DNA Damage in Plant Herbarium Tissue
Dried plant herbarium specimens are potentially a valuable source of DNA. Efforts to obtain genetic information from this source are often hindered by an inability to obtain amplifiable DNA as herbarium DNA is typically highly degraded. DNA post-mortem damage may not only reduce the number of amplifiable template molecules, but may also lead to the generation of erroneous sequence information. ...
متن کاملTemporal patterns of damage and decay kinetics of DNA retrieved from plant herbarium specimens
Herbaria archive a record of changes of worldwide plant biodiversity harbouring millions of specimens that contain DNA suitable for genome sequencing. To profit from this resource, it is fundamental to understand in detail the process of DNA degradation in herbarium specimens. We investigated patterns of DNA fragmentation and nucleotide misincorporation by analysing 86 herbarium samples spannin...

Spring summer 2010, Vol.4, No.1 /74 Medical Laboratory Journal Severity of Oxidative DNA Damage in Gastric Tissue of Smoker and Non-smoker Patients with Dyspepsia Abstract Background and Objectives: Cigarette smoking is associated with an increase in risk of peptic ulcer and Gastro-Intestinal cancer. Toxic materials in smoke and tar have a significant role in production of carcinogenic complexe...
متن کاملUpdate on DNA Damage Repair DNA Damage Repair in the Context of Plant Chromatin
The integrity of DNA molecules is constantly challenged. All organisms have developed mechanisms to detect and repair multiple types of DNA lesions. The basic principles of DNA damage repair (DDR) in prokaryotes and unicellular and multicellular eukaryotes are similar, but the association of DNA with nucleosomes in eukaryotic chromatin requires mechanisms that allow access of repair enzymes to ...
متن کاملHypersensitivity to DNA damage in plant stem cell niches.
The growing apices of plants contain stem cells that continually produce tissues, which, in the shoot, include the germline. These stem cell populations remain active throughout the plant's life, which can last for centuries, and are particularly exposed to environmental hazards that cause DNA damage and mutations. It is not known whether plants have mechanisms to safeguard the genome specifica...
