Special Issue of Current Biology on plant evolution
Plant Science Research WeeklyCurrent Biology has an excellent special issue on plant evolution full of fascinating articles. As an example, a Primer by Zhuo Feng looks at how plants were catastrophically impacted by the end-Permian mass extinction event approximately 250 million years ago. The fossil record from the Cathaysian…

Review: How plants repurposed cytokinin signaling for life on land
Plant Science Research WeeklyWhen plants first moved onto land, they encountered challenges that aquatic ancestors never faced, including heat, dehydration, and rapidly changing environmental conditions. This review by Wang et al., explores how cytokinin signaling, a pathway best known for regulating plant growth and development,…

Perspective: PLANeT, an exciting plan to fill the knowledge gaps in plant phylogenomics
Plant Science Research WeeklyWe are living at a time where insights into plant diversity, function, and evolution are being revealed at an unprecedented rate, thanks largely to the ability to readily sequence and assemble genomes. A new Perspective by Want, along with a large, international group of co-authors, sets out an exciting…

New tools to study an old mycorrhiza
Plant Science Research WeeklyI love learning about the many molecular adaptations that allowed plants to adapt to life on land, and particularly have enjoyed sharing the iconic micrograph from Remy et al (1994) that shows a 400 year old arbuscular mycorrhiza of the fungus Glomeromycotina inside a cell of Aglaophyton major. Now,…

From water to land: What bryophytes reveal about plant evolution and adaptations
Plant Science Research WeeklyThe transition of plants from aquatic to terrestrial environments occurred approximately 400 million years ago, leading to the diversification of two major lineages: tracheophytes (vascular plants) and bryophytes (non-vascular plants). While most studies on plant adaptation to environmental stressors…

Spotlight: The role of fossils for reconstructing the evolution of plant development
Plant Science Research WeeklyI suspect if we asked someone to describe a fossil we’d hear a lot about dinosaur bones. Certainly, science museums are full of fossilized animal remains, which have greatly informed our understanding of animal evolution. Plant fossils similarly are rich sources of information about plant evolution…

Comparative transcriptomics in ferns provide a framework for their unique evolutionary path
Plant Science Research WeeklyFerns are important and diverse land plants but are also known for their exceptionally large genomes. A new study by Ali et al. presents an extensive analysis of fern genomics through RNA-sequencing of 22 representative fern species. The study identified 18 whole-genome duplications across different…
