Heat shock protein 27 (HSP27/HSPB1), one of the small heat shock proteins, is constitutively expressed in various tissues. Juneidi S, Gao Z, Yin H, Makunga NP, Chen W, Hu S, Li X, Hu X. Food Sci Biotechnol. Wheat plants were sampled and RNA extracted 2 weeks after heat shock treatment. Heat shock proteins (HSPs) are abundant cellular proteins involved with protein homeostasis. Hsf genes are represented by a large multigene family in plants and investigation of the Hsf gene family will serve to elucidate the mechanisms by which plants respond to stress. The transformation efficiency between cells experienced heat shock and those were not influenced by heat shock was almost the same. Hsfs can not only help organisms resist high temperature, but also participate in the regulation of plant growth and development (such as involved in the regulation of seed maturity and affects the root length of plants). This traditional protocol can be used successfully to transform most commercially available competent bacteria. Back to Transformation of competent E.coli cells with plasmid DNA page.
