reads into a single sequence. Protein sequences were predicted using Trinity. Data has been uploaded to NCBI ( go to NCBI BioProject page).

Read Statistics

RNA was sampled from leaves of seedlings exposed to ozone levels (control, 10ppm, 80ppm, 125ppm, or 225ppm) for 7 hours, 14 days, and 28 days. Leaf, petiole, and root samples were also taken from seedlings exposed to control, cold (4 hours, 24 hours), heat (4 hours, 24 hours), drought (7 days, 21 days, 32 days), and wounding (0 hours, 3 hours, 5 hours, 24 hours). Raw data has been uploaded to the NCBI Short Read Archive. Links are included below.
