Detailed introduction of the group
The group works on the topic of plant heat stress adaptation including both fundamental and applied research. 1 senior research fellow, 2 PhD students and 1 MSc student work in the group.
Short introduction of research topics
- Investigation of the roles of a conserved non-coding RNA-family in the fertilization of Angiosperms (NKFIH 137722);
Long non-coding RNAs (lncRNAs) were shown to be key players involved in different aspects of development. In spite of many lncRNAs being identified in plants, the potential roles for only a few lncRNAs have been brought to light.
In the present programme we aim to understand the roles of an lncRNA family. Preliminary results show that the lncRNA family is conserved in angiosperms, is expresed primarily in flower organs, is temperature regulated and the lncRNA mutants are male sterile. These suggest that these lncRNAs are involved in flower development, fertilization and temperature response during reproductive phase. The project will aim to in-depth charaterize the lncRNA transcription, decay, localization, cofactors and downstream actions. The work will be conducted on Arabidopsis thaliana, its close relative Brassica napus dicot crop. We hope that our findings will contribute to the understanding of the flower development and fertilization.
- Transcriptional and epigenetic regulation of heat stress response in Brassicaceae (NKFIHK129283).
Climate change negatively affects the yield of important crops all over the world. Rapeseed (Brassica napus) is an important agricultural crop. The valuable product of B. napus is the rapeseed oil, being now the third most important source of edible oil in the world. Rapeseed is sensitive to heat in all stages of its development. As research on crops is very laborious, the knowledge on rapeseed heat stress response is very limited.
In the present programme we propose to uncover the components of heat stress-specific PolII transcriptional complex and understand its regulation during heat stress response in a combined study on Brassica napus crop and Arabidopsis thaliana model. Specific aims of our project are (i) uncover central heat stress factor HSFA1 and A2 paralogs’ regulations and roles in B. napus, (ii) search and show biological relevance of heat stress-specific transcriptional complex co-factors in both A. thaliana and B. napus and (iii) uncover epigenetic regulators required for transcriptional changes driven by HSFs during heat stress.
We hope that our findings will contribute significantly to basic understanding of heat stress response and will accelerate the development of heat-tolerant plants that may have an immense significance in the light of climate change.
