Plant Cell Biology and Biotechnology

Offer

We offer our expertise related to molecular and cellular biology of plants and plant cell lines:


- Analyzing and discovering basic functions of plant genes

- Characterizing of genes and proteins potentially important in agriculture, horticulture and industry

- Introducing genes to produce genetically modifi ed plants with desirable phenotype

- Inducing RNA interference for silencing of selected genes

- Knock-outing of selected genes by CRISPR-Cas9

- Utilizing plant cell lines for various basic research and biotechnological purposes

- Breeding of carnivorous plants

Know-how & Technologies

Plant cell biology and biotechnology is a fascinating research field focusing on basic functions of plant cells with the potential of connecting the high-quality fundamental research with many different applications in agriculture, horticulture and biotechnology. We study:


- Cytoskeleton at the molecular and cellular level and its role in plant morphogenesis and signalling

- Mechanism of auxin transport and the role of cytoskeleton in auxin-directed plant development

- Mechanisms of RNA interference – (trans)gene silencing at transcriptional and posttranscriptional level

- Photosynthesis and nitrogen assimilation (role of PsbO and GS2 proteins)

- Molecular interactions of plant cells with pathogens (fungus Venturia inequalis causing apple scab disease)

Research Area & Excellence

Our research focuses on several topics extending the knowledge of molecular functioning of selected molecular components involved in cellular processes and intra- and intercellular signalling ranging from cytoskeleton and its role in morphogenesis of the cells, RNA interference (mechanisms of gene silencing) and

photosynthesis to auxin transport mechanisms and molecular responses to pathogens.

Key Research Equipment

State of art methods of molecular biology and biochemistry:

- DNA and RNA isolation, PCR, RT-PCR, DNA or RNA hybridization, methods of genetic manipulation: plant cells and tissues transformation via electroporation, biolistics or Agrobacterium mediated, native or recombinant plant proteins production in bacteria, profi ling of mRNA and small RNA with RNAseq

- Proteomic approaches: (recombinant) protein isolation, SDS PAGE, blue native PAGE, 2D PAGE, mass spectrometry, studies on protein interactions in vitro

- Immunodetection of proteins (e.g. western blotting, immu no staining)

- In silico analysis: NGS data-mining, database screening, phylogenetic analysis

- Routine usage of facilities providing advanced methods of optical and electron microscopy (fluorescence confocal microscopy and super-resolution microscopy, including SIM, TIRF/VAEM, FLIM, FRAP, FRET, SEM, ESEM and TEM, flow cytometry

- Methods mentioned above are applied on our model organisms, such as Arabidopsis thaliana, Nicotiana tabacum (BY-2 and

VBI-0 lines), Malus domestica, Solanum tuberosum, green algae (Chlorella, Chara, Klebsormidium, Closterium etc.) and yellow-green microalgae (Vischeria, Nannochloropsis).
