The Brassica genus encompasses three diploid and three allopolyploid genomes, but a clear
understanding of the evolution of agriculturally important traits via polyploidy is lacking. We …

For >20 years, the enigmatic behavior of plant mitochondrial genomes has been well
described but not well understood. Chimeric genes appear, and occasionally are differentially …

The plant mitochondrial genome is retained in a multipartite structure that arises by a process
of repeat-mediated homologous recombination. Low-frequency ectopic recombination also …

Background The mitochondrial genome of higher plants is unusually dynamic, with
recombination and nonhomologous end-joining (NHEJ) activities producing variability in size and …

The plant mitochondrial genome is characterized by a complex, multipartite structure. In
cytoplasmic male-sterile (CMS) common bean, the sterility-inducing mitochondrial configuration …

The plant mitochondrial genome is recombinogenic, with DNA exchange activity controlled
to a large extent by nuclear gene products. One nuclear gene, MSH1, appears to participate …

Stability of the mitochondrial genome is controlled by nuclear loci. In plants, nuclear genes
suppress mitochondrial DNA rearrangements during development. One nuclear gene …

Mitochondrial-plastid interdependence within the plant cell is presumed to be essential, but
measurable demonstration of this intimate interaction is difficult. At the level of cellular …

The processes accompanying endosymbiosis have led to a complex network of interorganellar
protein traffic that originates from nuclear genes encoding mitochondrial and plastid …

Plant phenotypes respond to environmental change, an adaptive capacity that is at least
partly transgenerational. However, epigenetic components of this interplay are difficult to …
