Lead-induced DNA damage in Vicia faba root cells: Potential involvement of oxidative stress [PDF]

, 2011
Genotoxic effects of lead (0–20 µM) were investigated in whole-plant roots of Vicia faba L., grown hydroponically under controlled conditions. Lead-induced DNA damage in V.

Plant DNA Methylation Responds to Nutrient Stress

, 2022
Nutrient stress as abiotic stress has become one of the important factors restricting crop yield and quality. DNA methylation is an essential epigenetic modification that can effectively regulate genome stability.

Plant mitochondrial DNA

Frontiers in Bioscience, 2017
Plants possess mitochondrial genomes that are large and complex compared to animals. Nearly all animal mitochondrial genomes are about 16.5. kbp in length, whereas plant mitochondrial genomes range between 200-2,000 kbp. This is curious if we assume modern mitochondria originated from a common alpha-proteobacterial ancestor.

DNA associated with nucleosomes in plants [PDF]

Nucleic Acids Research, 1977
50 to 55% of tobacco and barley nuclear DNA is accessible to micrococcal endonuclease digestion. The DNA fragments resulting from a mild endonuclease treatment are multiples of a basic unit of 194 +/- 6 base pairs in tobacco and 195 +/- 6 base pairs in barley.

Plant-Derived Transfer DNAs [PDF]

Plant Physiology, 2005
Abstract The transfer of DNA from Agrobacterium to plant cell nuclei is initiated by a cleavage reaction within the 25-bp right border of Ti plasmids. In an effort to develop all-native DNA transformation vectors, 50 putative right border alternatives were identified in both plant expressed sequence tags and genomic DNA.

Influence of retinoblastoma-related gene silencing on the initiation of DNA replication by African cassava mosaic virus Rep in cells of mature leaves in Nicotiana benthamiana plants [PDF]

, 2011
Background Geminiviruses mainly infect terminally differentiated tissues and cells in plants. They need to reprogramme host cellular machinery for DNA replication.

Next generation systemic acquired resistance [PDF]

, 2011
Systemic acquired resistance (SAR) is a plant immune response to pathogen attack. Recent evidence suggests that plant immunity involves regulation by chromatin remodeling and DNA methylation.

A DNA barcode for land plants [PDF]

Proceedings of the National Academy of Sciences, 2009
DNA barcoding involves sequencing a standard region of DNA as a tool for species identification. However, there has been no agreement on which region(s) should be used for barcoding land plants. To provide a community recommendation on a standard plant barcode, we have compared the performance of 7 leading candidate plastid DNA regions (
