Functional roles of microbial symbionts in plant cold tolerance
Acuña-Rodríguez, Ian S.; Newsham, Kevin K.; Gundel, Pedro E.; Torres-Díaz, Cristian; Molina-Montenegro, Marco A. (2020)In this review, we examine the functional roles of microbial symbionts in plant tolerance to cold and freezing stresses. The impacts of symbionts on antioxidant activity, hormonal signaling and host osmotic balance are ...

The "Trojan horse" strategy: seed fungal endophyte symbiosis helps to explain the invasion success of the grass, Poa annua, in maritime Antarctica
Molina-Montenegro, Marco A.; Ballesteros, Gabriel I.; Acuña-Rodríguez, Ian S; Pertierra, Luis R.; Greve, Michelle; Richardson, David M.; Convey, Peter; Biersma, Elisabeth M.; Goodall-Copestake, William P; Newsham, Kevin K. (2023)Aim: Poa annua L. (annual bluegrass) is presently the sole invasive vascular plant spe-cies to have successfully established in Maritime Antarctica, where it poses a sig-nificant conservation threat to native plant species. ...

The role of the soil microbiome in the colonisation of glacier forefields by Antarctic pearlwort (Colobanthus quitensis) under current and future climate change scenarios
Acuña-Rodríguez, Ian S; Newsham, Kevin K.; Convey, Peter; Biersma, Elisabeth M.; Ballesteros, Gabriel I.; Torres-Díaz, Cristian; Goodall-Copestake, William P; Molina-Montenegro, Marco A. (2024)Glacier retreat in cold regions exposes new terrain for plant colonization. However, the roles of soil microbiomes in plant establishment and performance on newly-exposed forefields have rarely been assessed. Here, we ...
