    The role of ATM in chromosome end protection in Arabidopsis thaliana

  • Original language description

    ATM has an essential role in the DNA damage response. However, it is still unclear if ATM has a direct protective function specifically at telomeres. We addressed this question by FISH. We show that although chromosome fusions are induced by critically short telomeres, most of the anaphase bridges contain no telomeric of subtelomeric DNA signals, which strongly suggests that ATM protects short telomeres against an exonucleolytic attack.

    Úloha ATM v ochraně konců chromozómů u Arabidopsis thaliana

  • Czech description

    Ataxia telangiectasia mutated (ATM) hraje důležitou úlohu v odpovědi na poškození DNA. Je rovněž aktivní při údržbě telomer. Abychom zjistili, zda se ATM přímo účastní ochrany telomer, použili jsme FISH techniku pro mapování konců chromozómů mutantních rostlin (atm) Arabidopsis. Identifikovali jsme chromozómové fúze vzniklé následkem deprotekce telomer, což indikuje, že ATM chrání telomery před atakem exonukleáz.
