皮赫兹 (pHz) 单位定义. The picohertz is a multiple of the unit hertz (Hz) for frequency. The International System of Units (SI) defines the prefix pico (p) as a factor of 10⁻¹² or …

However, only 58 transcriptional units containing 99 genes contained phz-boxes within the 500-bp promoter region, suggesting indirect regulation of the majority of genes (Table 3). Consistent...

Autoactivation of phzR in strain 2-79 requires an intact phz box (Table 3), suggesting that PhzR must bind to this site to activate expression of its own gene. However, the phz box is located …
