Summary
We developed a new 3D imaging technique combining tissue clearing and light sheet fluorescence microscopy to study coral endosymbionts. This method reveals detailed coral holobiont structure and physiological states, aiding reef conservation efforts.
Area of Science:
- Marine Biology
- Microscopy Techniques
- Coral Reef Ecology
Background:
- Understanding coral bleaching requires visualizing endosymbiont distribution.
- Current methods lack the resolution for in situ 3D analysis of coral holobionts.
Purpose of the Study:
- To develop a novel method for 3D imaging of coral endosymbionts.
- To enable single-cell resolution analysis of coral holobiont structure and dynamics.
Main Methods:
- Tissue clearing (TC) combined with light sheet fluorescence microscopy (LSFM).
- Application of fluorescent probes for physiological assays.
Main Results:
- Achieved high-resolution 3D imaging of coral holobionts.
- Quantified endosymbiont abundance and distribution within corals.
- Mapped physiological states like apoptosis and hypoxia in situ.
Conclusions:
- TC-LSFM is a powerful tool for studying coral symbiosis and health.
- Provides critical data for understanding coral bleaching and reef degradation.
- Supports coral reef conservation and restoration strategies in a changing climate.

01:14Photoluminescence: Applications
958
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

01:23Photoluminescence: Fluorescence and Phosphorescence
3.4K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

656
Oxygenic photosynthesis is a fundamental process in which light energy is harnessed to drive the oxidation of water, leading to the production of molecular oxygen (O₂), adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH). This process is essential for sustaining aerobic life on Earth and is primarily carried out by cyanobacteria, algae, and plants. The core of oxygenic photosynthesis lies in the thylakoid membranes, where chlorophyll pigments facilitate...

3.1K
Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
