The transcription factor GAGA, encoded by the gene Trl, controls expression of many Drosophila melanogaster genes. We have compiled the presently largest sample (120 sites) of published nucleotide sequences with experimentally confirmed binding to GAGA protein. Analysis of the sample has demonstrated that despite an apparent structural diversity of the GAGA(More)
The development of dorsal appendages of the chorion (specialized structures in the D. melanogaster egg which look like elastic tubes and ensure the breathing of the developing embryo) is an attractive model for the study of genetic mechanisms of the development of organs and tissues, whose generation is based on transformation of the epithelial tissue in(More)
Insects are surprising in the size and diversity of taxa, members of which are considered to be one of the best-adapted and most evolutionary successful living organisms. Insects are characterized by diversity and an abundance of adaptations to environmental conditions; the members of this class occupied different ecological niches, and it is possible to(More)
Multifunctional optogenetic systems are in high demand for use in basic and biomedical research. Near-infrared-light-inducible binding of bacterial phytochrome BphP1 to its natural PpsR2 partner is beneficial for simultaneous use with blue-light-activatable tools. However, applications of the BphP1-PpsR2 pair are limited by the large size, multidomain(More)
Phytochrome photoreceptors absorb far-red and near-infrared (NIR) light and regulate light responses in plants, fungi, and bacteria. Their multidomain structure and autocatalytic incorporation of linear tetrapyrrole chromophores make phytochromes attractive molecular templates for the development of light-sensing probes. A subclass of bacterial phytochromes(More)
