From: Fusarium head blight resistance exacerbates nutritional loss of wheat grain at elevated CO2
Percent grain starch accumulation of various Fusarium head blight (FHB) moderately resistant (MR) and susceptible wheat cultivars. Starch accumulation determined by evaluating differences in starch content from wheat grown at elevated CO2. (a) Grain starch content of susceptible and MR wheat grain grown at ambient (a[CO2]) and elevated (e[CO2]), error bars represent standard error. (b) Percent starch accumulation at e[CO2] by cultivar and FHB resistance score. Horizonal bars represent group mean starch accumulation, error bars represent standard error. Wheat cultivars were ordered by FHB resistance score at the top of the figure panel. (c) Percent starch accumulation by FHB group. Different letters or asterisks (*) denote statistically significant differences as determined by a Tukey adjusted generalized mixed model analysis of variance (P < 0.05); MR (n = 27), and susceptible (n = 18), for each CO2 growth condition.
