The role of programmed cell death in the pore formation of pome fruit KU Leuven
Oxygen is essential for plants and detached plant organs (ie., fruits and vegetables) due to its role in energy metabolism. As plants are sessile, they have limited ways to respond to oxygen deficiencies. Bulky plant organs including apple and pear fruit maintain their internal oxygen levels via the development of an intricate pore network during fruit growth. The air channels are created as part of normal tissue development. One example of ...
