The ANTIOX group is happy to announce that our undergrad and master students are defending their final projects this week to complete their studies.BSc and MSc students were able to perform their final degree projects at the ANTIOX group, where they could design and execute their hypothesis and ideas.
You can check the timing and sites for their talks on the following image, so that you don’t miss any of their interesting work.
A recent publication in Nature Plants describes that ancient trees play an essential role in forest dynamics and provide a great genetic and biological diversity which is essential in the global population of this ecosystem.
The work, which has been conducted by the ANTIOX principal investigator Prof. Sergi Munné-Bosch from the Faculty of Biology, the Biodiversity Research Institute (IRBio) and the Institute for Nutrition and Food Safety Research (INSA) of the University of Barcelona, in collaboration with the experts Chuck Cannon, director of Center for Tree Science – The Morton Arboretum (United States), and Gianluca Piovesan, lecturer of Landscape, Environmental Planning and Design at the University of Tuscia (Italy), examined the demographical patterns that emerge from ancient forests over thousands of years, and a small proportion of trees result as life history ‘lottery winners’.
The University of Barcelona highlighted this work in one of their latest news because of the impact in our knowledge in forest ecosystems (access here to news).
We provide you in the following link the full published work: Nature Plants – Old and ancient trees are life history lottery winners and vital evolutionary resources for long-term adaptive capacity.
Understanding plant life might be challenging if a space and time framework is not considered. Our most recent review by Prof. Sergi Munné-Bosch published in Trends in Plant Science emphasizes the methodological limitations of current work to put in perspective that space and time are key factors to consider if we want to understand plant physiological responses.
This work appeared in the news of the University of Barcelona because of the relevance for all scientists since our research should be able to understand life in all its complexity (follow this link to the full new).

Good news for the ANTIOX group since one of our postdoctoral researchers, Erola Fenollosa has been awarded with a Margarita Salas research grant from the Spanish Goverment to perform a two-year postdoc between the University of Barcelona with the ANTIOX group of Sergi Munné-Bosch and Oxford University working with Roberto Salguero at The SalGo Team.
With this grant, Erola is expanding her research in invasive plants and ecological modelling which started as part of her doctoral work.
We wish her the best for this new chapter and a bright future with her research!
This summer 2021 we received funding for developing a divulgation project about the exotic and potentially invasive plant species in Barcelona. This project is entitled “Act on time: potentially invasive species in the city of Barcelona / Actuem a temps: espècies susceptibles a ser invasores a la ciutat de Barcelona” and has been funded by the Barcelona City Council.
The main objective of this project is to quantify and divulgate about the threat that potentially invasive species suppose to the quality of the green infrastructure of Barcelona. Under this aim we have firstly determined the top 10 most potentially dangerous plant species already found in the city considering its inclusion in the list of potentially invasive species in Spain, its extension and described impacts in other regions of the world.
Those ten potentially invasive species in the city of Barcelona include herbs, shrubs and trees widely used as ornamental plants that should be substituted by other alternatives. Moreover, we are visiting schools and high schools to explain the threat that invasive species suppose to global biodiversity and to divulgate the list of 10 potentially invasive species in Barcelona proposting other alternatives. We have created multiple divulgation materials and workshops for children and teenagers but also for the general audience to know those species and learn more about their impacts.
Multiple members of the ANTIOX-Ecophys grup take part of this project, counting on the long research team experience in invasive plants research through different research lines (i.e. Physiology of invasive plants, ecological modelling of invasive plants).

The bachelor students performing their internship at the ANTIOX group are reaching their final stage of their undergraduate program by defending their final degree project (TFG) this July 2021. All projects have been related with the plant ecophysiology research field, but we had a great diversity of exciting themes!
The student Júlia Capellades has studied the impacts of an exotic and potentially invasive species in the high biodiversity area of L’Empordà unraveling its interactions with other native and exotic species. Her TFG is entitled “Study of the impact of Aptenia cordifolia in l’Empordà” and has been developed under the supervision of Dr. Erola Fenollosa and Prof. Sergi Munné-Bosch, where she has gained new insights into the impacts of exotic species over native communities.
Our students Patricia Fernández and Ot Pasques developed their final projects under the supervision of Dr. Melanie Morales and Prof. Sergi Munné-Bosch. Patricia developed her TFG entitled “Multiple plant species stress responses to different abiotic stresses – A Mediterranean coast and high mountain study“. Ot’s project is entitled “Stress tolerance mechanims of Plantago lanceolata on an altitude gradient at the Pyrinees“. On both projects the students combined field work with laboratory analyses to gain insight on plant’s adaptative mechanisms to multiple abiotic stressors under natural conditions.
Their project defense is taking place at Biology’s Faculty of the University of Barcelona from 12th to 14th July. We wish them the best luck for their defense and their projects ahead!
The director of the ANTIOX Team, Prof. Sergi Munné-Bosch has been invited to an oral conference at the XXIV Meeting of the Spanish Society of Plant Biology and the XVII Spanish Portuguese Congress on Plant Biology which will be held online from 7 to 9 July 2021 (BP 2021). This conference is organized by both the Spanish Society of Plant Biology (SEFV) and the Portuguese Society of Plant Physiology (SPFV) and the University of Vigo.
In words of the organizing committe: “BP2021 is a biannual congress which, on its seventh edition, will held 12 scientific sessions that cover several fields related to the functioning of plants and their interaction with other organisms in the ecosystem. Each session will focus not only basic aspects (mineral nutrition, growth and development, phytohormones, short and long distance transport, photosynthesis, etc.) and applied aspects (ecophysiology and plant stress, secondary metabolism, etc.) of plant biology, but also approach the main challenges we, from the study of the plant, face in today’s society (climate change, agricultural production, etc.)”.
Prof. Sergi Munné-Bosch will contribute to the 5th session of Plant stress and ecophysiology with an oral conference entitled: “Bidirectional link between vitamin E and oxylipins in plants: a key to better understanding plant tradeoffs?”. The whole program and schedule of the conference can be found in the BP2021 program. Find also more information and inscriptions here.
This June 2021, three students of the Marine Sciences Degree at the Geology Faculty: Cris Aldana, Sandra Rasero and Estrella Fernández are defending their Final Degree Project (TFG), which has been developed in the ANTIOX Team, under the supervision of Prof. Sergi Munné-Bosch and Andrea Casadesús.
The three students have developed different projects under the research line of Ecophysiology of marine and wetland plants exploring the diversity and stress responses of different marine and wetland plants, which will give more insight on the importance of those very rich ecosystems and understanding their response to stressors such as temperature extremes, which could help us to better understand the limits of these ecosystems and improve our management of vulnerable Mediterranean ecosystems.
Cris Aldana developed a study entitled “Differences in drought and photo-oxidative stress markers in the Alismatales order”. Estrella Fernández study is entitled “Oxidative stress and Vitamin E function in Cymodocea nodosa under low temperatures”, and Sandra Rasero study is entitled “Tocochromanols in Cymodocea nodosa: effects of high temperatures and inter-individual variability”.
The TFG’s defence will take place in the University of Barcelona the 21th of June at 15h. We wish them the best in this defence and the following projects that this year will bring.
Regarding to the “International Day of Women and Girls in Science”, our postdoctoral researcher Melanie Morales participates at the 3rd edition of the #100tífiques event on February 11th, 2020. Her talks will be aimed at an audience aged 11-12 years old (6è primary school and 1st secondary School) to share her own experience as a woman scientist in plant biology and, specifically, raise awareness among children about the climate change effects on Antarctic plants.
The #100tífiques is an initiative of the Catalan Foundation for Research and Innovation (FCRI) and the Barcelona Institute of Science and Technology (BIST), in collaboration with the Department of Education of the Generalitat de Catalunya. The aim of this project is to make visible and highlight the relevance and strategic role of women in science and technology, while encouraging joint actions between academia and business scientists. The program aims to foster a more direct and reciprocal relationship between science and society, and especially to increase the awareness of this group and expand its space.
As a member of our research group, we are enthusiastic to participate in this kind of initiative to promote and divulgate science among the social community, so reach and encourage girls to become super women scientists.
Andrea Casadesús and Prof. Sergi Munné-Bosch have recently contributed to impact and ecophysiology of holoparasitic plants in Mediterranean agroecosystems. This month, the article “Holoparasitic Plant–Host Interactions and their Impact on Mediterranean Ecosystems” by the two authors has been published in Plant Physiology. This review highlights how improving our knowledge of holoparasitic–host interactions in Mediterranean-type ecosystems will help us to better manage parasitic plants, both in agricultural and natural ecosystems.
Moreover, the PhD Student at the ANTIOX Research Team Andrea Casadesús, first author of this article, has been recognized by the Plantae community, where she exposed brief bio and the origins of her interest in plant physiology.
This January a new review article from the ANTIOX Team has been published in Plant Physiology. This first new year article is entitled Hormonal Impact on Photosynthesis and Photoprotection in Plants. Through multiple tables and very illustrative figures, this review presents the current knowledge on this issue and highlights the role of hormonal crosstalk in regulating multiple functions beyond stomatal closure, including redox signalling under optimal and stressful conditions.
It has been written by the two members of the ANTIOX Team Dr. Maren Müller and Prof. Sergi Munné-Bosch. Over more than a decade, our group has developed and improved a rapid and sensitive UPLC/ESI-MS/MS method to the simultaneous quantification of all known phytohormone classes, including: cytokinins, auxins, ethylene, gibberellins, abscisic acid, brassinosteroids, jasmonates, salicylic acid, and strigolactones.
Dr. Maren Müller is currently leading the research line from the ANTIOX Team of Interaction profiling of phytohormones, that focuses on the interaction and profiling of phytohormones to gain new insights into their function as signalling molecules regulating plant physiology, development and adaptation to environmental stimuli.
The ANTIOX team is thrilled to announce that our principal investigator Prof. Sergi Munné-Bosch has been awarded with the ICREA Academia prize for his research career. The Catalan Institute of Research and Advanced Studies (ICREA) acknowledges with this prize researchers in the public system of Catalan universities performing outstanding research with the objective to keep this talent in Catalonia by funding 5 years of research. Our principal investigator Prof. Sergi Munné Bosch has been one of the selected researchers, along with 17 men and 12 women in the research areas of experimental sciences and mathematics, technology and engineering, life sciences and medicine, human and social sciences and behaviour (press release here). This award allows Prof. Sergi Munné-Bosch and the ANTIOX team to grow and develop further research in the areas of plant ecophysiology and agri-food biotechnology.
We also want to acknowledge the team effort for obtaining this prize by posting the ANTIOX group photos of the latest years:

This January 2021, Lara Fuertes is defending her Final degree project (TFG), which has been developed under the supervision of Dr. Marta Pintó-Marijuan (from the ANTIOX Team at the Universitat de Barcelona) and Dr. Aaron Pérez (from the Universitat de Vic), and in collaboration with the CREAF (Centre de Recerca Ecològica i Aplicacions Forestals).
Lara is studying Biology at the University of Vic and her TFG focuses on the physiological response of twelve Mediterranean species to drought stress and its recovery, including the comparison of a first and second stress period to evaluate the existence of memory processes. The results she has obtained will allow the definition of which species can tolerate drought stress and show a higher recovery capacity, but also describes the existence of physiological memory in some species, which will undoubtably contribute to a better understanding of the recurrent drought adaptation.
Lara’s TFG defence will take place in the Universitat de Vic the 29th of January at 9.45h. We wish her the best in this defence and the following projects that this year will bring.
Chloroplasts are important hubs for the integration of developmental and stress signals in plant cells, but mechanisms related to reception and transmission of these signals are still poorly understood. In this context, the international journal Redox Biology has recently published a graphical review article entitled Oxylipins in plastidial retrograde signaling by our ANTIOX members Dr. Paula Muñoz and Prof. Sergi Munné-Bosch, where they highlight the relevant role of these compounds derived from the oxidation of polyunsaturated fatty acids in plastidial retrograde signaling to highlight future avenues for research.
In the mentioned review, our ANTIOX members emphasize plastid diversity regarding developmental stage, plant organ or stressful conditions, where the production of oxylipins might be affected and become intermediate signals or hormonal elicitors to facilitate acclimation or developmental responses. The review article also describes the latest knowledge related to signal transduction of reactive electrophilic species as secondary lipid peroxidation products which have been long overlooked when describing oxylipin-related signal transduction and the problems associated with the study and interpretation of the production of these molecules in plant cells.
The recent collaboration with Dr. Fabio Pasin has resulted in a new publication this September 2020 in Plant Communications with the contribution of three members of the ANTIOX Team: Dr. Maren Müller, David H. Fresno and Prof. Sergi Munné-Bosch.
The publication is entitled “Abscisic Acid Connects Phytohormone Signaling with RNA Metabolic Pathways and Promotes an Antiviral Response that Is Evaded by a Self-Controlled RNA Virus” and shows that abscisic acid is an active player in plant immunity to plant pathogenic viruses of the genus Potyviridae by affecting host RNA metabolism. These findings shed a light on the importance of this phytohormone in plant responses to viruses, whose role in this type of immunity had been overlooked until now.

This August we received the postdoctoral researcher Dr. Melanie Morales in the Antiox-Ecophys research Team. She has been awarded with the 3-year postdoctoral fellowship Beatriu de Pinós Research Program funded by the European Commission in the H2020 and Marie Skłodowska-Curie actions (MSCA) framework. This grant is coordinated by the Agència de Gestió d’Ajuts Universitaris i de Recerca in Catalonia, Spain.
This fellowship allowed her to rejoin the ANTIOX Ecophys group this year, in which she developed her Ph.D. in Plant Biology (2012-2015), and where she will be leading from now on the 2-research lines from the ANTIOX Ecophys Group: Abiotic Stress Tolerance and Sexual Dimorphism.
It is for us a great pleasure to welcome such great researcher and old friend in our group. Welcome back Dr. Morales!
Our member of the Antiox-Ecophys group Erola Fenollosa is reading her thesis entitled ‘Stress, reproduction and senescence for invasive success: the study case of Carpobrotus edulis’.

Sergi Munné-Bosch has recently contributed to the immortal debate of eternal living. This month, the forum article “Long-Lived Trees Are Not Immortal” by Sergi Munné-Bosch has been published in Trends in Plant Science. This article is a response to the article published this January by Li Wang et al. in PNAS and points out that although long-lived trees may have long lives, they are also subjected to physiological limits that constrain their immortality, and in the end they all will die.
The article has been highly supported by the media worldwide besides the University of Barcelona News and has been included in different prestigious newspapers such as The New York Times in USA, Daily Mail and Telegraph in UK and La Vanguardia in Spain.
We are delighted to announce that the first manuscript from the PLANTPOPNET network has been published this month in PNAS. The article is entitled “Global gene flow releases invasive plants from environmental constraints on genetic diversity” and Annabel L. Smith, the first author of the article, presents worldwide demographic and genetic data of the invasive plant Plantago lanceolata. Within the almost 50-authors list, Sergi Munné-Bosch and Melanie Morales, from the ANTIOX-Ecophys Team, have contributed collecting demographic data within the P. lanceolata native range.
The article is strongly significant not only in plant demography studies but also contributes to understand the dynamics behind biological invasions, as the PLANTPOPNET global dataset of P. lanceolata demography and genetic diversity revealed that long-distance dispersal and repeated introductions by humans have shaped adaptive potential of this invasive species by promoting genetic stock mixing from multiple populations.

Last week part of the antiox-ecophys group attended the VIII Spring Forest Ecophysiology Meeting 2018 in Madrid (Coloquio de primavera sobre ecofisiología forestal). The meeting took place on 25-27 April in the breathtaking forests of Cercedilla (Madrid, Spain).
This event brings together plant ecophysiologists from Spain allowing them to share not only their latest findings but also their thoughts about some controversial issues around the ecology and physiology of the plant kingdom.
In this occasion, two of our PhD Students, Marina Pérez and Erola Fenollosa, presented their work during one of the sessions. Moreover, Sergi Munné-Bosch inspired and led a debate around plant longevity and senescence.
As a closure of last semester, some of our ANTIOX group members took part in the Three Minute Talk (3MT) competition, held at the Faculty of Biology. Hosted by the department of Evolutive Biology, Ecology and Environmental Sciences (BEECA), 3MT gathered all the exciting research conducted by the current department constituents who had to effectively present their thesis to the audience in only three minutes.
Representing the ANTIOX group, Marina introduced her research on paraheliotropism of Cistus albidus during daily and seasonal periods. Likewise, Erola presented her study of oxidative biomarkers on Carpobrotus edulis, an invasive plant in the Catalan region. Finally, Paula explained her research on photo-oxidative stress and redox regulation on fruits, commercial flowers and dioecious plants. The public and a special jury constituted by members of all groups from the department could choose which three minute speech was the best and we’re very proud to announce that Erola won the first prize with her creative 3MT about invasive plants.
We hope to keep participating in the upcoming editions!
