Development and evaluation of cross-linked alginate–chitosan–abscisic acid blend gel
Bustos, Daniel; Guzmán, L.; Valdés, Oscar; Muñoz-Vera, Marcelo; Morales-Quintana, Luis; Castro, Ricardo I. (2023)Abscisic acid (ABA) has been proposed to play a significant role in the ripening of noncli macteric fruit, stomatal opening, and response to abiotic stresses in plants, which can adversely affect crop growth and productivity. ...

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 ...

Improvement in the physiological and biochemical performance of strawberries under drought stress through symbiosis with Antarctic fungal endophytes
Morales-Quintana, Luis; Moya, Mario; Santelices-Moya, Rómulo; Cabrera-Ariza, Antonio; Rabert, Claudia; Pollmann, Stephan; Ramos, Patricio (2022)Strawberry is one of the most widely consumed fruit, but this crop is highly susceptible to drought, a condition strongly associated with climate change, causing economic losses due to the lower product quality. In this ...

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 ...

Physicochemical and computational analysis of the melamine resin derivative for the glyphosate absorption from water using Langmuir-type model
Morales-Quintana, Luis; Bustos, Daniel; Gallego, J.; Valdes, O.; Guzmán, L.; Nachtigall, Fabiane M.; Marican, Adolfo; Hernández-Rodríguez, Erix W.; Avila-Salas, Fabian; Bueno-Silva, W.; Santos, Leonardo S.; Castro, R. I. (2022)Conventional pesticides are biosynthetic chemicals that are effectively used for the control of weeds, diseases, and pests worldwide. Among them, glyphosate, one of the most commonly used broad-spectrum herbicides, might ...

Role of glycoproteins during fruit ripening and seed development
Mendez-Yañez, Angela; Ramos, Patricio; Morales-Quintana, Luis (2021)Approximately thirty percent of the proteins synthesized in animal or plant cells travel through the secretory pathway. Seventy to eighty percent of those proteins are glycosylated. Thus, glycosylation is an important ...
