Mutualism and adaptive divergence: co-invasion of a heterogeneous grassland by an exotic legume-rhizobium symbiosis. [PDF]

open access: yesPLoS ONE, 2011
Species interactions play a critical role in biological invasions. For example, exotic plant and microbe mutualists can facilitate each other's spread as they co-invade novel ranges.

Serpentine Enhances Insulin Regulation of Blood Glucose through Insulin Receptor Signaling Pathway

open access: yesPharmaceuticals, 2022
Insulin sensitizers targeting insulin receptors (IR) are a potential drug for the treatment of diabetes. Serpentine is an alkaloid component in the root of Catharanthus roseus (L.) G. Don. Serpentine screened by surface plasmon resonance (SPR) technology

A common garden test of host-symbiont specificity supports a dominant role for soil type in determining AMF assemblage structure in Collinsia sparsiflora. [PDF]

open access: yesPLoS ONE, 2013
Specialization in plant host-symbiont-soil interactions may help mediate plant adaptation to edaphic stress. Our previous field study showed ecological evidence for host-symbiont specificity between serpentine and non-serpentine adapted ecotypes of ...

Adaptations to the stressful combination of serpentine soils and Mediterranean climate drive plant functional groups and trait richness

open access: yesFrontiers in Plant Science, 2023
IntroductionPlant functional traits (FTs) are important for understanding plant ecological strategies (e.g., drought avoidance), especially in the nutrient-poor soils of serpentine ecosystems. In the Mediterranean areas, such ecosystems are characterized
