AbstractHigher plant DNA is extensively methylated, but the two methylated sequences (CpG and CpNpG) show different characteristics. Using sequence analysis techniques, we demonstrate that while CpG methylation follows the existing models for cytosine methylation in animals, CpNpG methylation does not.

Biology Bulletin Reviews, 2019
Abstract—The search for universal plant DNA barcodes has proved to be a big challenge. A single locus (or combination of several loci) that can be used for species identification has yet to be revealed, though the (rbcL + matK+ ITS) combination recommended in 2009 as the standard makes it possible to assign a species to the corresponding genus.

DNA and proteins of plant centromeres
Current Opinion in Plant Biology, 2003In plants, as in all eukaryotes, centromeres are chromatin domains that govern the transmission of nuclear chromosomes to the next generation of cells/individuals. The DNA composition and sequence organization of centromeres has recently been elucidated for a few plant species.

The extraction of DNA from plants is the starting point for genotype analysis. The approach to preparation of DNA from plants is determined by the species, the type of tissue or sample available and the analysis required on the DNA. For example, extraction of DNA from the leaf of a cereal for analysis using a robust test may require a very different ...

DNA in plants is highly methylated, containing 5-methylcytosine (m5C) and N6-methyladenine (m6A); m5C is located mainly in symmetrical CG and CNG sequences but it may occur also in other non-symmetrical contexts. m6A but not m5C was found in plant mitochondrial DNA. DNA methylation in plants is species-, tissue-, organelle- and age-specific.

Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1998
Numerous studies have demonstrated a requirement in plants for repair of DNA damage arising from either intrinsic or extrinsic sources. Investigations also have revealed a capacity for repair of certain types of DNA damage, and conversely, identified mutants apparently defective in such repair.

In Situ Analysis of DNA Methylation in Plants [PDF]
, 2010 Epigenetic regulation in the plant genome is associated with the determination of expression patterns of various genes. Methylation of DNA at cytosine residues is one of the mechanisms of epigenetic regulation and has been a subject of various studies. Various techniques have been developed to analyze DNA methylation, most of which involve isolation of

The Genomics of Plant Satellite DNA
2021The twenty-first century began with a certain indifference to the research of satellite DNA (satDNA). Neither genome sequencing projects were able to accurately encompass the study of satDNA nor classic methodologies were able to go further in undertaking a better comprehensive study of the whole set of satDNA sequences of a genome.

DNA Methylation and Demethylation in Plant Immunity
Annual Review of Phytopathology, 2016Detection of plant and animal pathogens triggers a massive transcriptional reprogramming, which is directed by chromatin-based processes, and ultimately results in antimicrobial immunity. Although the implication of histone modifications in orchestrating biotic stress–induced transcriptional reprogramming has been well characterized, very little was ...

DNA Assembly for Plant Biology
Current Protocols in Plant Biology, 2016AbstractParallel DNA assembly methods allow multiple fragments of DNA to be compiled in a desired order in a single reaction. Several methods enable the efficient one‐step assembly of multiple DNA parts into a suitable plasmid acceptor at high efficiency.
