Table I. Classifications of the heat-induced genes differentially regulated by HSFA1s and HSFA2

Heat shock-induced genes in three major groups (HSFA1s preferring, no significant preference, and HSFA2 preferring) were categorized based on published information functions predicted in The Arabidopsis Information Resource (Lamesch et al., 2012).
