ATM and ATR make distinct contributions to chromosome end protection and the maintenance of telomeric DNA in Arabidopsis.

Genes & development - 15 Sept 2005

Vespa Laurent, Couvillion Mary, Spangler Elizabeth, Shippen Dorothy E

Abstract excerpt

Here we examine the function of ATM and ATR at telomeres in Arabidopsis. Although plants lacking ATM or ATR display wild-type telomere length homeostasis, chromosome end protection is compromised in atm atr mutants. Moreover, atm tert Arabidopsis experience an abrupt, early onset of genome instability, arguing that ATM is required for protection of short telomeres. ATR, by contrast, is required for maintenance of...
