Key Points

The aim is to explore the dynamic interactions among organelles during the development of male gametophytes.
Electron microscopy was used to observe organelle interactions in plant male gametophytes.
Specific observations were made on the behavior of mitochondria and lipid bodies across developmental stages.
Micro-lipophagy and membrane contact sites were analyzed for their roles in organelle interactions.
Mitochondria were found to envelop nuclei at specific developmental times.
Lipid bodies surrounded sperm cells, showing dynamic changes during maturation.
Vacuoles were observed to interact with lipid bodies, undergoing a process of fusion and breakdown.
