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.
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.

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 their microbiota? How plants maintain variability of genes involved in plant recognition and to which extent this variability is directly given by the interaction with pathogens? How the environment manipulates immune responses? To address these and other questions, we (and others) developed a new model for plant immunity studies based on the use of immune-related incompatible hybrids. These are hybrids obtained by crosses of natural Arabidopsis accessions that exhibit constitutive activation of defense, stunted growth and sterility. Often, such phenotypes are temperature-dependent and suppressed at high temperature. 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 Ler/Kas-2 incompatibility involves populations in Central Europe and Asia which enable to expand our analyses to population scales. We apply population genetics on top of molecular and biochemical analyses. Derived from our research we attempt to provide new fundamental strategies for crop protection. Observe, understand, improve and apply.
