Polymorphisms in the bovine HSP90AB1 gene are associated with heat tolerance in Thai indigenous cattle
Heat shock proteins act as molecular chaperones that have preferentially been transcribed in response to severe perturbations of the cellular homeostasis such as heat stress. Here the traits respiration rate (RR), rectal temperature (RT), pack cell volume (PCV) and the individual heat tolerance coef...
