Analysis of plant autophagy

Abstract

Autophagy is an intercellular degradation/recycling system by which cytoplasmic components are sequestered in autophagic vesicles (autophagosomes) and delivered to the vacuole for breakdown. During the last decade, plant studies have revealed that autophagy is employed as a major route to recycle nutrients needed for plant growth and development, and to combat with a wide range of biotic and abiotic stresses. Another important outcome of these studies was the development and optimization of methods and techniques for monitoring autophagy activity in plants. In this chapter, methods frequently used in plant autophagy study, from physiological to biochemical and microscopical analyses, are discussed.
