Transcriptome profiles of multifactorially stressed plants. A, Number of statistically significant features for each stress condition identified by volcano-plot analysis. The significance threshold was set at change greater than 2-fold and false discovery rate less than 0.05. B, Intersection identifying at least 2-fold statistically significant entities present in all stress conditions as well as features unique to individual treatments. Conditions are as follows: heat (h), drought (d), TuMV (v), drought and heat (dh), TuMV and heat (vh), drought and TuMV (dv), TuMV, drought, and heat (vdh), and severe heat (severe h).
