Quantifying the effect of factors controlling CO assimilation is crucial for understanding plant functions and developing strategies to improve productivity. Methods exist in numerous variants and produce various indicators, such as limitations, contributions, and sensitivity, often causing confusion. Simplifications and common mistakes lead to overrating the importance of diffusion-whether across stomata or the mesophyll. This work develops a consistent set of definitions that integrates all previous methods, offering a generalised framework for quantifying restrictions. Ten worked examples are provided in a free downloadable spreadsheet, demonstrating the simplicity and applicability to a wide range of questions.

The phycobilisome (PBS) captures light energy and transfers it to photosystem I (PSI) and photosystem II (PSII). Which and how many copies of protein subunits in PBSs, PSI, and PSII remain unbound in thylakoids are unknown. Here, quantitative mass spectrometry (QMS) was used to quantify substantial pools of free extrinsic subunits of PSII and PSI.

Plant-plant interactions are often overlooked when assessing carbon (C) cycling in plant community. Limited research exists on how nutrient competition influences soil organic carbon (SOC) dynamics via modifying rhizosphere C turnover. To address this issue, quantitative model of plant-plant interactions was established in three intercropping systems across 4 years.

Introduction: Plant growth and metabolism can be optimized by manipulating light intensity and wavelength. Since the use of light-emitting diodes (LEDs) allows easy regulation of the light spectrum, LEDs technology is largely tested to produce high-quality food. Red leaf chicory is a horticultural plant of high commercial value, rich in vitamins, minerals and phytochemical compounds with bioprotective and antioxidant roles.

Potassium (K) is a prevalent limiting factor in terrestrial ecosystems, with approximately one-eighth of the world's soils undergoing K deficiency stress. Upon encountering K deficiency stress, leaf area (LA) declines before the net photosynthetic rate (A). The sequential alterations fundamentally represent the adaptive trade-off between survival and growth in plants subjected to K deficiency stress.
