Ginkgo biloba vascular cambium mitochondrial damage related chromosome outer circular DNA, and screening method and application thereof

The invention provides chromosome outer circular DNA related to gingko vascular cambium mitochondrial damage and a screening method and application thereof, and relates to the technical field of biology. The invention provides chromosome outer circular DNA related to mitochondrial damage of ginkgo vascular cambium. The chromosome outer circular DNA is obtained by detecting and identifying healthy ginkgo vascular cambium under mitochondrial damage. Experiments prove that the [TAR1circle] is highly related to the mitochondrial retrograde signal transduction of the ginkgo vascular cambium, and through the research on the eccDNA, the molecular mechanism of the eccDNA participating in the plant mitochondrial retrograde signal transduction can be further disclosed, and an eccDNA reference standard is provided for potential biomarkers of plants responding to mitochondrial damage. 本发明提供了一种银杏维管形成层线粒体损伤相关的染色体外环状DNA及其筛选方法和应用，涉及生物技术领域。本发明提供了一种银杏维管形成层线粒体损伤相关的染色体外环状DNA，通过对健康和线粒体损伤下的银杏树木维管形成层进行检测与鉴定所得。经试验证实可知，本发明所述的[TAR1cir
