Genome-wide association study elucidates the genetic architecture of manganese tolerance in Brassica napus

This study identifies genetic loci and genes involved in manganese tolerance in canola using genome-wide association analysis and functional assays.

Cell-specialized chloroplast signaling orchestrates photosynthetic and extracellular reactive oxygen species for stress responses

This study identifies how chloroplast retrograde signals like PAP coordinate ROS production in guard cells to regulate stomatal closure during stress.

Reducing PSY activity fine tunes threshold levels of a cis-carotene-derived signal that regulates the PIF3/HY5 module and plastid biogenesis

The paper identifies PSY genetic variants that fine-tune cis-carotene levels, affecting the PIF3/HY5 module and plastid biogenesis in Arabidopsis.

Dynamics of mRNA fate during light stress and recovery: from transcription to stability and translation

The paper investigates how mRNA stability, transcription, and translation change during light stress and recovery in Arabidopsis thaliana, finding transcript destabilisation during stress and stabilisation during recovery.

Enzymes degraded under high light maintain proteostasis by transcriptional regulation in Arabidopsis

The paper shows that under high light stress in Arabidopsis, nuclear-encoded enzymes with increased degradation rates are compensated by transcriptional upregulation to maintain proteostasis, while plastid-encoded proteins rely on other mechanisms.

Autophagy promotes photomorphogenesis during seedling development in Arabidopsis in carbon limiting conditions

This study shows autophagy promotes photomorphogenesis in Arabidopsis seedlings under carbon limitation by enhancing lipid turnover and chloroplast development.

Retrograde Control of Cytosolic Translation Targets Synthesis of Plastid Localized Proteins and Nuclear Responses for Efficient Light Acclimation.

The paper identifies a translation-dependent retrograde signaling pathway that regulates chloroplast protein synthesis and nuclear responses to light acclimation.

Excess light priming in Arabidopsis thaliana with altered DNA methylomes

The study shows that Arabidopsis thaliana can maintain photoprotection and priming against recurring excess light despite altered DNA methylation.

A cis-carotene derived apocarotenoid regulates etioplast and chloroplast development

Carotenoids are not just required as core components for plastid biogenesis, they can be cleaved into an apocarotenoid signal that regulates etioplast and chloroplast development during extended periods of darkness.
