Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

New Phytologist, Volume 251, Issue 2, Page 768-781, July 2026.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

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, Volume 251, Issue 2, Page 696-706, July 2026.
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.

An N‐acetyltransferase‐MAPK fusion protein modulates developmental reprogramming in Physcomitrium patens

New Phytologist, Volume 251, Issue 1, Page 321-339, July 2026.
Summary We discovered a previously uncharacterized moss‐specific protein, Rosetta NATD‐MAPK 1 (RAK1) in Physcomitrium patens, which uniquely integrates MAP kinase (MAPK)‐dependent signaling with N‐acetyltransferase activity. Through phenotypical and biochemical analyses, we characterized RAK1 function in the regulation of the 2D‐to‐3D growth transition.

VERNALIZATION2 alters early tiller development in a facultative spring hexaploid bread wheat

New Phytologist, Volume 250, Issue 6, Page 4022-4035, June 2026.
Summary An extended period of cold exposure enables the process of vernalization in winter cereals and is important for the synchronised timing of the floral transition. The cereal‐specific floral repressor VERNALIZATION2 (VRN2) has an integral role in vernalization, yet this locus remains poorly characterised in facultative spring hexaploid wheat ...

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, Volume 250, Issue 6, Page 3732-3746, June 2026.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...
