Convergent losses of arbuscular mycorrhizal symbiosis in carnivorous plants. [PDF]
New PhytolSummary Most land plants form the ancient arbuscular mycorrhizal (AM) symbiosis, while carnivory is a younger trait that evolved in several angiosperm orders. The two biotic interactions similarly help plants acquire mineral nutrients, raising the question of whether they can coexist.

An arbuscular mycorrhiza from the 407-million-year-old Windyfield Chert identified through advanced fluorescence and Raman imaging. [PDF]
New PhytolSummary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

Chemical ecology of symbioses in cycads, an ancient plant lineage. [PDF]
New PhytolSummary Cycads are an ancient lineage of gymnosperms that maintain a plethora of symbiotic associations from across the tree of life. They have myriad morphological, structural, physiological, chemical, and behavioral adaptations that position them as a unique system to study the evolution, ecology, and mechanism of symbiosis.
