The chloroplast DNA (cpDNA) inversion in the Asteraceae has been cited as a classic example of using genomic rearrangements for defining major lineages of plants. We further characterize cpDNA inversions in the Asteraceae using extensive sequence comparisons among 56 species, including representatives of all major clades of the family and related families.

Jansen The chloroplast DNA (cpDNA) inversion in the Asteraceae has been cited as a classic example of using genomic rearrangements for defining major lineages of plants. Unique inversion. The marama chloroplast genome appears to have a unique inversion, included in the LSC region, among the legumes. The inverted region is 7479 bp and includes the six genes rbcL, accD, psaI, ycf4, cemA, and petA.

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 Highlight The chloroplast genome of a basal legume has been assembled from next-generation sequence information.

Thompson 2,s 2020-05-14 · Comparative analysis of the four chloroplast genomes of L. chinense revealed 45 SNPs, 17 indels, 49 polymorphic SSR loci, and five small inversions. Most chloroplast intraspecific polymorphisms were located in the interspaces of single-copy regions. In total, 6147 SSR markers were isolated from low-coverage whole genome sequences. 12 chloroplast DNA mutations, including 11 nucleotide substitutions and one sequence inversion (Table2), and identiﬁed 21 haplotypes (haplotypes A to U) (Table2).

Two haplotypes were observed in all populations and species. We determined the distribution of a chloroplast DNA inversion among 80 species representing 16 tribes of the Asteraceae and 10 putatively related families.

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.

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.
