Review: How the extracellular matrix of streptophyte algae contributed to plant terrestrialization
Plant Science Research WeeklyCompared to their aquatic relatives, early land plants faced many challenges, such as a lack of buoyancy, harmful UV light, the challenge of nutrient uptake, and the need to avoid desiccation. In a fascinating review (part of the Plant Physiology focus collection on early land plant evolution), Domozych…

Review: How WOXs regulate regeneration in land plants
Plant Science Research WeeklyPlants cannot escape a bite from herbivore or being cut by a lawn mower, but they can regrow new leaves or even entire stems after damage. From simple mosses to giant sequoia trees, the process of building a new organ after wounding may be more similar than we previously thought. Key players in this…

Rapid shifts in the patterns of gene expression shapes flowering plant diversity
Plant Science Research WeeklyFlowering plants are the most widespread group of plants, occupying almost every environment on our planet. They play important roles in maintaining the earth’s biodiversity and have a remarkably high rate of diversification. What’s always puzzled scientists is how they became so incredibly diverse.…

The shape of adaptation: Evolution of venation patterns in plants
Plant Science Research WeeklyLeaf venation patterns display remarkable diversity across both living and fossil plant lineages, yet key questions remain about when and how these architectural differences emerged and what functional roles they serve. In their recent review, Mantos et al. explored the evolutionary history of venation…

Review: Cycads, chemicals, and coevolution
Plant Science Research WeeklyCycads are an ancient lineage of gymnosperms with fascinating ecological interactions. In a recent review, Salzman et al. examine the various adaptations of cycads, from attracting pollinators to repelling parasites, focusing on the roles of their wide array of specialized metabolites. A somewhat unique…

When form fits function: the value of root diversity to survival
Plant Science Research WeeklyFor a plant, form is function. Despite the diversity of forms that exist in nature, plant root diversity is notoriously understudied compared to their aerial counterpart. This review by Ramachandran and Ramirez et al. aims to revitalize the field of root form-function research by accentuating the vast…

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…

The ”hourglass” model of embryogenesis extends to brown algae
Plant Science Research WeeklyThe hourglass model of embryogenesis was proposed in the 1990s, and extended to green plants and fungi in the 2010s. During animal embryogenesis, the very earliest stages (post fertilization) are morphologically quite different from each other, and the later stages are quite different, but in the middle…

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…
