When is a lichen not a lichen?
Chen et al. (2025) introduce a groundbreaking cyanobacterium-fungus symbiosis termed phyllosymbium, challenging traditional lichen concepts. In this unique association, the cyanobacterium envelops the fungus, displaying an unexpected structure. This discovery raises important questions about mutual benefits and interactions, broadening our understanding of symbiotic relationships in nature.

The roles of sharp structures in plant survival strategies
The post explores the defensive roles of thorns, spines, and prickles in plants. It discusses research showing that thorns can deter herbivores, their potential aposematic coloration, and the hypothesis that they may inject pathogens into herbivores, thus adding a biological warfare aspect to their defense mechanisms.

Gene-editing, taking the ouch out of touch
The post provides background on plant defenses against herbivores, focusing on prickles, thorns, and spines. It then looks in detail at work by Satterlee et al. who used CRISPR-Cas9 techniques to create prickle-free variants of aubergine and other Solanum species, potentially transforming agricultural practices and enhancing food safety during harvesting…

Botanical potpourri No. 1
This post explores various plant-based topics, focusing on newly discovered species and their significance. It highlights the discovery of the “Ghost palm” and critically endangered species. Additionally, it discusses forensic botany’s role in uncovering historical uses of plants and the ecological impact of migrating butterflies potentially spreading fungal diseases.

Exploring spirals in nature: The maths behind plant growth
The book “Do plants know math?” by Stéphane Douady et al. explores the mathematical principles behind plant spirals, particularly the arrangement of leaves. Not restricted to the maths, it present a rich blend of history, science, and practical activities, to show how scientists, over several centuries, studied – and eventually…

Botanical Origins of Modern Medicines
“Modern medicines from plants,” edited by Henry Oakeley, explores over 50 plants integral to modern prescription drugs. It chronicles the historical use and transition of these plants into medical treatments, detailing the origin stories of various drugs. The book is informative, well-illustrated, and a significant contribution to understanding plant-based medicines.
