Control of chromatin fates in pollen

Research focus

Constitutive heterochromatin is involved in multiple chromosomal processes including silencing of repetitive DNA and chromosome segregation. We have found global centromeric heterochromatin decondensation in Arabidopsis pollen, which evokes a new aspect of constitutive heterochromatin. We aim to isolate genes involved in this process.
