Raising the day/night air temperatures from 30/sup 0/C/20/sup 0/C to 50/sup 0/C/40/sup 0/C increases the high temperature tolerated by Agave deserti, Carnegiea gigantea, and Ferocactus acanthodes by 6/sup 0/C to 8/sup 0/C; the increase is about half completed in 3 days and fully completed in 10 days. A 25 to 27 kilodalton protein concomitantly accumulates for all three desert succulents upon transfer to 50/sup 0/C/40/sup 0/C, while accumulation of other heat heat-shock proteins is species specific. Some of the induced proteins are more abundant at 3 days, while others (including the 25-27 kilodalton protein) remain after completion of high temperature acclimation.
