Controlling a gene's activity is fundamental in biotechnology, from dissecting a gene's function to introducing desired traits in crop plants. Recently a new class of genes have been identified that are 'master-regulators' able to control the activity of many genes, and through this, they can ultimately control how an organism develops and functions. By understanding how these genes operate and the extent of their influence, not only will we gain greater insights into the gene regulatory networks required for multicellular life, but how we may develop methods of controlling gene activity that will have tremendous biotechnological applications.

控制基因的活性是生物技术的基础，从剖析基因的功能到将所需的性状引入作物。最近，一类新的基因被鉴定为能够控制许多基因活性的“主调节因子”，通过这种方式，它们最终可以控制生物体的发育和功能。通过了解这些基因如何运作及其影响的程度，我们不仅可以更深入地了解多细胞生命所需的基因调控网络，而且可以开发出控制基因活性的方法，这些方法将具有巨大的生物技术应用。
