In another study based on profiles of Arabidopsis heat shock proteins (Hsp) and transcription factors (Hsf), Hsf and Hsp expression was strongly induced by heat, cold, salt, and osmotic stress, while other types of stress including drought, genotoxic stress, ultraviolet light, oxidative stress, wounding, and pathogen infection induced family or tissue-specific response patterns (Swindell et al., 2007). Here, HSP90B2P is linked to infection.
