多个染色体位置中多组基因的受调节激活是真核生物和原核生物细胞分化的标志。经历复杂发育周期的某些细菌物种作为研究此类基因调控机制的系统特别有吸引力,因为它们非常适合生化和遗传方法。枯草芽孢杆菌就是这样一种系统,它在形成孢子时会经历广泛的细胞分化。现在,在这种革兰氏阳性物种中,有许多新方法可用于识别、操作和研究参与孢子形成的基因的调节,包括使用转座遗传元件,作为插入基因的自动结果,在体内产生基因融合。
The regulated activation of numerous sets of genes in multiple chromosomal locations is a hallmark of cellular differentiation in both eukaryotes and prokaryotes. Certain species of bacteria that experience complex developmental cycles are especially attractive as systems in which to study the mechanisms of this kind of gene regulation because they are highly amenable to both biochemical and genetic approaches. Bacillus subtilis, which undergoes extensive cellular differentiation when it sporulates, is one such system. Many new methods are now available in this Gram-positive species for identifying, manipulating, and studying the regulation of genes involved in spore formation, including the use of transposable genetic elements that create gene fusions in vivo as an automatic consequence of insertions into genes.
