Hi all. I did not find any database containing data about positions of centromeres even in whole sequenced and annotated species (like oryza sativa, vitis viniferas, brachypodium and so on), so I would like to ask if there is any way how to locate those regions?
Thanks.

Please see my reply to one of the similar questions Michael indicates. While not talking about plants, that question and its replies will help you.

Thank you. Unfortunatelly I am interested only in plants, so it seems to be quite tough issue:)
The issues are the same whether it is a chimpanzee or grape centromere. Gene density changes (lower), SNP density changes, repeat content increases, low-complexity regions are more often noted. At the same time, precise coordinates of a centromere will be nearly impossible to obtain.
