Genetics of Plant-Environment Interactions

Dear visitor,

Welcome to the webpage of the Alcázar Lab at the University of Barcelona.We study the genetic and molecular bases for the adaptation of plants to their local environments. We focus on the evolutionary adaptation of plant populations to abiotic and biotic stresses, which are major challenges for plant survival. Derived from our basic 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.


1. Natural variation and evolution of immune resistance genes in plants.

Plant resistance to pathogens is an important field of research with direct applications and we study it from an evolutionary, population genetics and molecular view. We currently study the molecular bases and evolution of Resistance genes and other loci that condition immune activation. We do so by studying Arabidopsis natural hybrids that exhibit activation of defense and fitness loss. We explore the mechanisms that have naturally evolved in plant populations to resist against pathogens and how the immune receptor repertoire is selected and diversified. At the direct interface between plants and the environment, we study how temperature modulates some plant immune responses.

2. Natural variation of abiotic stress tolerance and adaptation

We investigate the molecular and genetic mechanisms underlying the naturally occurring tolerance to abiotic stresses in plant populations. We're currently studying the genetic bases for the naturally occurring variation of stress protective metabolites that condition resistance in plants.
