Reproducibly oriented cell divisions pattern the first flat body structures to set up dorsoventrality and de novo meristem formation in Marchantia polymorpha

The paper describes how oriented cell divisions in Marchantia polymorpha spores establish dorsoventrality and initiate a de novo meristem, with MpC3HDZ marking the first flat prothallus structure.

The Immobilization of Hyaluronic Acid in 3D Hydrogel Scaffolds Modulates Macrophage Polarization

This paper shows that varying hyaluronic acid molecular weight in collagen-HA hydrogels can direct macrophage polarization, but chemical crosslinking of HA prevents this effect.

Microtubules and actin filaments direct nuclear movement during the polarisation of Marchantia spore cells

The paper shows that microtubules and actin filaments guide nuclear movement in Marchantia spores to establish cell polarity before division.

Long days induce adaptive secondary dormancy in seed of the Mediterranean plant Aethionema arabicum

This study shows that long-day light regimes induce secondary dormancy in Aethionema arabicum seeds, delaying germination to avoid risky summer conditions.

KATANIN-mediated microtubule severing is required for MTOC formation and function in Marchantia polymorpha

This study shows that KATANIN-mediated microtubule severing is essential for forming and functioning MTOCs in the liverwort Marchantia polymorpha.

Control of cell fate specification and patterning by an ancestral microRNA

The paper shows that MpDCL1a is essential for miRNA biogenesis and regulates auxin synthesis, influencing cell identity and body development in the last common ancestor of land plants.

ATP binding cassette transporters and uridine diphosphate glycosyltransferases are ancient protein families that evolved roles in herbicide resistance through exaptation

The paper investigates the evolutionary history of ABC transporters and UGTs in Archaeplastida, showing their ancient origins and diversification, with UGTs appearing later in streptophyte lineages.

ROP GTPase regulates polarised cell growth and cell division orientation during tissue development and organogenesis in Marchantia polymorpha

A versatile CRISPR-based system for lineage tracing in living plants

The paper introduces a CRISPR-based lineage tracing system in plants that uses Cas9 to correct a frameshift mutation, enabling fluorescent labeling of cell lineages without altering plant phenotypes.

Transposons repressed by H3K27me3 were co-opted as cis-regulatory elements of H3K27me3 controlled protein coding genes during evolution of plants

The paper investigates how H3K27me3 marks transposons in different plant lineages and shows that these elements were co-opted as cis-regulatory elements for PRC2-controlled genes during evolution.

Meristem dormancy in a dichotomous branching system is regulated by a liverwort-specific miRNA and a clade III SPL gene in Marchantia polymorpha

This study identifies a liverwort-specific miRNA and a clade III SPL gene that regulate meristem dormancy in Marchantia polymorpha, revealing conserved and divergent mechanisms of phytochrome signaling in branching architecture.

Reduced coenzyme Q synthesis confers non-target site resistance to the herbicide thaxtomin A

This study identifies loss-of-function mutations in MpRTN4IP1L as a novel mechanism of non-target site resistance to the herbicide thaxtomin A in Marchantia polymorpha.

Transcriptome changes in chlorsulfuron-treated plants are caused by acetolactate synthase inhibition and not induction of a herbicide detoxification system in Marchantia polymorpha

This study shows that chlorsulfuron-induced transcriptome changes in Marchantia polymorpha are due to acetolactate synthase inhibition, not a detoxification response.

Genes encoding cytochrome P450 monooxygenases and glutathione S-transferases associated with herbicide resistance evolved before the origin of land plants

The paper identifies that CYP and GST genes associated with herbicide resistance evolved in the common ancestor of land plants and streptophyte algae, with gene duplications increasing their numbers in land plants.

A potent SARS-CoV-2 neutralizing antibody recognizing a conserved epitope with broad mutant variant and SARS-CoV activity.

This paper identifies a SARS-CoV-2 neutralizing antibody, ABP-310, that is effective against multiple variants including Omicron and SARS-CoV, suggesting broad therapeutic potential.

An evidence-based 3D reconstruction of Asteroxylon mackiei the most complex plant preserved from the Rhynie chert

This paper presents a 3D reconstruction of Asteroxylon mackiei, revealing its body plan and developmental processes using fossil data.

Gene expression data support the hypothesis that Isoetes rootlets are true roots and not modified leaves

An Evolutionarily Conserved Receptor-like Kinases Signaling Module Controls Cell Wall Integrity During Tip-Growth

The paper identifies a conserved MLR/PTI1-like signaling module in M. polymorpha and A. thaliana that regulates cell wall integrity during tip-growth.

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.

Neofunctionalisation of basic helix loop helix proteins occurred when plants colonised the land

The paper investigates the evolutionary origin of RSL genes in land plants by comparing their function with a related gene in charophycean algae, suggesting neofunctionalisation occurred after land colonization.
