About the meeting

Meiosis is at the center of sexual reproduction. It ensures the creation of a new variation by mixing genetic material from the parents. In plants, this plays a key role not only in the context of natural selection and evolution, but also breeding for food security.

PMM will provide a platform for discussing topics related to the latest discoveries in plant meiosis, with a special focus on the control of meiosis and mechanisms of recombination. Population and evolutionary aspects of plant meiosis will also be covered. Furthermore, we will have the opportunity to see the latest discoveries and progress in plant breeding strategies.

An essential aspect of the meeting is to create a friendly atmosphere that will stimulate the exchange of knowledge and ideas between scientists and specialists. This is a unique opportunity to establish collaborations on future projects. The meeting will also serve as a platform for academic exchange between young, aspiring scientists and experienced, recognized researchers in the field of plant genetics.
