A newly discovered species raises hope that some native British habitats could be restored.

From the dating of 132 ancient whole-genome duplication events across 470 angiosperms, paleopolyploidization events cluster around pivotal periods of environmental upheaval and extinction, notably the...

Interview with Junko Kyozuka, who studies plant growth with a focus on branching at Tohoku University.

Terrestrial vascular plants operate under negative water potential, which results in hydraulic tension in the vascular system. Vascular tension varies with transpiration and soil drying and is regulat...

Rhizoid specification in Marchantia polymorpha gemmae involves lateral inhibition mediated by the microRNA FRH1, which represses the rhizoid-specific …

Land plants (embryophytes) are multicellular eukaryotes with a remarkable capacity to grow continuously during their life span. They achieve this by m…

Soil compaction traps ethylene around roots, which causes transcriptional upregulation of Auxin Response Factor1, resulting in decreased root cortical cell wall thickness and thereby promoting root ra...

In roots, cell-type-specific differentiation enables specialized responses to environmental stress. The cortex, located between the vasculature and epidermis, is a key site for stress-responsive modi....

The branching pattern of the Arabidopsis root is established as early as in the distal tip of the primary root.

For sexually reproducing organisms to pass on their genetic information, progeny must successfully establish. Various life history strategies have evolved, using either dispersal of large numbers of p...

A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.

The periderm layers of plants form an outer protective barrier. If the periderm is broken, movement of the gases ethylene and oxygen triggers a healing process.

The receptor-like kinase HER7 is required for sex determination in the homosporous fern Ceratopteris richardii.

Nature - Single-cell RNA sequencing and spatial transcriptomic approaches reveal major expression changes in outer root cell types when grown in soil versus gel conditions, and also uncover how...

Gene expression and complex phenotypes are determined by the activity of cis-regulatory elements. However, an understanding of how extant genetic variants affect cis regulation remains limited. Here, ...

Plant root systems play a crucial role in taking up water and nutrients, as well as in facilitating symbiotic partnerships with microorganisms like rhizobia and mycorrhizae that enhance nutrient fixa...

Nature Plants - De Roij et al. map a minimal region for auxin response factor (ARF) degradation in Marchantia and reveal that ARF instability predates the emergence of the auxin response. This...

Global N4 cytosine methylation in Marchantia polymorpha sperm regulates gene expression and promotes sperm fertility.

How plants first invented seeds is a longstanding unresolved evolutionary question. Seed-bearing plants arose from within seedless vascular plants, with ferns as their closest relatives, but how the s...
