Development of novel gibberellin derivatives to control sex identity and fruit development in tomato stamenless mutant – Markéta Fuksová

Markéta Fuksová is currently a Ph.D. student of Palacký University in Olomouc. While working on her project (lasting from March 2020 to September 2022), she cooperated with the Laboratory of Growth Regulators of IEB. Her project was focused on the preparation of new compounds derived from plant hormones gibberellines (that are crucial e.g. for the fruit development) and understanding the effects of gibberellines in stamenless tomato mutants. Her work was supported with 42,485 CZK.

Thanks to the financial support, Markéta could do an internship at the renowned Catholic University of Louvain, Belgium in the spring of 2022. Until then, her research was focused mainly on the chemical synthesis and preparation of gibberellines. The internship allowed her to examine these compounds and their effects on the plant in practice.

She discovered that two particular gibberellines could partly restore the formation of stamens in those tomato mutants. In addition, she tested a newly synthetized substance from the group of antigibberellines (substances with the opposite effect than gibberellines) and discovered it had even stronger effect than an antigibberelline traditionally used in growing crops and ornamental plants. This new antigibberelline therefore seems to be promising but deserves further research.

Evaluation of anti-inflammatory and anticancer activity in selected fern species – Antonio Pavičić

Antonio Pavičić is a Ph.D. student of Charles University. His project, lasting from March 2020 until February 2022, was aimed at discovering medicinally applicable substances with anti-inflammatory, anti-cancer and anti-parasitic effects in European fern species. The main goals were to discover such compounds in extracts from selected fern species and test their potential.

The means (100,000 CZK) received from the Fund covered the costs of his research (including an internship at the University of Pretoria in South Africa) and were also used to fund his attendance and poster presentation at an international conference in Varna, Bulgaria.

Antonio Pavičić discovered anti-inflammatory compounds in a few out of 16 species examined, with Dryopteris aemula seeming to be the most promising species for further research. Furthermore, extracts from some species proved toxic for cancerous cells. These extracts thus could have a lot of potential as the colorectal cancer is one of the most common causes of death from cancer. In addition, some extracts had antibacterial effect. His results suggest that European ferns could be medicinally useful but further research will be needed.

 

Markéta’s and Antonio’s projects not only contributed to expanding our state of knowledge in these fields of plant experimental biology but also helped them to broaden their experience, skills and networking and to grow scientifically and personally.
