Mutation of a conserved stromal C-terminus threonine residue of Photosystem II subunit S slows down NPQ induction and speeds up relaxation.

This study shows that mutating threonine-259 in PsbS affects NPQ induction and relaxation rates in Arabidopsis thaliana.

From Field Photosynthesis to Genetic Architecture: Insights from the First Dedicated Photosynthesis Hackathon

The paper reports findings from a photosynthesis hackathon that identified key insights into genetic architecture using field photosynthesis data across four crop species.

The controlled spectrum of plant form and function

The paper shows that the acquisitive-conservative axis of plant traits operates at the whole plant level, not just within individual organs, after controlling for third-variable effects.

Kinetic parameter prediction using neural networks identifies limitations to C4 photosynthesis

C4TUNE predicts photosynthesis kinetic parameters from response curves, enabling efficient simulation and identification of limiting factors in maize genotypes.

High throughput screen of NPQ in sorghum shows highly polygenic architecture of photoprotection

This study identifies the polygenic architecture of photoprotection in sorghum through a high-throughput screen of natural genetic variation in non-photochemical quenching traits.

KineticGP: a computational framework for genomic prediction of leaf photosynthesis traits

KineticGP improves prediction of leaf photosynthesis traits in maize by integrating genomic data with kinetic models of C4 photosynthesis.

Extensive photophysiological variation in wild barley is linked to environmental origin

The paper identifies photophysiological variation in wild barley linked to environmental origin through common garden experiments and GWAS.

Metabolite profiling reveals slow and uncoordinated adjustment of C4 photosynthesis to sudden changes in irradiance

This study profiles metabolites in maize under sudden irradiance changes, revealing slow metabolic adjustments and inefficiencies in photosynthesis.

Generalizability of machine learning models for plant traits using hyperspectral reflectance data: The case of maize

This study evaluates ML models for predicting maize traits using hyperspectral data across three seasons, revealing trait-specific generalizability limits and offering a robust framework for breeding applications.

Sub-optimal temperature leads to tighter coupling between photosynthetic electron transport and CO2 assimilation under fluctuating light in maize.

The paper analyzes maize CO2 assimilation under fluctuating light and finds decoupling from electron transport at room temperature, but tighter coupling under suboptimal temperature due to feedback regulation.

Faster relaxation of nonphotochemical quenching (NPQ) in C4 than in C3 species

This study shows that NPQ relaxation is faster in C4 species than in C3 species, driven by enhanced energy-dependent quenching and altered lumen pH regulation.

Chloroplast-derived hydrogen peroxide coordinates photosynthesis with stomatal opening

This study identifies chloroplast-derived hydrogen peroxide as a signal coordinating stomatal opening with photosynthesis, showing its role in balancing carbon gain and water loss in plants.

In vivo analysis of the relationship between CP26 and qE-type NPQ via higher-order Arabidopsis cp26 mutants

This study investigates the role of CP26 in NPQ regulation in Arabidopsis by analyzing higher-order cp26 mutants and shows that NPQ deficiency in these mutants is independent of qE and qZ.
