Insights into three whole-genome duplications gleaned from the Paramecium caudatum genome sequence.

abstract：:The heat-shock response is a programmed change in gene expression carried out by cells in response to environmental stress, such as heat. This response is universal and is characterized by the synthesis of a small group of conserved protein chaperones. In Drosophila melanogaster the Hsp70 chaperone dominates the profi...
