Transposable elements (TEs), also known as "jumping genes" or transposons, are sequences of DNA that move (or jump) from one location in the genome to another.
The DNA segments that carry this genetic information are called genes, and their location within the genome are referred to as genetic loci, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
20 gru 2005 · While horizontal genetic transfer occurs most commonly in bacteria, it has been detected in animals as well. Most transfers between higher animals involve the movement of transposons. Horizontal transfer can also occur between the mitochondrial DNA of different plant species.
2 lut 2021 · This review discusses the features of cis-regulatory sequences in plants, technologies enabling their identification, characterization, and validation, their organization into functional cis-regulatory modules, their genomic distributions with respect to target genes, and the role of transposable elements in their evolution.
1 sty 2010 · Horizontal gene transfer (HGT) is increasingly being recognized as a significant force in the evolution of eukaryotic genomes. Plants have been both donors and recipients of horizontally mobilized genes and their genetic barter partners include prokaryotes and eukaryotes from all kingdoms.
30 sie 2023 · Martienssen and Joshua-Tor have now shown how protein DDM1 makes way for the enzyme that places these marks on new DNA strands. Plant cells need DDM1 because their DNA is tightly packaged. To keep their genomes compact and orderly, cells wrap their DNA around packing proteins called histones.
30 kwi 2018 · Nature Plants - This Review highlights current understanding of how polyploidization affects plant genome evolution by focusing on the post-polyploidization events, including gene retention...
