What's new in PGCI?
We’re excited to share our latest publication, "Gibberellin Treatment Impacts Fruit Shape in the Pyrus Communis Cultivar “Conference” Through Increased Retention of Apical Fruit", authored by Hanne Claessen and Han Palmers.
This study investigates the long-suspected link between gibberellin treatments and fruit deformation in the widely cultivated Pyrus communis cultivar “Conference.” These pears are often prone to developing an undesirable “bottle-shaped” appearance, leading to reduced market value and economic losses. By analyzing the effects of gibberellin treatments across two cultivars—“Conference” and “Doyenné du Comice”—and considering flower position within the cluster, the study reveals that gibberellins do not directly deform the fruit. Instead, the treatments promote retention of apical flowers, which naturally produce more elongated fruit, thereby increasing the proportion of misshapen pears.

The PGCI Lab is delighted to announce that Han Palmers and German Vighi have successfully defended their PhD theses. These accomplishments are the result of years of dedication, hard work, and outstanding research conducted at the PGCI Lab. Congratulations to both!
We extend our heartfelt congratulations to them and sincerely thank them for their valuable contributions to the research efforts of our lab. We are also grateful to the advisors, committee members, and collaborating organizations whose support was instrumental throughout this journey.
The PGCI Lab is thrilled to announce the PhD graduation of Aybars Koç, who has successfully defended his thesis titled "Mechanistic Insights into Meiotic Restitution Under Stress Conditions in Arabidopsis thaliana"!
We are proud to welcome him as Dr. Aybars Koç! Even more exciting, Aybars will be continuing his journey with us as a postdoctoral researcher, where he’ll further advance his work and help grow our collective expertise.
Big congratulations to Lucas Philips and Jarne Sels of PGCI, for obtaining Research Foundation Flanders (FWO) grants for their PhD projects!
In the next 4 years, Jarne will aim to uncover new insights into the molecular regulation of the progression of meiosis, that ensures genetic diversity and proper plant reproduction. Understanding meiosis at a deeper level could provide key information not just for plant biology, but for broader applications in genetics and agriculture.
As one of Europe's leading pear producers, Flanders faces many ongoing challenges in pear cultivation. By understanding the underlying mechanisms of meiotic recombination, Lucas will aim to develop tools for improving pear varieties and addressing these local and global challenges.

Our mission statement
One of the main scientific challenges in the coming years will be to guarantee a stable food supply in the face of climate change, environmental degradation and an increasing world population. Key to meeting these challenges is the development of new, stress resistant crop varieties for sustainable growth and production.
Therefore, our mission at PGCI is to conduct excellent research in plant sciences for the improvement of fruit production and quality, to protect the environment, and to benefit consumer health.
PGCI works primarily with apple, pear banana and model plant Arabidopsis, applying cutting edge knowledge and technologies to gain understanding into the control of biological processes necessary for modern and efficient fruit breeding and selection programs. We also provide training in the biosciences, actively follow opportunities for knowledge transfer and innovation to industry, and aim to engage the public and other interested stakeholders in dialogue on issues of scientific interest.
