We invite you to listen to Prof. Paweł Chmielarz’s lecture entitled “Forest in the freezer or in a test tube?”
Genetic resources are usually stored as desiccated seeds, at negative temperatures in gene banks. But what if the seeds are intolerant to desiccation or the plants fail to develop seeds? Then one preserves small tissue fragments in liquid nitrogen that, after defrosting, can be used to cultivate complete plants via in vitro cultures. Can dying old oak trees be cloned 'in glass' to preserve their gene pool? A prerequisite for the success of any method is to understand the biology of the seeds and to recognise the potential for micro-propagation of species.

We invite you to listen to Dr. Błażej Wójkiewicz’s lecture entitled “Genetic variability and adaptive potential of forest tree populations”.
Rapidly advancing climate change is responsible for intensifying stressful stimuli in the natural environment. Forest trees that fail to adapt to the new environmental conditions will perish under progressive natural selection. The genetic diversity of the individuals that make up a population of trees of a particular species will be a major determinant of whether or not it survives in a particular area. Monitoring and preserving the genetic resources of forest tree populations can be critical to their survival in their current habitats.

We invite you to listen to Prof. Witold Wachowiak’s lecture entitled “Understanding the hard drive of pines”.
Understanding the genetic basics of how organisms function, including access to the information encoded in the genome, which acts as their molecular hard drive, is essential in predicting the response of living organisms to environmental changes and in making decisions in favour of the preservation of populations and species under changing environmental conditions. Our research on Scots pine is dedicated to these issues.

We invite you to listen to Dr. Ewelina A. Klupczyńska’s lecture entitled “Do plants have memory and can it be erased?”
Higher plants have complex mechanisms that enable them to respond to environmental changes. These reactions are controlled at the molecular level by epigenetic modifications and variations in gene expression. Due to epigenetic memory and epigenome changes, through chromatin modifications in environmentally responsive genes, plants are able to remember past experiences, which allows them to adapt to changing climatic conditions, also linked to global climate change.

We invite you to listen to Dr. Weronika B. Żukowska’s lecture entitled “Significance and conservation of genetic diversity”.
Genetic diversity is of great importance in light of ongoing climate changes. It is essential for the proper functioning of populations and species in changing environmental conditions. Livestock and crops like grains and vegetables, as well as fruit trees and shrubs, are particularly vulnerable to genetic diversity loss. However, we can all contribute to the protection of genetic diversity.
