The study of autophagy in plants is rapidly increasing, due to its pivotal and fundamental roles in responding to stressful stimuli, recycling nutrients during senescence, and maintaining growth under normal conditions. Assays for detecting autophagy in plants have generally been based on microscopic observations, providing qualitative information on autophagy activity. Here, we discuss biochemical assays for detecting autophagy, which have the potential for providing more quantitative information, with a focus on immunoblotting with antibodies against ATG8, NBR1, or epitope tags fused to ATG proteins. |
