Research Interests:


We are interested in systems analysis of the mechanisms of development in Drosophila and closely related insects. There are two related directions: (i) sequence analysis of transcription regulatory regions and (ii) quantitative modeling of spatio-temporal gene networks in Drosophila.

Major object is a group of early developmental genes, activated before gastrulation and involved into specification of germ layers (mesoderm, ectoderm etc) and presumptive segments. Formally, one can subdivide early developmental genes into two groups comprising Anterior-Posterior (AP) and Dorso-Ventral (DV) gene networks. Genes in the AP domain (gap and pair-rule) play central role in the embryo segmentation; genes in the DV domain (Dorsal target genes) are essential to specification of germ layers and cell types. Both AP and DV genes receive instructions from maternal determinants (such as transcription factors Bicoid or Dorsal), passed through the gene control regions enhancers or cis-regulatory modules (CRMs). Often, enhancers occupy large portions of the gene loci, so they contain substantial amount of discrete sequence information. In response to the maternal instructions, the discrete sequence information unfolds into the continuous information of spatial gene expression patterns (stripes), specifying future body parts.

Exact mechanisms of the enhancer response to the maternal instructions are not clear; little is known about integration of inputs from multiple enhancers at the level of gene; reasons behind robustness of large developmental gene networks are even more obscure.
