The composition of the thylakoid proton motive force (pmf) is regulated by ion transport. Passive channels in membrane dissipate potential (Ɗψ) component to allow for a higher fraction pmf stored as concentration gradient (ƊpH). K+/H+ antiport across via K+ EXCHANGE ANTIPORTER3 (KEA3) instead reduces ƊpH pmf. Thereby, KEA3 decreases nonphotochemical quenching (NPQ), thus allowing light use efficiency, which particularly important during transitions from high low light. Here, we show that...
Photosynthesis is limited by the slow relaxation of nonphotochemical quenching, which primarily dissipates excess absorbed light energy as heat. Because heat dissipation process proportional to light-driven thylakoid lumen acidification, manipulating ion and proton flux via transport proteins could improve photosynthesis. However, an important aspect current understanding transportome inaccurate. Using fluorescent protein fusions, we show that Arabidopsis (
Repeated shifts in ecological strategies often lead to consistent speciation patterns across phylogenies. One example is the transition from outcrossing self-fertilization plants, which generally results reproductive isolation of incipient selfing lineages. However, evolutionary mechanisms driving their remain poorly understood. In this study, we investigate hybridization rate and barriers gene flow between recently evolved lineage Capsella rubella its ancestor C. grandiflora. Through a...
Organisms can rapidly mitigate the effects of environmental changes by changing their phenotypes, known as phenotypic plasticity. Yet, little is about temperature-mediated plasticity traits that are directly linked to plant fitness such flower size. We discovered substantial genetic variation in size temperature both among selfing Arabidopsis thaliana and outcrossing A. arenosa individuals collected from a natural growth habitat. Genetic analysis using panel 290 accession mutant lines...
Phenotypic plasticity is a heritable trait that provides sessile organisms strategy to rapidly mitigate negative effects of environmental change. Yet, we have little understanding the mode inheritance and genetic architecture in different focal traits relevant agricultural applications. This study builds on our recent discovery genes controlling temperature-mediated flower size Arabidopsis thaliana focuses dissecting combining ability context plant breeding. We created full diallel cross...
