Characterization of the complete chloroplast genome of sorrel (Rumex acetosa).

ABSTRACT: Rumex acetosa, known as sheep's sorrel, red sorrel, sour weed, and field sorrel, is a species of flowering plant in the buckwheat family Polygonaceae. In this study, the complete chloroplast (cp) genome of R. acetosa (Rumiceae) was determined through Illumina sequencing method. The complete chloroplast genome of R. acetosa was 160,269?bp in length and contained a pair of IR regions (30,503?bp) separated by a small single copy region (13,128?bp) and a large single copy region (86,135?bp). This cp genome is encoded with 129 genes including 83 protein-coding genes, 36 tRNA genes, and 8 ribosomal RNA genes. The overall GC content of R. acetosa cp genome is 37.2%. By phylogenetic analysis using Bayesian method, R. acetosa showed the closest relationship with other 2 Rumiceae species, Rheum palmatum and Oxyria sinensis.

Project description:Background and aimsDioecious species with well-established sex chromosomes are rare in the plant kingdom. Most sex chromosomes increase in size but no comprehensive analysis of the kind of sequences that drive this expansion has been presented. Here we analyse sex chromosome structure in common sorrel (Rumex acetosa), a dioecious plant with XY1Y2 sex determination, and we provide the first chromosome-specific repeatome analysis for a plant species possessing sex chromosomes.MethodsWe flow-sorted and separately sequenced sex chromosomes and autosomes in R. acetosa using the two-dimensional fluorescence in situ hybridization in suspension (FISHIS) method and Illumina sequencing. We identified and quantified individual repeats using RepeatExplorer, Tandem Repeat Finder and the Tandem Repeats Analysis Program. We employed fluorescence in situ hybridization (FISH) to analyse the chromosomal localization of satellites and transposons.Key resultsWe identified a number of novel satellites, which have, in a fashion similar to previously known satellites, significantly expanded on the Y chromosome but not as much on the X or on autosomes. Additionally, the size increase of Y chromosomes is caused by non-long terminal repeat (LTR) and LTR retrotransposons, while only the latter contribute to the enlargement of the X chromosome. However, the X chromosome is populated by different LTR retrotransposon lineages than those on Y chromosomes.ConclusionsThe X and Y chromosomes have significantly diverged in terms of repeat composition. The lack of recombination probably contributed to the expansion of diverse satellites and microsatellites and faster fixation of newly inserted transposable elements (TEs) on the Y chromosomes. In addition, the X and Y chromosomes, despite similar total counts of TEs, differ significantly in the representation of individual TE lineages, which indicates that transposons proliferate preferentially in either the paternal or the maternal lineage.
