Special Issue Information

Dear Colleagues,

Endosymbiotic algae is vital to the health of its host and homeostasis of the aquatic ecosystem. Given the mutualistic association of algae with invertebrates such as corals and sea anemone, the stability of this association impacts the neutral lipids level and physiology of the endosymbiont under stress environment condition. Lipids are essential biomolecule components in endosymbiotic algae. They are stored in a large amount of spherical organelles called lipid droplets, which are found in all organisms and play important biological roles as signaling molecules and nutrient sources. Various studies have indicated that lipid droplets in endosymbiotic algae can be induced under extreme environmental conditions, including low-nutrient and low-temperature conditions. Considering that the lipid droplets produced by the endosymbiotic algae are not only necessary for themselves, but also for the host, elucidation of lipid droplet proteins, biogenesis formation, as well as cellular and molecular biology mechanisms provides an opportunity for researchers to explore the novel discovery and development of lipid droplet in endosymbiotic algae.

This Special Issue invites academics and researchers to submit reviews, original articles, and short communications focusing on lipid droplet identification, biological roles, and molecular functions in endosymbiotic algae. Studies may address lipid droplets biological studies, as well as new aspects of lipid droplets for further novel development in the field.

Symbiodiniaceae species is a dinoflagellate that plays a crucial role in maintaining the symbiotic mutualism of reef-building corals in the ocean. Reef-building corals, as hosts, provide the nutrition and habitat to endosymbiotic Symbiodiniaceae species and Symbiodiniaceae species transfer the fixed carbon to the corals for growth. Environmental stress is one of the factors impacting the physiology and metabolism of the corals-dinoflagellate association. The environmental stress triggers the metabolic changes in Symbiodiniaceae species resulting in an increase in the production of survival organelles related to storage components such as lipid droplets (LD). LDs are found as unique organelles, mainly composed of triacylglycerols surrounded by phospholipids embedded with some proteins. To date, it has been reported that investigation of lipid droplets significantly present in animals and plants led to the understanding that lipid droplets play a key role in lipid storage and transport. The major challenge of investigating endosymbiotic Symbiodiniaceae species lies in overcoming the strategies in isolating lesser lipid droplets present in its intercellular cells. Here, we review the most recent highlights of LD research in endosymbiotic Symbiodiniaceae species particularly focusing on LD biogenesis, mechanism, and major lipid droplet proteins. Moreover, to comprehend potential novel ways of energy storage in the symbiotic interaction between endosymbiotic Symbiodiniaceae species and its host, we also emphasize recent emerging environmental factors such as temperature, ocean acidification, and nutrient impacting the accumulation of lipid droplets in endosymbiotic Symbiodiniaceae species.
