A first insight into the structure and function of rhizosphere microbiota in antarctic plants using shotgun metagenomic
Molina-Montenegro, Marco A.; Ballesteros, Gabriel I.; Castro-Nallar, Eduardo; Meneses, Claudio; Gallardo-Cerda, Jorge; Torres-Díaz, Cristian (2019)Antarctic vascular plants such as Deschampsia antarctica (Da) could generate more suitable micro-environmental conditions for the establishment of other plants like Colobanthus quitensis (Cq). Although positive plant–plant ...

Development and application of novel SSR markers to assess the genetic diversity and population structure of phacelia secunda along an altitudinal gradient in the central Chile Andes
Torres-Díaz, Cristian; Ortíz-Sepúlveda, Ana; Valladares, Moisés A.; Farias-Cantillana, Darío; Molina-Montenegro, Marco A.; Ballesteros, Gabriel I. (2025)Phacelia secunda J.F. Gmel. (Boraginaceae) is a widely distributed insect-pollinated perennial herb. In central Chile (33° S), it occurs from the sea level up to 3600 m in the Andes, exhibiting broad morphological variation. ...

Extreme environments as sources of fungal endophytes mitigating climate change impacts on crops in mediterranean-type ecosystems
Ballesteros, Gabriel I.; Newsham, Kevin K.; Acuña-Rodríguez, Ian S.; Atala, Cristian; Torres-Díaz, Cristian; Molina-Montenegro, Marco A. (2024)Societal Impact Statement Climate change is predicted to increase drought and soil salinity in Mediterranean-type ecosystems (MTEs), posing a significant threat to global food security. Genetic modification of crops to ...

In silico analysis of metatranscriptomic data from the antarctic vascular plant Colobanthus quitensis: responses to a global warming scenario through changes in fungal gene expression levels
Ballesteros, Gabriel I.; Torres-Díaz, Cristian; Bravo, León A.; Balboa, Karen; Caruso, Carla; Bertini, Laura; Proietti, Silvia; Molina-Montenegro, Marco A. (2020)Maritime Antarctica is one of the most stressful environments for plant life worldwide. However, two vascular plant species (Deschampsia antarctica and Colobanthus quitensis) have been able to colonize this hostile ...

Integration of physiological and molecular traits would help to improve the insights of drought resistance in highbush blueberry cultivars
Balboa, Karen; Ballesteros, Gabriel I.; Molina-Montenegro, Marco A. (2020)Water deficit or drought is one of the most severe factors limiting plant yield or fruit quality. Thus, water availability for irrigation is decisive for crop success, such as the case of highbush blueberry (Vaccinium ...

Seed fungal endophytes promote the establishment of invasive Poa annua in maritime Antarctica
Ballesteros, Gabriel I.; Acuña-Rodríguez, Ian S.; Barrera, Andrea; Gundel, Pedro E.; Newsham, Kevin K.; Molina-Montenegro, Marco A. (2022)Background Invasive plants may displace native species. This is the case for Poa annua, the only non-native plant species successfully established in Maritime Antarctica. Nonetheless, it is uncertain which factors drive ...

Symbiotic interaction enhances the recovery of endangered tree species in the fragmented maulino forest
Torres-Díaz, Cristian; Valladares, Moisés A.; Acuña-Rodríguez, Ian S.; Ballesteros, Gabriel I.; Barrera, Andrea; Atala, Cristian; Molina-Montenegro, Marco A. (2021)Beneficial plant-associated microorganisms, such as fungal endophytes, are key partners that normally improve plant survival under different environmental stresses. It has been shown that microorganisms from extreme ...

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 mountain papaya may be a possible reservoir of the Kashmir bee virus
Faúndez-Acuña, Jorge Y.; Verdugo, Diego; Vergara, David; Olivares, Gerardo; Ballesteros, Gabriel I.; Quiroz, Karla; Villarroel, Carlos A.; González, Gloria (2025)
Background The Kashmir bee virus (KBV) infects many species of Hymenoptera, including bees, wasps, and other pollinators, potentially contributing to honeybee population declines. KBV can cause death of bees. KBV can ...

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 ...
