A tissue-specific rescue strategy reveals the local roles of autophagy in leaves and seeds for resource allocation.

Abstract excerpt

Autophagy is a vesicular mechanism that plays a fundamental role in nitrogen remobilization from senescing leaves to seeds. The Arabidopsis (Arabidopsis thaliana) autophagy (atg) mutants exhibit early senescence, reduced biomass, and low seed yield. The atg seeds also exhibit major changes in N and C concentrations. During plant development, autophagy genes are expressed in the source leaves and in the sink seeds...
