BAS is a research group at the Misión Biológica de Galicia, an institute belonging to the Spanish National Research Council - CSIC, founded in 1921 and located in Pontevedra, Spain.
BAS focus on the study of the genetic mechanisms of plant development, differentiation and growth, at the molecular, physiological and genetic level. The gene regulatory networks needed to build a specific organ or tissue, to define the plant architecture, fruit development and floral transition, and to make the plant an organism well adapted to the environmental conditions. BAS develops its studies using common bean as a model crop.
Genetics of fruit development
The agronomic importance of the fruit of common bean lie in its use as a dry legume as its most recent use as fresh or processed vegetable. Fruit development has been a key factor in the evolution of the crop, especially as dry pod, since domestication has selected favorable genetic combinations for seed protection and control of the seed spread. Quantitative Trait Loci or QTLs involved in pod development were identifed in previous studied. Our goal is wether major regulatory genes of fruit development are conserved in this model legume, which allow not only to know the function of these genes during the formation of the fruit, but include them as the best markers for genotypic selection of elite lines.
Model of the photoperiod pathway
Photoperiodic response and adaptation has been a key factor in the evolution of common bean crop. Wild types only flower under short-days, suffering a strong selection process during the dissemination to other continents, where grown under different photoperiods. So, flowering time is a key factor in this crop due to the involvement of this trait in the adaptation to different latitudes. Short- and long-day specific QTLs were detected in our works. Molecular characterization and hierarchical organization of the genes involved in flowering time will provide the genetic mechanisms involved in common bean.
Conservation of genetic models in the domestication process
Once we understand the genetic mechanisms that regulate these characters, it is also possible to investiagte the evolution of the same throughout the process of domestication. The identification of the exact structure and genes that control not only allow to decipher the genetic mechanisms underlying the fixing domesticated trait but also provide information on the evolution of these widely existing in nature complex morphological features. Our goal is analyze the presence of polymorphism in the nucleotide sequence of coding an regulatory regions of the above-characterized genes, as well as differences in the expression patterns of these genes, and their correlation with contrasting phenotypes.
