'''''Dear visitor,'''''<br>
<br> Welcome to the webpage of the '''Molecular Genetics of Plant-Environment Interactions (Alcazar Lab)''' at the Department of Biology, Healthcare & Environment of the University of Barcelona. <br><br>
We're a recently created 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>

Our lab studies the genetic and molecular bases for the adaptation of plants to their local environments. We mainly focus on the adaptation to stress (abiotic and biotic) exploring the natural variation present in wild populations.
----
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.

Current projects <br>
'''Evolution of ''NB-LRR'' genes in nature, disease resistance and incompatibility  ''' <br>
<font face="calibri" style="color:#000000" font size="4"> <br>
We're currently studying the evolution of ''NB-LRR'' immune-receptor genes in nature that condition defense against evolving pathogens and how this derives in immune-driven reproductive isolation barriers within species (hybrid incompatibilities). We're particularly studying the evolution of the ''RPP1''-like cluster, which is involved in recognition of the naturally occurring ''Arabidopsis thaliana'' pathogen ''Hyaloperonospora arabidopsidis'' and frequently involved in hybrid incompatibility. Through a combined research involving molecular biology,  population genetics and biochemical approaches, we study plant-pathogen coevolution in wild ''Arabidopsis'' populations and how this is translated into the genetic composition of ''NB-LRR'' genes in local populations. This research is complemented by the study of the temperature effects on ''NB-LRR'' mediated defense triggering. <br><br>

Dear visitor,

Welcome to the webpage of the Molecular Genetics of Plant-Environment Interactions (Alcazar Lab) at the Department of Biology, Healthcare & Environment of the University of Barcelona.

We're a recently created 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.

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.
