Tracing the evolutionary origins of plant hormones
Research with ÚEB, Charles University, and Ghent University found that plant hormones already occur in freshwater green algae, though they likely gained their growth-regulating functions only after plants moved onto land. Read the ÚEB feature →

Honorary doctorate for Prof. Zažímalová
Marking its 70th anniversary, the University of Chemistry and Technology Prague awarded an honorary doctorate to Eva Zažímalová — who led LHR for many years before becoming ÚEB director and chair of the Czech Academy of Sciences — recognising her work on the hormone auxin (in Czech).

Linking auxin transport to cell membranes
An international team led on the Czech side by LHR head Jan Petrášek traced a chain of steps linking changes in the cell membrane to regulation of auxin flow, published in Nature Plants (in Czech). Read the ÚEB feature →

Prof. Zažímalová named Top Woman of the Czech Republic
Eva Zažímalová — who led LHR for many years before becoming ÚEB director and, since 2017, chair of the Czech Academy of Sciences — won the Public Administration category of the Top Women of the Czech Republic awards for her work on plant hormones (in Czech). Read the ÚEB feature →

How cells keep auxin levels in balance
LHR head Jan Petrášek’s team — with lab colleagues Klára Hoyerová, Petr Hošek, and Michaela Helusová among the co-authors — showed how plant cells regulate their internal auxin concentration by controlling the activity of transport-protein genes, published in The Plant Journal (in Czech).

How roots respond to gravity
Czech and Austrian researchers, with LHR head Jan Petrášek among the co-authors, described how brassinosteroid hormones regulate the auxin-transport protein PIN2 in root cells, revealing dynamics quite different from what was previously assumed, published in Nature Communications (in Czech).
