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 ...

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 ...

What if the cold days return? epigenetic mechanisms in plants to cold tolerance
Hereme, Rasme; Galleguillos, Carolina; Morales-Navarro, Samuel; Molina-Montenegro, Marco A. (2021)Low temperatures are one of the most critical environmental conditions that negatively affect the growth, development, and geographic distribution of plants. Exposure to low temperatures results in a suit of physiological, ...
