Plants and Algae in the Frequency Domain
Summer School and Workshop
Český Krumlov, Czech Republic
Aug.25-29, 2025
DREAM
The Summer School and, in part, the Workshop will be funded by HORIZON-EIC-2021PATHFINDER OPEN project DREAM, grant agreement no. 101046451
“Bringing precision agriculture to the next generation:
Dynamic regulation of photosynthesis in light-acclimated organisms”
Invitation
Alternating electric currents and alternating electromagnetic fields revolutionized physics and engineering and led to many technologies that shape modern life. Despite these undisputable achievements, which have been reached using stimulation by harmonic oscillations over centuries, applications in biology remain rare.
Photosynthesis research is uniquely suited to unleash this potential because light can be periodically modulated like currents or fields in physics. Implementing, exploiting, and understanding the response of photosynthetic organisms to periodically modulated light is hindered by the complexity of dynamics that such light elicits and by the mathematical apparatus required for understanding the signals in the frequency domain, which, although well-established and straightforward, is outside typical curricula in biology.
The Workshop will consist of sessions dedicated to:

Introduction to photosynthesis sensing in the frequency domain.

Is the information obtained in the frequency domain equivalent or complementary to the time domain methods?

Opportunities for instruments tailored to the frequency domain compared to instruments originally developed only for time-domain measurements.

Can the light-use efficiency of plants and algae in harmonically modulated light exceed that in constant light of the same average photon flux density?

Can measurements in the frequency domain yield a higher discriminative power than the time domain in sensing plant stress?

Dynamics and mechanisms of non-photochemical quenching in oscillating and fluctuating light.

The Summer School will offer junior researchers an introduction to the theoretical and methodological fundamentals required to understand plants’ and algae’s dynamic responses to oscillating and fluctuating light. The introductory session will be elemental and accessible to students of diverse backgrounds, but a willingness to explore the wonderful mathematical tools supporting the approach will be assumed. The Summer School will be organized into five lectures, each of two hours. The summer school sessions will be held in the early afternoons, allowing students to participate in the workshop sessions in the mornings and late afternoons. The first lecture will introduce the principles of the frequency-domain approach. The subsequent three lectures will be on using already available DREAM-developed, commercial, and DIY instruments. Some instruments will be available on-site for inspection and discussions between the students and developers. The last session will be dedicated to data analysis and databases for storing and exploiting the results obtained in the frequency domain.

International Conference on Photosynthesis Research: ICPR2026
2025-07-26 - 2025-07-30 | Liverpool, England, Liverpool, United Kingdom
The Association of Applied Biologists is delighted to bring ICPR2026 to Liverpool in the UK.
The study of photosynthesis has attracted the attention of successive legions of biologists, biochemists, chemists and physicists for over 200 years. Never in the history of photosynthesis research, however, has progress in our understanding of photosynthetic mechanisms, regulation and improvement been made as rapidly as it has over the past 5 years. Nature makes photosynthesis look easy, but the construction of artificial photosynthetic systems remains challenging. Substantial efforts to improve the efficiency and productivity of photosynthesis have the potential to increase crop yields without further increasing fertilizer and water use.
Moreover, tailoring photosynthesis to meet the needs of nature-based solutions to climate change and to the sustainability of food production remain global challenges that have to be addressed by the photosynthesis community. This meeting will galvanise participants from academia and industry to translate this new mechanistic understanding of photosynthetic function into improved crop production and more efficient terrestrial carbon sinks.

34th Western Photosynthesis Conference
2025-01-02 - 2025-01-05 | Friday Harbor Laboratories, 620 University Rd, Friday Harbor, WA, 98250, United States
The Western Photosynthesis Conference (WPC) is one of three regional photosynthesis meetings that occur annually in the United States. A primary thrust of the WPC is to bring together researchers from a wide range of disciplines including chemistry, biochemistry, biology, and biophysics to share their cutting-edge research results in the study of photosynthetic processes. Importantly, the regional meetings are focused on the inclusion, participation and development of early career scholars. Smaller regional meetings such as the WPC fulfill an important need in terms of fostering opportunities for high-level discourse by the field’s younger scientists. The WPC is focused on both fundamental and applied research that is directly related to the biological transformation of solar photons to high-energy chemical bonds. In addition to strictly biological processes, a portion of the WPC is focused on research into bio-inspired “artificial photosynthesis”. Mechanisms of light harvesting, charge separation, CO2 fixation and electron transfer are longstanding foci of the WPC. This year, the WPC aims to highlight eight research areas:

Light Stress Management
Structure-function relations in photosynthesis
Cellular and Molecular Biology of Photosynthesis
Electron transfer between photosynthetic complexes
Applied Photosynthesis
Photosynthesis at the Global/Ecosystem Scale
Evolution and Diversity of Photosynthesis
Carbon metabolism and Photorespiration

The Gordon Research Conference and Seminar on Mitochondria and Chloroplasts “Energy-Transducing Organelles: Fundamental Processes and Translation in Agriculture and Medicine” will be held at the Rey Don Jaime Grand Hotel, Avinguda de l’Hotel, Castelldefels, B, Spain.
The 2024 Gordon Research Conference and Seminar on Mitochondria and Chloroplasts will bring together established scientists and young researchers to present and discuss emerging aspects of organelle biology. Mitochondria and chloroplasts differ from other cellular compartments by their endosymbiotic origin, their semiautonomous genetic systems, their role in energy transduction, and their complex biology. The conference will have a strong focus on basic biological processes and an interdisciplinary nature that brings together scientists from the fungal, animal and plant communities. Specific sessions will be dedicated to organelle evolution, their gene expression systems, the import of proteins, their sorting and assembly into functioning complexes, organelle metabolism and their roles in respiration and photosynthesis, organelle quality control, their role in signaling and stress response, and how all these are being translated to agriculture and medicine.
