Postdoctoral Research Fellow - Genetic Recombination for Advanced Crop Breeding
Are you passionate about plant genetics, meiosis, and cutting-edge crop breeding innovation? The Laboratory for Plant Genetics and Crop Improvement (PGCI) at KU Leuven is looking for a Postdoctoral Researcher to join our ambitious MeioCOntrol project.
This FWO-SBO funded initiative unites KU Leuven, ILVO, and UGent in unraveling the key determinants of meiotic recombination in maize, soybean, and tomato — with the goal of boosting genetic diversity and breeding efficiency.
We’re seeking a postdoctoral researcher with a PhD in plant genetics or related fields, strong expertise in CRISPR, genomics, and bioinformatics, and proven coordination skills to lead cross-institutional research, supervise PhD projects on key crops, apply advanced molecular techniques, and engage with industry partners—ideally with additional experience in meiotic cytology, microscopy, or breeding industry collaboration.

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.

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.
