* [http://www.ncbi.nlm.nih.gov/pubmed/22209493 Segev ''et al''.] from the lab of [[Sigal Ben-Yehuda]] demonstrate that ribosomal RNAs are degraded in aging spores by [[rny|RNase Y]]. Moreover, the authors show that individual mRNAs experience degradation or accumulation in spores. The study suggests that the kinetics of spore [[germination]] depends on the conditions  that a spore had experienced before.

* [http://www.ncbi.nlm.nih.gov/pubmed/22303282 Levine ''et al''.] from the lab of [[Michael Elowitz]] show how ''B. subtilis'' cells can defer [[sporulation proteins|sporulation]] for multiple cell cycles in response to sudden environmental stress. This deferral is controlled by a pulsed positive feedback loop in which [[phosphorelay]] kinase expression is activated by pulses of [[Spo0A]] phosphorylation.

New procedure for account creation:

  • Due to massive spam attacks, we had to change our policy for the creation of accounts. If you want to create an account, just send me a mail. We will create the account for you as quickly as possible, then you can change your password. This does not affect existing accounts, which remain active.
  • Please remember that all members of the Bacillus community are invited to create accounts and to contribute to SubtiWiki!
