something about Azotobacter vinelandii

Post by wwclq » Mon Jan 03, 2011 1:56 pm

It is said that when Azotobacter vinelandii faces a difficult situation ,it can have some thing like a spore ,which called "cyst". So,what are the differences between them? And how can they make such changes?

I guess you mean spores. These are highly resistant to either dryness, irradiance, lack of nutrients etc., but they do not grow nor divide, so they cannot compete with other, active cells ;)

Cis or trans? That's what matters.

if you're dead-like, you don't need water ;) And if you have enough mechanisms to repair your DNA, you can be quite fine even after dryness :)
