He teaches general biochemistry and plant biochemistry courses. His research covers areas of biochemistry, cell biology, genetics and genomics of plants, with special interests in cell wall biosynthesis, flower and seed development, and biological nitrogen fixation.
Cellulose synthesising complex consists of cellulose synthase (CESA) subunits encoded by a multigene family; different sets of genes are known to be expressed during primary and secondary cell wall formation. We examined the expression of in flax ( L.) cellulosic fibres at various stages of development and in the course of graviresponse by means of RNA-Seq and quantitative PCR. Transcripts for both primary and secondary cell wall-related were abundant in fibres depositing highly cellulosic tertiary cell walls. Gravistimulation of flax plants temporally increased the abundance of transcripts, specifically in phloem fibres located at the pulling stem side. Construction of coexpression networks for revealed that both primary and secondary cell wall-related were involved in the joint coexpression group in fibres depositing tertiary cell walls, as distinct from other tissues, where these genes were within separate groups. The obtained data suggest that fibres depositing tertiary cell walls have a specific mechanism of cellulose biosynthesis and a specific way of its regulation.

Plant fibres with a tertiary cell wall (G-layer) may function as plant ‘muscles’. Large-scale transcriptome profiling of isolated flax phloem fibres permitted to identify the major players and regulatory elements that operate during graviresponce specifically in the fibres of the pulling stem side. The suggested mechanisms of phloem fibre involvement in tropisms may considerably renew the concept of herbaceous plant behaviour upon gravistimulation.
