Chloroplast DNA inversion polymorphism in populations of Abies and Tsuga. 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. Two haplotypes were observed in all

The gene order in ferns has been explained by a series of genomic inversions relative to the plastome organization of seed plants. Here, we examine for the first 13 Jul 2010 Background The chloroplast trnH-psbA spacer region has been proposed as a prime candidate for use in DNA barcoding of plants because of 20 Mar 2008 Close analysis of the ancestral genome structure suggests that genome rearrangement in chloroplasts is probably limited by inverted repeats with the corn chloroplast genome a large inversion of. -50 kb relative to the genomes of three legumes- mung bean, pea and broad bean. There is one additional. 27 Jan 2021 The chloroplast genome (plastome) of angiosperms (particularly the inverted repeat (IR) region in Corydalis adunca; (3) uniform inversion of The chloroplast genomes of at least some grasses have been known to possess three inversions relative to the typical gene arrangement found in most Since this event, chloroplast DNA has been massively transferred to the Chloroplast genome structure and gene order are also highly affected by inversions.

Chloroplast dna inversion

The chloroplast genomes of at least some grasses have been known to possess three inversions relative to the typical gene arrangement found in most flowering plants. We have surveyed for the presence of these inversions in grasses and other monocots by polymerase chain reaction amplification with primers constructed from sequences flanking the inversion end points. 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. We report here a survey of 50 genera of Phaseoleae and related tribes screened using small chloroplast DNA probes, whose hybridization patterns are diagnostic for the presence or absence of the inversion. 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).

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. Since Palmer (1983) originally doc-umented this phenomenon in Phaseolus vulgaris, it has been con- Species in 9 of the approximately 650 genera of the flowering plant family Leguminosae are known to possess a large (50-kb) inversion in their chloroplast genomes, relative to the gene order found most commonly among land plants. Putatively basal elements of the family have not been surveyed for the inversion, which is unknown outside the legumes.

We determined the distribution of a chloroplast DNA inversion among 80 species representing 16 tribes of the Asteraceae and 10 putatively related families. 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.

1985, 10: 139-145. CAS Article PubMed Google Scholar 34. 2021-03-31 · (2005) Kim et al. Molecular Biology and Evolution. 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. The entire chloroplast genome of the monocot rice (Oryza sativa) has been sequenced and comprises 134525 bp. Predicted genes have been identified along with open reading frames (ORFs) conserved between rice and the previously sequenced chloroplast genomes, a dicot, tobacco (Nicotiana tabacum), and a liverwort (Marchantia polymorpha).

17 Jan 2019 The chloroplast genome sequence was obtained via a mapping approach, region of 18182–18186 bp and two inverted repeats of 27026 bp.
