Stepwise evolution of the developmental and symbiotic functions of DELLA in land plants

Katharina Melkonian, Tifenn Pellen, Katinka Bünger, Oceane Thiercelin, Aurélie Le Ru, Mélanie K. Rich, Matheus E. Bianconi, Jean Keller, Maxime Bonhomme, Pierre‐Marc Delaux

The paper investigates the evolutionary conservation of DELLA protein functions in liverworts and finds GA-independent developmental roles are conserved, but DELLA is not involved in mycorrhizal symbiosis.

A single genetic innovation at the origin of plant terrestrialization

Duchesse Lacourt Mbadinga Zamar, Philippe Ranocha, Mélanie K. Rich, Katharina Melkonian, Tatiana Vernié, Tifenn Pellen, Nicolas Vigneron, Jean Keller, Frédéric Domergue, Yves Martinez, Aurélie Le Ru, Christophe Dunand, Pierre‐Marc Delaux

This study identifies a single genetic innovation, p-GPATs, as critical for the evolution of the plant cuticle and Arbuscular Mycorrhizal symbiosis during terrestrialization.

EPP1 is an ancestral component of the plant Common SymbiosisPathway

Mélanie K. Rich, Tatiana Vernié, Manish Tiwari, Lucie Chauderon, Julie Causse, Tifenn Pellen, Alice Boussaroque, Matheus E. Bianconi, Michiel Vandenbussche, Pierre Chambrier, Aurélie Le Ru, Baptiste Castel, L. V. Sairam Nagalla, Julie V. Cullimore, Jean Keller, , Pierre‐Marc Delaux

The paper identifies EPP1 as a fourth gene in the ancestral common symbiosis pathway, essential for plant-microbe interactions across multiple plant clades.
