The role of the Hsp90 system in promoting and maintaining genetic complexity

从酵母到人类的各种生物的基因组测序项目已经产生了关于基因、基因家族和整个生物学进化的大量信息。在这一研究领域带来的众多惊喜中，有两个是人类拥有的基因如此之少(比之前预测的少了五倍)，以及人类与其他生物之间惊人的相似程度。很明显，仅靠基因数量不能解释地球上存在的各种形式。新出现的观点是，这些基因是如何被调控的，在生物学中的作用比之前认为的要大得多。

Genome sequencing projects of organisms ranging from yeast to humans have yielded an enormous amount of information regarding evolution of genes, gene families and biology as a whole. Two of the many surprises that have come from this area of research are how few genes humans have (five times fewer than had been previously predicted) and the striking degree of similarity between humans and other organisms. It has become clear that gene numbers alone cannot explain the vast array of forms present on the planet. The emerging view is that how these genes are regulated plays a much larger role in biology than previously thought.
