Conservation of symbiotic signalling across 450 million years of plant evolution

This study shows that the common symbiotic pathway genes are essential for arbuscular mycorrhizal symbiosis in bryophytes, indicating conservation of this pathway for 450 million years.

Cytokinins specify pluripotent stem cell identity in the moss Physcomitrium patens

The paper shows cytokinins are confined to pluripotent stem cells in moss, excluding the differentiation factor TAW1 to establish the shoot apical meristem from a single stem cell.

The transcriptional changes underlying the flowering phenology shift in response to climate warming

This study identifies transcriptional changes in Arabidopsis halleri that underlie flowering phenology shifts due to climate warming, showing reduced expression of key genes and increased FLOWERING LOCUS C activity.

KARRIKIN INSENSITIVE2 (KAI2)-dependent signaling pathway controls vegetative reproduction in Marchantia polymorpha

This study identifies the MpKAI2-dependent signaling pathway as a regulator of gemma formation and cup development in Marchantia polymorpha, with its activity modulated by environmental factors like potassium.

Contrasting and conserved roles of NPR pathways in diverged land plant lineages

This study compares NPR pathway functions across diverged land plants, finding conserved and divergent roles in stress responses and transcriptional regulation.

An ancestral function of strigolactones as symbiotic rhizosphere signals

This study identifies BSB, an ancestral strigolactone in bryophytes, which functions as a rhizosphere signal for AM symbiosis and was later co-opted as a plant hormone.

Major components in the KARRIKIN INSENSITIVE2-ligand signaling pathway are conserved in the liverwort, Marchantia polymorpha

This study identifies conserved components of the KAI2-ligand signaling pathway in the liverwort Marchantia polymorpha and shows their functional roles in KL signaling.

Lateral organ diversification in plants mediated by the ALOG protein family of transcription factors

The paper identifies MpTAW1, an ALOG family protein in Marchantia polymorpha, as a regulator of lateral organ development and meristem maintenance, showing its conserved function in specifying lateral organ identity across plant lineages.
