RESEARCH TOPICS
1. Microspore embryogenesis and doubled haploids (DH).
(i) Identification of (epi)genetic, proteomic and hormonal factors determining the effective reprograming of microspore developmental pathway in various cereal (triticale, wheat, barley, rye) and industrial crop species, including oilseeds (oilseed rape).
(ii) The role of reactive oxygen species and oxidoreductive balance in the induction and regulation of microspore embryogenesis in triticale, rye and barley.
(iii) Identification of ‘cell death’ programme (PCD) elements as factors modifying the efficiency of microspore embryogenesis in triticale and rye.
(iv) Optimisation of DH lines production methods of cereal, grass and oilseed rape plants using anther and isolated microspore cultures.
2. Drought as a factor modifying molecular background, cellular metabolism and initiating specific plant defence mechanisms.
(i) Effects of soil drought on the chloroplast proteome and activity of selected proteins in winter barley.
3. Mechanisms controlling seed development in barley.
(i) Analysis of the organisation and modification of chromatin structure in embryo and endosperm cell nuclei in developing seeds.
(ii) Identification and characterisation of imprinted genes determining endosperm development.
4. Involvement of secondary metabolism in the control of plant growth and development and in defence responses to environmental stress (in collaboration with Malopolska Centre of Biotechnology and Małopolska Hodowla Roślin Sp. z o.o.).
(i) Modification of the profile of secondary metabolites to enhance the defence mechanisms of crops, improve yields and use as a source of valuable compounds for industry, including pharmaceuticals.
(ii) The role of hormones in the regulation of defence mechanisms and activation of metabolic pathways related to plant resistance. Research on the role of the enzyme myrosinase in the activation of glucosinolates and their importance in the plant defence system against herbivores and pathogens.
