'''''Dear visitor,'''''<br>
 +
<br> Welcome to the Molecular Genetics of Plant Stress Tolerance Lab (Ruben Alcazar & A.F. Tiburcio Labs) ''' at the Department of Biology, Healthcare & Environment of the University of Barcelona. <br><br>
 +
We're a recently created joint research group that investigates the '''adaptation of plants to local environments'''. We focus on the evolutionary adaptation of plant populations to '''abiotic and biotic stresses''', which are major challenges for plant survival under the current climate change predictions. Derived from our research, we investigate ways for improving stress protection.<br>

We're interested in genetics of natural variation, population genetics and molecular biology. We want to know how climate change is shaping plant's resistance and tolerance traits under a combined multidisciplinary approach. Our lab undertakes a research approach that looks for the genetic and molecular basis of naturally occurring quantitative variation in biotic and abiotic stress responses, and how these interact with the environment (genotype-by-environment interactions). This multidisciplinary approach will allow a better understanding of the natural evolution of stress pathways in plants and efficient know-how transfer to practical applications.<br>

In our lab, we make use of the extensive natural variation of [https://en.wikipedia.org/wiki/Arabidopsis_thaliana ''Arabidopsis thaliana''] populations to answer key fundamental questions:
 +
 
 +
* '''How plants adapt to local environments including the microbiota?'''
 +
* '''How plants maintain variability of genes involved in pathogen recognition and to which extent this variability is caused by the interaction with pathogens?'''
 +
* '''How the environment manipulates immune responses? How this affects the above points?'''
 +
 
 +
 
 +
To address these and other questions, we (and others) developed a new model for plant immunity studies based on the use of ''Arabidopsis'' immune-related incompatible hybrids. These are hybrids obtained by crosses of natural ''Arabidopsis'' accessions that exhibit constitutive activation of defense, stunted growth and sterility in the absence of pathogen challenge. Often, such phenotypes are temperature-dependent and suppressed at high temperature.
 +
 
 +
 
 +
These genetic interactions might unravel molecular partners required for proper modulation of defense. Some of these cases are background-dependent and therefore, likely difficult to be observed in classical reference accessions.
 +
 
 +
 
 +
Since some years, we're using the Ler / Kas-2 immune-related hybrid incompatibility as molecular model to answer some of the questions above. The Landsberg (from Gorzów Wielkopolski, Poland)/Kashmir-2 (from Kashmir mountains) incompatibility involves populations in Central Europe and Central Asia which enable to expand our analyses to population scales. We apply population genetics on top of our molecular and biochemical analyses.
 +
 
 +
 
 +
Derived from our research, we attempt to provide new strategies for crop protection at medium to long-term.

Dear visitor,

Welcome to the Molecular Genetics of Plant Stress Tolerance Lab (Ruben Alcazar & A.F. Tiburcio Labs) at the Department of Biology, Healthcare & Environment of the University of Barcelona.

We're a recently created joint research group that investigates the adaptation of plants to local environments. We focus on the evolutionary adaptation of plant populations to abiotic and biotic stresses, which are major challenges for plant survival under the current climate change predictions. Derived from our research, we investigate ways for improving stress protection.

For a more detailed view of our research, please have a look at our Research Projects and Scientific Publications sections. You can follow an updated list of our activities and publications in the NEWS section below. For any other enquires, do not hesitate to contact us directly.

1. POLYAMINE PERCEPTION AND SIGNALING

Our research laboratory has long-standing experience in the field of plant polyamines, for which we performed a number of omics approaches and established genetic evidence for their role in abiotic stress protection.


Our previous research pointed to interactions of polyamines with hormones and other stress-related metabolites. Our current goal is to investigate how polyamines are perceived by the plant, which early signaling components are involved, and how this is shaped by the environment.


We’re making use of background knowledge from different disciplines to gain insight into polyamine perception and signaling, for which little is known in plants. We’re making use of genetics of natural variation, reverse genetics, molecular biology and plant-microbe interactions to unravel how polyamines are sensed and how this relates to the local microbiota.

Our final goal is to provide novel approaches for crop protection against abiotic and biotic stresses.


2. MOLECULAR EVOLUTION OF DISEASE RESISTANCE IN PLANTS


In our lab, we make use of the extensive natural variation of Arabidopsis thaliana populations to answer key fundamental questions:

  • How plants adapt to local environments including the microbiota?
  • How plants maintain variability of genes involved in pathogen recognition and to which extent this variability is caused by the interaction with pathogens?
  • How the environment manipulates immune responses? How this affects the above points?


To address these and other questions, we (and others) developed a new model for plant immunity studies based on the use of Arabidopsis immune-related incompatible hybrids. These are hybrids obtained by crosses of natural Arabidopsis accessions that exhibit constitutive activation of defense, stunted growth and sterility in the absence of pathogen challenge. Often, such phenotypes are temperature-dependent and suppressed at high temperature.


These genetic interactions might unravel molecular partners required for proper modulation of defense. Some of these cases are background-dependent and therefore, likely difficult to be observed in classical reference accessions.


Since some years, we're using the Ler / Kas-2 immune-related hybrid incompatibility as molecular model to answer some of the questions above. The Landsberg (from Gorzów Wielkopolski, Poland)/Kashmir-2 (from Kashmir mountains) incompatibility involves populations in Central Europe and Central Asia which enable to expand our analyses to population scales. We apply population genetics on top of our molecular and biochemical analyses.


Derived from our research, we attempt to provide new strategies for crop protection at medium to long-term.
