Plants, like all known organisms, use DNA to pass on their traits. Animal genetics often focuses on parentage and lineage, but this can sometimes be difficult in plant genetics due to the fact that plants can, unlike most animals, be self-fertile.
The genes of most plant and some animal (e.g., insects and fish) species carry transposons, which are short, naturally occurring pieces of DNA with the ability to move from one location to another in the genome.
A molecular or DNA marker is the difference in DNA nucleotide sequence—between individual organisms or species—that is in proximity or tightly linked to a target gene that expresses a trait.
20 lut 2024 · In this section, we describe three applications of pangenomes in crop plant genetics: mapping or selecting for beneficial alleles, the generation of inventories of resistance genes (also known...
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.
10 paź 2008 · We identified the unique genes within both A. thaliana and O. sativa genomes and classified them according to the number of homologs in the alternative species: none (U {1:0}), one (U {1:1}) or several (U {1:m}).
19 paź 2020 · Here, we describe how plant genomes have been harnessed for studies of plant phylogeny and diversification, with examples spanning all green plants, a clade of nearly half a million species spanning nearly a billion years of evolutionary time.
