The various sections of IBBA deal with a plurality of biological material in study (animals, plants, mycorrhizas), but with a convergence on scientific themes (development of biosoftware; analysis of biodiversity; basic knowledge about regulation of gene expression, intracellular transport of proteins; physiological role of gene sequences; identification of control points for metabolic and signal transduction pathways; genetic analysis) with the use of common methodological approaches (isolation and characterization of gene sequences; site-specific mutagenesis; protein and metabolite analysis; microarrays, techniques of microscopy and cytogenetics; utilization of bioinformatic facilities; cell cultures).
