DNA damage in plant herbarium tissue. [PDF]
PLoS ONE, 2011 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.

International Journal of Molecular Sciences, 2019 Maintenance of genome integrity is a key process in all organisms. DNA polymerases (Pols) are central players in this process as they are in charge of the faithful reproduction of the genetic information, as well as of DNA repair. Interestingly, all eukaryotes possess a large repertoire of polymerases.

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.

Targeted DNA insertion in plants [PDF]
Proceedings of the National Academy of Sciences, 2021 Conventional methods of DNA sequence insertion into plants, usingAgrobacterium-mediated transformation or microprojectile bombardment, result in the integration of the DNA at random sites in the genome. These plants may exhibit altered agronomic traits as a consequence of disruption or silencing of genes that serve a critical function.

DNA From Plant Mitochondria [PDF]
Plant Physiology, 1966 DNA WAS ISOLATED FROM A MITOCHONDRIAL FRACTION OF EACH OF THE FOLLOWING PLANT MATERIALS: Mung bean (Phaseolus aureus) etiolated hypocotyl; turnip (Brassica rapa) root; sweet potato (Ipomoea batatas) root; and onion (Allium cepa) bulb. It was found that all of these mitochondrial fractions contained DNA, the densities of which were identical (rho=1.706 ...

Active DNA Demethylation in Plants [PDF]
International Journal of Molecular Sciences, 2019 Methylation of cytosine (5-meC) is a critical epigenetic modification in many eukaryotes, and genomic DNA methylation landscapes are dynamically regulated by opposed methylation and demethylation processes. Plants are unique in possessing a mechanism for active DNA demethylation involving DNA glycosylases that excise 5-meC and initiate its replacement ...

Regulating DNA Replication in Plants [PDF]
Cold Spring Harbor Perspectives in Biology, 2012 Chromosomal DNA replication in plants has requirements and constraints similar to those in other eukaryotes. However, some aspects are plant-specific. Studies of DNA replication control in plants, which have unique developmental strategies, can offer unparalleled opportunities of comparing regulatory processes with yeast and, particularly, metazoa to ...

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 Methylation Readers in Plants
Journal of Molecular Biology, 2020 In plants, DNA methylation occurs in distinct sequence contexts, including CG, CHG, and CHH. Thus, plants have developed a surprisingly diverse set of DNA methylation readers to cope with an extended repertoire of methylated sites. The Arabidopsis genome contains twelve Methyl-Binding Domain proteins (MBD), and nine SET and RING finger-associated (SRA)
