Temporal Variation in Tower-Based Solar-Induced Chlorophyll Fluorescence and Its Environmental Response in a Chinese Cork Oak Plantation

open access: yesRemote Sensing, 2023
With the development of spectrum observation technology, solar-induced chlorophyll fluorescence (SIF)—an effective substitute for photosynthesis—has been widely used to monitor crop stress, vegetation phenology and ecosystem productivity.

Investigation of carbon and energy metabolic mechanism of mixotrophy in Chromochloris zofingiensis

open access: yesBiotechnology for Biofuels, 2021
Background Mixotrophy can confer a higher growth rate than the sum of photoautotrophy and heterotrophy in many microalgal species. Thus, it has been applied to biodiesel production and wastewater utilization.

In planta study of photosynthesis and photorespiration using NADPH and NADH/NAD+ fluorescent protein sensors

open access: yesNature Communications, 2020
NADP(H) and NAD(H) are crucial energy molecules in plant metabolism. Here, via the use of circularly permutated fluorescent protein sensors, the authors demonstrate dynamic changes in NADPH and the NADH/NAD+ ratio during photosynthesis and ...

Delayed photosynthesis response causes carbon assimilation reduction in soybean under fluctuating light

open access: yesJournal of Integrative Agriculture
Plants encounter dynamic light environments in natural field conditions, and species differ in their physiological and biochemical mechanisms for acclimating to fluctuating light (FL).

Proteorhodopsins dominate the expression of phototrophic mechanisms in seasonal and dynamic marine picoplankton communities [PDF]

open access: yesPeerJ, 2018
The most abundant and ubiquitous microbes in the surface ocean use light as an energy source, capturing it via complex chlorophyll-based photosystems or simple retinal-based rhodopsins.

A qualitative dynamic picture of the chemical kinetics for photosynthesis

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2018
In this article the photosynthetic process is described from a qualitative dynamic point of view. After a brief and mesoscopic description of the chemical process, the related chemical reactions will be discussed by a mathematical point of view at a ...

Dynamical Modeling of Photosynthesis

open access: yes, 2021
Photosynthesis, the biochemical process responsible for our survival on earth, is still rife with unknowns more than half a century after its discovery. These unknowns include its modes of function and the role of the key processes taking place apart from its regenerative Calvin cycle.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Genotype Specific Photosynthesis x Environment Interactions Captured by Automated Fluorescence Canopy Scans Over Two Fluctuating Growing Seasons

open access: yesFrontiers in Plant Science, 2019
Photosynthesis reacts dynamic and in different time scales to changing conditions. Light and temperature acclimation balance photosynthetic processes in a complex interplay with the fluctuating environment. However, due to limitations in the measurements

The Dynamic Changes of Alternative Electron Flows upon Transition from Low to High Light in the Fern Cyrtomium fortune and the Gymnosperm Nageia nagi

open access: yesCells, 2022
In photosynthetic organisms except angiosperms, an alternative electron sink that is mediated by flavodiiron proteins (FLVs) plays the major role in preventing PSI photoinhibition while cyclic electron flow (CEF) is also essential for normal growth under
