Basic scientific achievements

1. The study of the organization and genetic control of cellular signaling systems in higher plants revealed that: The enzymes of cyclic nucleotides (cAMP and cGMP), cyclases and phosphodiesterases strongly react to the influence of the monochromatic red (660 nm) and far-red (730 nm) light absorbed by phytochrome;

The nonhydrolyzable analogue of GTP  Gpp(NH)p influences the activity of cAMP exchange enzymes isolated from illuminated by red-lit etiolated maize and sorghum seedlings. At the same time, enzymes from un-illuminated seedlings do not react to the action of Gpp(NH)p.

2. The study of the role of GPR motif proteins in the exchange of guanine nucleotides using recombinant proteins revealed: All GPR (GoLoco) motif-containing proteins preferentially interact only with G-proteins Gαi class (Gαi1, Gαo, Gαt). GPR-motif proteins exhibit the same interaction pattern with Gαi1 in the following sequence of affinity: Gαi1GDP Gαi1GDPAlF4- Gαi1GTP S;

Upon binding to GiαGDP, GPR proteins compete with Gβγ. GPR proteins inhibit GDP dissociation, and with the inhibition of the GDP/GTP exchange, they can inhibit GPCR-activation of G proteins.

3. The study of molecular mechanisms for the transmission of extracellular signals using the rhodopsin receptor and the GPR protein transducin revealed the following features: Gαt interacts with C2, C3 and C4 intracellular loops. The residues of R147, F148 and to a lesser degree C140, K141 in the C2 loop, as well as the residues T229, V230, S240, and T242, T243, Q244 in the C3 loop participate in the interaction with Gαt. The juxtamembrane regions of loops are more important for R*/Gt binding than the regions in the central regions of the loops.

The residues N310, K311, F313, and M317 of the C4 loop are important for Gαt activation, while N310 and K311 are important for post-translational protein folding, and F313 and M317 for interaction with Gt.

4. As a transcriptional regulation of plant differentiation during development, the role of MADS domain transcription factor - JOINTLESS1 - in the formation of the abscission zone formation in flowers and leaves of tomato plants was studied.

Analysis of the signals obtained from the mutant and chimeric tomato plants shows that the programming and coordination of the differentiation of cells and tissues in the apical meristem occurs in the third (L3) layer, which coordinates cell division and in the first (L1) and second (L2) layers that differentiate the organs.

5. As transcriptional regulation of plant responses to abiotic stresses of the environment, the role of WRKY superfamily members in plant responses to abiotic stresses such as elevated salt and water deficiency has been studied. It was shown that the transcription factor of tomato plant WRKY33 is the main factor that regulates plant tolerance to abiotic stress, such as water deficiency and increased salinity.
