Distinct transcriptional profiles of ozone stress in soybean (Glycine max) flowers and pods.

ABSTRACT:

Background

Tropospheric ozone (O3) is a secondary air pollutant and anthropogenic greenhouse gas. Concentrations of tropospheric O3 ([O3] have more than doubled since the Industrial Revolution, and are high enough to damage plant productivity. Soybean (Glycine max L. Merr.) is the world's most important legume crop and is sensitive to O3. Current ground-level [O3] are estimated to reduce global soybean yields by 6% to 16%. In order to understand transcriptional mechanisms of yield loss in soybean, we examined the transcriptome of soybean flower and pod tissues exposed to elevated [O3] using RNA-Sequencing.

Results

Elevated [O3] elicited a strong transcriptional response in flower and pod tissues, with increased expression of genes involved in signaling in both tissues. Flowe
