Impact of repetitive sequences on structure, evolution and function of plant centromeres (GAP501/11/1843)

Centromere is one of the most important chromosome domains as it is essential of centromere is conserved in all eukaryotes, underlying DNA is surprisingly variable between species and its role in centromere determination an...

A pangenomic view of expanding centromere (GA24-10036S)

Centromeres are essential chromosomal regions that facilitate proper, centromeres exhibit high variation in size, structure, and sequence composition. However, compromising our understanding of the general principles of centrome...

Utilizing new models and technologies to elucidate centromere determination in plants (GA17-09750S)

Centromeres are chromosomal structures which are essential for the proper for hereditary processes, the principles of centromere determination are only poorly understood. This is mainly due to the lack of knowledge about centrom...

Evolutionary new centromeres in plants (GA23-06840S)

Centromeres are required for regular segregation of monocentric chromosomes. Centromere repositioning (CR) and evolutionary new centromeres (ENCs) refer to the formation of a centromere at a different position on t...

Evolution of genome size - a new role for the centromere drive (GA20-15989S)

Maintaining the size ratio of chromosomes (“luggage”) and their kinetochores (“handles”) should mean that the kinetochore size divergence caused by centromere drive the drive is absent. This so far unrecognized effect of centromere ...

Changes in kinetochore composition and structure associated with holocentric chromosome formation (GA20-25440S)

The centromere and kinetochore are essential for proper chromosome segregation, therefore, understanding the principles of their organization, structure and function is of great importance. Most research into centromeres and kinetoc...

Evolution of holocentric chromosomes (GA13-29362S)

An adaptive origin of holocentric chromosomes (without localized centromere) as a defense against centromere drive will be analyzed using selection regimes acting on kinetochore proteins. To explain surprisingly negative 2C/2n corre...
