Life of a Lab Rat: Plant Defence 3 - Acquired Resistance

Life of a Lab Rat: Plant Defence 3 - Acquired Resistance | Botany teaching & cetera | Scoop.it

"This post looks at how surviving one bacterial attack can make plants more able to survive subsequent ones with both local and systemic acquired resistance.

 

Locally acquired resistance is the simplest to manage, and provides a clear advantage. If cells have been attacked once it makes sense to defend them in case of a second attack."

How the first plant came to be | Botany teaching & cetera | Scoop.it
A genetic analysis reveals the ancient, complex — and symbiotic — roots of photosynthesis in plants.
Eve Emshwiller's insight:

DNA of a glaucophyte sheds light on the endosymbiotic origin of plastids (chloroplasts).  Too bad they describe the glaucophytes as "blue-green algae" - which is usually used to mean cyanobacteria.
