摘要

The centromere is the most characteristic landmark of eukaryotic chromosomes. The centromere appears as a distinct primary constriction on condensed metaphase chromosomes. Centromeres are responsible for sister chromatid cohesion and are the sites for kinetochore assembly and spindle fiber attachment, thereby allowing for faithful segregation of sister chromatids during cell division. In the majority of eukaryotic species, centromeres are embedded within megabases of highly repetitive DNA which cannot be precisely sequenced. Determining the precise DNA boundary of a centromere has proven to be a difficult task. Rice provides an excellent model for centromere study because rice centromeres contain limited amount of repeats. This project aimed for an in-depth analysis of the structure, function, and evolution of rice centromeres.
