A metabolic link between #photorespiration and epigenetic regulation underlying stress memory. Therefore, climate-driven shifts in photorespiratory flux under rising CO2, heat, and drought may reprogram plant epigenomes and influence acclimation and adaptation.

Photorespiration is linked to DNA methylation by formate as a one-carbon source - Nature Plants This study reveals that Arabidopsis reassimilates formate produced during photorespiration via the cytosolic folate cycle to fuel DNA methylation, forming a metabolic–epigenetic bridge that links elev...

#Photorespiration fuels C1 metabolism to support DNA methylation in Arabidopsis, linking photosynthetic C flux to #epigenome stability & showing how rising CO₂ can reshape the plant #methylome.

Interesting questions remain: Why do some pathways improve CO2 assimilation even in CO2-rich environments?

“By engineering alternative photorespiratory pathways and identifying optimal growing conditions, our work aims to maximize impact on improving crop yields.”

Wenn Bäume kein CO2 mehr aufnehmen, sondern zu husten beginnen Wälder sind wichtige CO2-Senken, aber ausgerechnet wenn es wärmer und trockener wird, kehrt sich die Photosynthese in Photorespiration um und geben Bäume CO2 ab.

„Wissenschaftler konnten nun aber nachweisen, dass Bäume, wenn es heißer & trockener wird, nicht mehr #CO2 einatmen, sondern gewissermaßen ins Keuchen kommen & zusätzlich CO2 in die sowieso schon gesättigte Luft abgeben“ #Photorespiration
