About this Research Topic
The need for chlorophyll fluorescence measurements in biological and agricultural studies is increasing enormously. This is because they provide a universal tool for a quick, cheap and reliable evaluation and analysis of plant responses to environmental perturbations and stresses that affect the efficiency of photosynthesis. Chlorophyll fluorescence measurements are usually applied to predict, discover and understand the changes in the function and structure of the photosynthetic machinery. Additionally, some non-standard applications, such as the monitoring of global earth photosynthesis in diverse ecosystems, the assessment of fruit and seeds maturity, and the implementation of online tools for evaluating quality of drinking water are also becoming increasingly common.
Remarkably, this is the only known method in biological and agricultural sciences that can be applied at both molecular and global scale, deliver large amount of data in a short time, and express the level of performance of any photosynthesizing living organism, non-invasively.
In this Research Topic we welcome Reviews and Original Research Articles that aim to expand our knowledge and understanding of chlorophyll fluorescence measurements and their applications in the biological relevant context of environmental stress responses. Submitted manuscripts can be related to any type of method or chlorophyll fluorescence signal: prompt, modulated, delayed, sun-induced or laser. The submitted research articles can also focus on a combination between chlorophyll fluorescence and photosynthesis rate measurements or other related processes and analyses.
More specifically, in this Research Topics we welcome studies focused on:
• Explaining the relationship between photosynthetic electron transport and photosynthesis process under abiotic stresses.
• Understanding the cascade reactions within the photosynthetic apparatus, and the structure-activity relationships that could help revealing the mechanisms and strategies of plant survival under stress conditions.
• Clarifying the physiological significance, as well as the calculations and applications of chlorophyll fluorescence parameters, and comparing the output of different methods and tools used to measure chlorophyll fluorescence.
• Comparing the output of chlorophyll fluorescence measurements with other techniques used to study the photosynthetic process.
• Describing the application of chlorophyll fluorescence in plant phenotyping and plant breeding programs to monitor and select for tolerance of abiotic stresses - including mineral deficiencies, drought, water excess, salinity, low and high temperature.
