A seed-borne endophyte mediates plant drought responses and intergenerational effects on seed characteristics
Zarraga-Barco, F.; Ueno, Andrea C.; Casabella, M.P.; Casas, C.; Molina-Montenegro, Marco A.; Ramos, P.; Schnyder, H.; Gundel, Pedro E. (2024)Global warming is expected to increase drought severity in diverse environments, impacting plant performance. Plants acclimate to drought by mechanisms like stomatal closure and osmotic adjustment. Maternally inherited ...

A systematic review on the effects of Epichloë fungal endophytes on drought tolerance in cool-season grasses
Decunta, Facundo A.; Pérez, Luis; Malinowski, Dariusz P.; Molina-Montenegro, Marco A.; Gundel, Pedro E. (2021)Symptomless fungal endophytes in the genus Epichloë are repeatedly mentioned to increase tolerance of cool-season grasses to a wide range of environmental stress factors, mainly drought. However, the generality of this ...

Antarctic root endophytes improve physiological performance and yield in crops under salt stress by enhanced energy production and Na+ sequestration
Molina-Montenegro, Marco A.; Acuña-Rodríguez, Ian S.; Torres-Díaz, Cristian; Gundel, Pedro E.; Dreyer, Ingo (2020)Climatic change is pointed as one of the major challenges for global food security. Based on current models of climate change, reduction in precipitations and in turn, increase in the soil salinity will be a sharp constraint ...

Do fungal-endosymbionts improve crop nutritional quality and tolerance to stress by boosting flavonoid-mediated responses?
Morales-Quintana, Luis; Miño, Roberto; Mendez-Yañez, Angela; Gundel, Pedro E.; Ramos, Patricio (2022)Climate change is threatening human activities, but the combination of water scarcity and heat waves are particularly challenging agriculture. Accumulating literature shows that beneficial fungal endophytes improve plant ...

Editorial: molecular and biochemical effects exerted by the interaction of symbiotic microorganisms with plants to improve their response to environmental stresses
Ramos, Patricio; Gundel, Pedro E.; Pollmann, Stephan (2023) -
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 ...

Fungal endophytes enhance the photoprotective mechanisms and photochemical efficiency in the Antarctic Colobanthus quitensis (Kunth) Bartl. Exposed to UV-B radiation
Barrera, Andrea; Hereme, Rasme; Ruiz-Lara, Simon; Larrondo, Luis F.; Gundel, Pedro E.; Pollmann, Stephan; Molina-Montenegro, Marco A.; Ramos, Patricio (2020)Antarctic plants have developed mechanisms to deal with one or more adverse factors which allow them to successfully survive such extreme environment. Certain effective mechanisms to face adverse stress factors can arise ...

Fungal endophytes exert positive effects on Colobanthus quitensis under water stress but neutral under a projected climate change scenario in Antarctic
Hereme, Rasme; Morales-Navarro, Samuel; Ballesteros, Gabriel; Barrera, Andrea; Ramos, Patricio; Gundel, Pedro E.; Molina-Montenegro, Marco A. (2020)Functional symbiosis is considered one of the successful mechanisms by which plants that inhabit extreme environment improve their ability to tolerate different types of stress. One of the most conspicuous type of symbiosis ...

Getting ready for the ozone battle: vertically transmitted fungal endophytes have transgenerational positive effects in plants
Ueno, Andrea C.; Gundel, Pedro E.; Molina-Montenegro, Marco A.; Ramos, Patricio; Ghersa, Claudio M.; Martínez-Ghersa, M. Alejandra (2021)Ground-level ozone is a global air pollutant with high toxicity and represents a threat to plants and microorganisms. Although beneficial microorganisms can improve host performance, their role in connecting environmentally ...

Maternal exposure to ozone modulates the Endophyte-conferred resistance to Aphids in lolium multiflorum plants
Bubica, Ludmila M.; Ueno, Andrea C.; Di Leo, Tara D.; Crocco, Carlos D.; Martínez-Ghersa, M. Alejandra; Molina-Montenegro, Marco A.; Gundel, Pedro E. (2020)Plants are challenged by biotic and abiotic stress factors and the incidence of one can increase or decrease resistance to another. These relations can also occur transgenerationally. For instance, progeny plants whose ...

Molecular and structural characterization of expansins modulated by fungal endophytes in the Antarctic Colobanthus quitensis (Kunth) Bartl. Exposed to drought stress
Morales-Quintana, Luis; Barrera, Andrea; Hereme, Rasme; Jara, Karla; Rivera-Mora, Claudia; Valenzuela-Riffo, Felipe; Gundel, Pedro E.; Pollmann, Stephan; Ramos, Patricio (2021)Expansins are proteins involved in cell wall metabolism that play an important role in plant growth, development, fruit ripening and abiotic stress tolerance. In the present study, we analyzed putative expansins that respond ...
