A similar inversion was uncovered for other plants in a previously published data set for a different non-coding region of the chloroplast genome, suggesting that the inversional process may be a common feature of non-coding DNA evolution. Several implications for phylogenetic analysis are noted. Download to read the full article text

DNA inversions that may be relatively common features of chloroplast genome evolution (Kelchner and Wendel 1996; Graham and Olmstead 2000a). Inversions and tandem repeats can cause problems during alignment and subsequent phylo-genetic analysis. They can lead to erroneous nucleotide ho-mology assessment across the entire affected region and may

A chloroplast DNA inversion marks an ancient evolutionary split in the sunflower family. (Asteraceae). Proc. Natl. Acad.

Characterization. of a 50-kb Chloroplast DNA Inversion in the Flowering Plant Family Leguminosae 132 legume genera were screened for the presence of the inversion. The gene order in the SSC region of A. annua is inverted; this fact is consistent with the sequences of chloroplast genomes from three other Artemisia species. The gene order in ferns has been explained by a series of genomic inversions relative to the plastome organization of seed plants.

Detailed chloroplast DNA restriction site maps for two species in the genusAdonis (Ranunculaceae),A. annua andA. vernalis, were constructed using single and double digests and the sizes of these genomes are 151.3 and 156.5 kilobases, respectively. that chloroplast DNA within individual plants exhibits a form of heteroplasmy in which the plastome exists in two equimolar states (i.e., inversion isomers) that diff er in the relative orientation of the small single copy (SSC) region.

Putatively basal elements of the family have not been surveyed for the inversion, which is unknown outside the legumes. A 78 kb DNA inversion encompassing most of the large single copy region of the chloroplast genome marks a monophyletic group that comprises most genera in the subtribe Phaseolinae of the legume tribe Phaseoleae.

Robert Jansen. 2010-07-13 · Background The chloroplast trnH-psbA spacer region has been proposed as a prime candidate for use in DNA barcoding of plants because of its high substitution rate. However, frequent inversions associated with palindromic sequences within this region have been found in multiple lineages of Angiosperms and may complicate its use as a barcode, especially if they occur within species. Methodology What is the chloroplast DNA inversion What groups of plants have this feature from BIS 2C at University of California, Davis 2004-08-23 · Howe CJ: The endpoints of an inversion in wheat chloroplast DNA are associated with short repeated sequences containing homology to att-lambda.

We have determined the DNA sequences of regions involved in two of the three inversions known to have occurred during the evolution of wheat chloroplast DNA. This establishes the extent of the second largest of the three inversions.

Gene rearrangements in Chlamydomonas chloroplast DNAs are accounted for by inversions and by the expansion/contraction of the inverted repeat. Boudreau E (1), Turmel M.

The taxonomic distribution of the inversion is consistent with morphological and other data, and supports recent subtribal classifications. Chloroplast DNA inversions and the origin of the grass family (Poaceae) 1987-08-01 · Filter hybridizations using cloned chloroplast DNA restriction fragments of lettuce and petunia revealed that this 22-kilobase-pair inversion is shared by 57 genera, representing all tribes of the Asteraceae, but is absent from the subtribe Barnadesiinae of the tribe Mutisieae, as well as from all families allied to the Asteraceae. For example, examination of chloroplast DNA variation in the genus Clarkia proved useful in answering phylogenetic questions (Sytsma and Gottlieb, 1986). In the North American subsection Euoenothera of the genus Oenothera section Oenothera (see Stubbe and Raven, 1979) a gene rearrangement as compared to the spinach chloroplast DNA revealed a 45 kb inversion within the large single copy region Polymorphism for a 42-kb chloroplast DNA inversion was detected in five species of Abies and two species of Tsuga based on a sample of 1,281 individuals and both Southern hybridization and polymerase chain reaction (PCR) analyses.
