Chromoanagenesis in the <i>asy1</i> meiotic mutant of <i>Arabidopsis</i>

Abstract

Abstract Chromoanagenesis is a catastrophic event that involves localized chromosomal shattering and reorganization. In this study, we report a case of chromoanagenesis resulting from defective meiosis in the MEIOTIC ASYNAPTIC MUTANT 1 (asy1Arabidopsis thalianaasy1- Plain Language SummaryChromoanagenesis is a complex and catastrophic event that results in severely restructured chromosomes. It has been identified in cancer cells and in some plant samples, after specific triggering events. Here, we identified this kind of genome restructuring in a mutant that exhibits defective meiosis in the model plant system Arabidopsis thaliana
