Autophagy of whole and partial chloroplasts in individually darkened leaves: a unique system in plants?

Abstract

Chloroplasts are the characteristic organelle of photoautotrophs. To acquire carbohydrates, the majority of leaf nitrogen is distributed to chloroplasts as photosynthetic proteins. During age-related senescence or under starvation conditions, chloroplasts become a major source of carbon and nitrogen for recycling. While bulk degradation of the cytosol and… (More)
