Structural basis for far-red light harvesting in a euglenophyte photosystem II supercomplex

Rameez Arshad, Hadrien Forêt, David Kopečný, Masami Nakazawa, Farzad Hamdi, Héctor Miranda‐Astudillo, Panagiotis L. Kastritis, Pierre Cardol, Roman Kouřil

The paper presents a cryo-EM structure of a euglenophyte PSII supercomplex and identifies LhcE9 as a far-red light-harvesting antenna subunit with unique structural and functional properties.

Insight into GABA shunt-associated aldehyde dehydrogenases (ALDH) and stress responses of ALDH superfamily in moss and barley

David Jaroslav Kopečný, Jakub Bělíček, Martina Kopečná, Armelle Vigouroux, Radka Končitíková, Klaus von Schwartzenberg, Klára Supíková, Sanja Ćavar Zeljkovıć, Miroslav Valárik, Karel Müller, Roman Kouřil, Véronique Bergougnoux, S. Moréra, David Kopečný

The paper examines ALDH superfamily expression in moss and barley under stress, identifies differences in enzyme function and structure, and links gene knockouts to altered metabolite levels and stress responses.

The monomer/dimer switch modulates the activity of plant adenosine kinase

David Jaroslav Kopečný, Armelle Vigouroux, Jakub Bělíček, Martina Kopečná, Radka Končitíková, Jaroslava Friedecká, Václav Mik, Klára Supíková, Jan F. Humplík, Marine Le Berre, Stephan Plancqueel, Miroslav Strnad, Klaus von Schwartzenberg, Ondřej Novák, S. Moréra, David Kopečný

The paper investigates how the monomer/dimer switch in plant adenosine kinase (ADK) modulates enzyme activity and establishes a negative feedback mechanism to regulate adenosine and AMP levels.

Phenylacetic acid metabolism in land plants: novel pathways and metabolites

Pavel Hladík, Federica Brunoni, Asta Žukauskaitė, Marek Zatloukal, Jakub Bělíček, David Kopečný, Pierre Briozzo, Nathan Ferchaud, Ondřej Novák, Aleš Pěnčík

This study identifies four novel PAA metabolites in land plants and shows PAA and IAA share metabolic pathways, suggesting complex auxin regulation.
