What's new in PGCI?

We’re excited to share our latest publication, "Sequencing-based characterization of the S-genotype of 56 Pyrus cultivars with identification of a novel S-allele", authored by Hanne Claessen!

This study investigates the precise S-genotypes of 56 pear varieties to solve ongoing challenges in orchard breeding and cultivation. By uncovering the genetic makeup of 24 previously uncharacterized cultivars and discovering a novel S129 allele, this research delivers a highly reliable genetic framework for maximizing fertilization success and fruit set.

Induction of unreduced gametes in banana (Musa spp.) to facilitate triploid breeding

 

Are you passionate about plant reproduction, crop breeding, and cutting-edge research?

 

We’re excited to share a fully funded PhD position at KU Leuven (Belgium) focused on inducing 2n pollen in banana (Musa spp.) to enable more efficient triploid breeding and unlock genetic variation in this key staple crop.

This multidisciplinary project integrates fundamental plant reproductive biology with applied crop improvement, offering a unique chance to contribute to both basic science and real-world solutions.

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.
