Countdown for the thesis read of Erola Fenollosa

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’.

The thesis read will be held in our Faculty of Biology of the University of Barcelona the next 9 of September in coordination with a livestreming. Do not heasitate to contact our research group to follow the PhD defense in streaming video.

Long-lived trees immortality questioned – New publication in TIPS

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.

New publication: “Global gene flow releases invasive plants from environmental constraints on genetic diversity” from PLANTPOPNET Network

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.

The ANTIOX Team contribution to a Science TV Show

The ANTIOX Team contributed to a Science divulgation TV Show where we exposed our current research on the field of alkaloids and herbivoryAndrea casadesús and Sergi Munné-Bosch climbed the Montserrat mountains to show the individuals of Cistus albidus that we are studying and discuss about this nitrogenated molecules role in plant defense.

The report was included in the televisive Show QuèQuiCom in TV3 (the public autonomic television of Catalonia) in a special issue about the Nitrogen history, potentialities and hazards (Click here to watch the complete special issue). Take a look on the ANTIOX contribution:

Dr. Treesubsuntorn visits us in March, don’t miss his talk!

We are delighted to announce that we will be receiving the visit of Dr. Chairat Treesubsuntorn next month. Dr. Treesubsuntorn works as an Assistant Professor at the Pilot Plant Development and Training Institute (PDTI) in Bangkok (Thailand) and will present his lasts results in the field of phytoremediation

During his visit, he will give a talk entitled “Inhibition of cadmium uptake and translocation in Oryza sativa indica by using calcium-acetate and calcium-chloride: Efficiency and possible mechanisms”. The talk will take place at the Faculty of Biology on March 22nd at 12 pm, and is open to everyone interested. 

Take a dive into his publications here.

XV Phytohormones Symposium

The white-leaved rockrose (Cistus albidus) was present in the XV Phytohormones Symposium 2018. This Symposium was held last December 13-14, in Valencia (Spain). Marina Perez-Llorca, PhD Student at the ANTIOX Team, presented her last work on this species with a short talk entitled: “Inter-individual and sun orientation driven variability reveals antagonistic salicylate and jasmonate accumulation in white-leaved rockrose“.

The Symposium was organized by the Spanish Society of Plant Physiology (Sociedad Española de Fisiología Vegetal), which mingles Spanish scientists working on the physiology of plants, with different groups covering molecular and physiological aspects of it. 

 

Save the date: International Conference on Integrative Plant Physiology 2019

 The International Conference on Integrative Plant Physiology by ELSEVIER will be held in Sitges (Spain) from the 27 to 29th of October in 2019 with Sergi Munné-Bosch on the organizing committee. 

This conference will bring together specialists in plant ecology, physiology, biochemistry and molecular biology to share and discuss recent advances in plant biology with an emphasis on integrative and system-based approaches.

Save the date and submit your abstracts by 10 May 2019  to participate in the International Conference on Integrative Plant Physiology

New member of the steering committee of PLANTPOPNET

Sergi Munné-Bosch has become a member of the steering committee of the international network PLANTPOPNET – A Spatially Distributed Model System for Population Ecology, directed by Prof. Yvonne Buckley

The aim is to construct a global network that allows us to understand populations shifts in response to global change, starting with Plantago lanceolata as a model system. 

The Antiox-Ecophys Team is collaborating to PLANTPOPNET with an Add-on Study entitled: “Is oxidative stress a proxy for mortality in Plantago lanceolata?” exploring the use of oxidative stress markers to predict the death of the individual. 

Distribution of PLANTPOPNET sites globally (n=53). Grey area is the geographic range of P. lanceolata as per GBIF, BIEN & Petitpierre et al. (2012). Points represent demographic studies in the Non-Native (yellow) and Native (orange) range of P. lanceolata. Genomic data (red) has been recorded at 38 sites. 

 

 

VIII Forest Ecophysiology Meeting in Madrid

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.
