Yi Ketai plant light system II function comprehensive research technology program
January 24, 2022
Photosynthesis is the process by which plants, including algae and photosynthetic bacteria, absorb solar energy, convert CO 2 and water into organic matter (chemical energy), and release O 2 . Photosynthesis is the most important producer of the entire biosphere, and the continuous production of O 2 for other organisms is arguably the most important biological reaction process on the planet. Therefore, photosynthesis research has always played a pivotal role in plant and agricultural research. Photosynthesis occurs on the thylakoid membrane in the chloroplast. The thylakoid membrane is intercalated with photosystem I and photosystem II (PSI and PSII). Since the optical system II is located at the front end of the optical system I, it also contains an oxygen-evolving complex. Therefore, the most important aspect of photosynthesis research is the study of photosystem II. Recently, the optical system II function comprehensive research system that has just been commissioned and installed at Shandong Agricultural University consists of four functional units: FluorCam closed chlorophyll fluorescence imager, FL6000 dual modulation chlorophyll fluorescence meter, TL6000 plant thermoluminescence meter, PlanTherm PT 100 Plant heat tolerance measuring instrument. FluorCam closed chlorophyll fluorescence imager is used for measuring and imaging various parameters of chlorophyll fluorescence quenching kinetics, especially for studying the changes of stress response and mutant screening in different parts of plants. At the same time, the FluorCam closed chlorophyll fluorescence imager is the only instrument in the world that can perform macroscopic OJIP rapid fluorescence kinetic imaging and QA reoxidation kinetic imaging.
The FL6000 dual-modulation chlorophyll fluorescence meter uses STF (single-turn-to-light flash) as the main measurement tool for QA-reoxidation kinetics, S-state conversion, rapid chlorophyll fluorescence induction, and other measurement procedures that cannot be completed by other conventional fluorometers. The difference in the variation of the light system II. At the same time, it can also measure PAM (pulse modulation) measurement, OJIP fast fluorescence kinetic measurement, time resolution up to 1μs, the world's most recognized chlorophyll fluorescence instrument with the most comprehensive function and highest time resolution.
The TL6000 plant thermoluminescence meter detects the stability of the photosystem II S 2 Q B − , S 3 Q B − , the activity of the oxygen-releasing complex and the S-state transition by detecting the temperature-thermoluminescence intensity curve of the photosystem II. Thus, the depth of the research of Photosystem II is advanced to the level of a specific step of photosynthetic electron transfer. This is also the only commercially available optical system II thermoluminescence measuring instrument.
The PlanTherm PT 100 Plant Thermal Tolerance Meter measures the thermal stability and thermal sensitivity of plants from both cell membrane heat damage and photosystem II heat stress. This comprehensive system represents the highest peak of international luminosity II research technology and is the best choice for in-depth research on photosynthesis. In addition to Shandong Agricultural University, the Institute of Botany of the Chinese Academy of Sciences, the Institute of Aquatic Sciences of the Chinese Academy of Sciences, Shanghai Normal University, Henan University and other units are also equipped with this system.
