Digitised herbarium specimen data reveal a climate change‐related trend to an earlier, shorter Canadian Arctic flowering season, and phylogenetic signal in Arctic flowering times

New Phytologist, EarlyView.
Summary The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Decoding plant defense signaling using the defenseless mutant

New Phytologist, EarlyView.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),

MITOGEN‐ACTIVATED PROTEIN KINASE9 fine‐tunes hypoxia signaling by phosphorylating ERF‐VII transcription factors in Arabidopsis

New Phytologist, EarlyView.
Summary In plants, hypoxia sensing is controlled by the stabilization of group VII ethylene response factors (ERF‐VIIs), which are post‐translationally activated by the mitogen‐activated protein kinases (MAPKs) MPK3 and MPK6. However, how plants fine‐tune the MPK3/MPK6‐mediated phosphorylation of ERF‐VIIs to maintain cellular homeostasis remains ...
