Phospholipid dynamics in Aspergillus species: relations between biological membrane composition and cellular morphology.

Biological membranes, primarily composed of phospholipid bilayers, are essential structures that compartmentalize the cell from the extracellular environment. The biosynthesis and regulation of membrane lipids have been extensively studied in model organisms such as Saccharomyces cerevisiae and mammalian cells. However, our understanding of biological membrane regulation in filamentous fungi, some of which are significant in medicine, pharmacy, and agriculture, remains limited. This minireview provides a comprehensive overview of the latest knowledge, focusing on filamentous fungi of Aspergillus species. Recent progress in understanding dynamic changes in membrane lipid profiles, driven by improvements in analytical techniques for lipidomics, is also presented. Furthermore, known that the cell morphology of filamentous fungi is closely linked to its harmful and beneficial characteristics, the influence of membrane composition on cell morphology is discussed. The integration of these findings will further enhance our understanding of the biological functions of membranes in filamentous fungi.
