Histones are characterized by numerous posttranslational modifications that influence gene transcription.

组蛋白的特点是大量的翻译后修饰，这些修饰可以影响基因转录。

Signal transmission can be quenched by inhibition of N-acyl-homoserine-lactone, leading to breaking the initial of pathogenic genes transcription and the expression of virulence.

目前发现参与这种信息传递最普通的信号分子是N-脂酰高丝氨酸内酯。
