Autophagy is a cellular process involved in recycling and degradation of cellular components to maintain cellular homeostasis. It is known to play a crucial role in regulating senescence by removing damaged or unwanted cellular components. Therefore, plants defective in autophagy would typically show impaired or delayed senescence rather than accelerated senescence.

The correct statement is that plants defective in autophagy demonstrate impaired or delayed plant senescence. Hence, the correct answer is option 3.
