Myxospores

Definition

Myxospores are specialized, dormant cells formed by certain myxobacteria within fruiting bodies. They are resistant to desiccation and can survive harsh environmental conditions until favorable conditions return.

5 Must Know Facts For Your Next Test

1. Myxospores are produced by myxobacteria, a subgroup of Proteobacteria.
2. They are typically formed within complex multicellular structures called fruiting bodies.
3. Myxospores exhibit high resistance to desiccation and other environmental stresses.
4. They enable the survival of myxobacteria in unfavorable conditions by entering a dormant state.
5. Upon returning to favorable conditions, myxospores can germinate and resume active growth.
