My main interests are based on the application of modern genetic and bioinformatic techniques to the study of plant evolution. To do this I survey different species and natural populations of plants presenting variation in interesting characteristics, and analyze the responsible molecular mechanism. Here is an small description of some of my work: | |||

It is well known that plants from different light environments exhibit different degrees of responsiveness to similar light stimulus. Plants accommodated to sunny environments detect foliar shade from neighboring vegetation they respond increasing petiole and stem elongation and reducing the time to reproduction, a phenomenon called the "shade avoidance response". On the other hand, plants surrounded by tall vegetation are familiarized with the shade and do not present this response. | |||
To identify the molecular mechanisms underlying this differences we are performing QTL analysis using a previously developed, well characterized Recombinant Inbred Line set descent from two different natural populations of <i>Arabidopsis thaliana</i>: Bayreuth, originary from the German low altitude fallow lands, and Shahdara, from the high mountains of Tadjikistan <cite>Loudet02</cite>.<br> | To identify the molecular mechanisms underlying this differences we are performing QTL analysis using a previously developed, well characterized Recombinant Inbred Line set descent from two different natural populations of <i>Arabidopsis thaliana</i>: Bayreuth, originary from the German low altitude fallow lands, and Shahdara, from the high mountains of Tadjikistan <cite>Loudet02</cite>.<br> | ||
We grew replicated individual RILs in environments simulating shade and sun conditions and measured them for a number of traits characteristic of the shade avoidance response syndrome. For the QTL analysis we modeled this phenotipic data to calculate a shade avoidance response index and used an available genetic map that includes more than 500 Single Feature Polymorphism (SFP) markers <cite>West06</cite>.<br> | We grew replicated individual RILs in environments simulating shade and sun conditions and measured them for a number of traits characteristic of the shade avoidance response syndrome.
