Opinion: Genomic studies hint at what makes a tree a tree
Plant Science Research WeeklyThis is such an engaging and though-provoking review article. I’d love to ask a group of students to think about what makes a tree a tree, including such questions as: How do we define trees? Do woody plants share a single origin? How many angiosperms are woody? The answer to those questions and more…

The Spirogyra genome and the origin of that spiral chloroplast
Plant Science Research WeeklyI expect we’ve all been captivated by images of the beautiful spiral chloroplasts in the Spirogyra genus of filamentous algae, and who could forget that name? A new paper by Goldbecker et al. presents the genome of Spirogyra pratensis, uncovering not only some insights into this remarkable structure,…

Repeated evolution of flowers specialized for buzz pollination
Plant Science Research WeeklyIf you’ve ever looked closely at a tomato flower, you might have noticed that its anthers cluster together in the center of the flower, making the pollen inaccessible to most insects. Tomato flowers are an example of a buzz pollinated flower, in which the pollen is released by the physical shaking…

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…

Perspective. The art of drying gracefully: The future for desiccation research
Plant Science Research WeeklyIn their perspective article, “Life on the dry side: a roadmap to understanding desiccation tolerance and accelerating translational applications,” Marks et al. outline the current state and future promise of desiccation tolerance research. They define desiccation tolerance as “the ability to dry…

Double trouble: The Solanum pan-genome shows gene duplication complicates predictability
Plant Science Research WeeklyA pan-genome has been assembled for the Solanum genus, which contains many diverse and economically important crops including potato, tomato, and African eggplant. Genomes were assembled for 22 species, and genes were predicted based on previous reference genomes and from RNA sequences across multiple…

Shaping pathogenicity: How CRISPR-Cas loss fuels Xanthomonas evolution
Plant Science Research WeeklyPathogens have evolved diverse infection strategies governed by virulence factors, often targeting specific host organs or tissues. Genome fluidity plays a crucial role in enabling microbial pathogens to adapt to the dynamic selection pressures imposed by co-evolution with their hosts. In a recent study,…

Streamlining the immune system: How plants adapt to reduced pathogen pressure
Plant Science Research WeeklyAlthough plants are sessile organisms unable to escape pathogen invasions, they are well equipped with defense mechanisms. Cell surface-localized pattern-recognition receptors (PRRs) detect extracellular signals and initiate pattern-triggered immunity (PTI), while nucleotide-binding leucine-rich repeat…

Many plant transcription factor families have evolutionarily conserved binding motifs
Plant Science Research WeeklyThe regulated expression of genes is fundamental to all biological processes, including development, cell growth, and responses to environmental signals. Transcription factors (TFs) are sequence-specific DNA-binding proteins that play a central role in transcriptional regulation by directly interacting…
