A little guide for advanced search:

Tip 1. You can use quotes "" to search for an exact expression.
Example: "cell division"
Tip 2. You can use + symbol to restrict results containing all words.
Example: +cell +stem
Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
Example: +cell -stem

e.g. searching for members in projects tagged cancer

Although sigma factor-dependent transcriptional regulation was shown to be essential for adaptation to different environmental stimuli, no such sigma factor has been related to the regulation of the cold shock response in Bacillus subtilis. In this study, we present genetic evidence for participation of sigma(L) (sigma(54)) and the two sigma(L)-dependent transcriptional enhancers BkdR and YplP in the cold shock response of Bacillus subtilis JH642. Single-gene deletion of either sigL, bkdR, or yplP resulted in a cold-sensitive phenotype.
