The Plant Development Genetics 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.
The Plant Development Genetics Group (DEVOLEG) 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. DEVOLEG group 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. Our goal is to identify 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 markers for genotypic selection.
Genomics of flowering time
Photoperiodic flowering 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 higher latitudes or altitudes, where grown under different photoperiods. So, flowering time is a key factor in this crop due to a change in allele frequencies of specific genes is found to enable latitudinal adaptation. Molecular characterization and hierarchical organization of the genes involved in flowering time will provide the knowledge about the genetic mechanisms involved in the common bean photoperiodic adaptation.
Conservation of genetic models in the domestication process
Photoperiod is known to affect other vegetative and reproductive traits in the common bean, such as the growth habit and branching. This variation is interesting from an agronomic point of view, and presents a challenge for matching flowering time to environment and planting time, and generally for improving common bean production in temperate regions. Once we understand the genetic mechanisms that regulate these characters, it is also possible to investigate the evolution of the same throughout the process of domestication in beans. 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.
