Comparative analysis of 11 Brassicales mitochondrial genomes and the mitochondrial transcriptome of Brassica oleracea

Plant Mitochondrial Genome Evolution and Cytoplasmic Male Sterility

“…is multipartite, consisting of six master circles and four smaller subgenomic circles which likely result from repeat-induced genomic reorganization . A similar configuration has been observed in Brassica oleracea, which displays a tripartite structure consisting of a 220 kb master circle that is also split into two subgenomic circles (170 and 50 kb each) via homologous recombination of repeated sequences (Grewe et al, 2014). Observations in the hau CMS line of Brassica and its maintainer line in B. juncea suggest not only a multipartite structure, but also the substoichiometric coexistence of different mitotypes (Heng et al, 2014).…”

“…Post-transcriptional RNA editing of mitochondrial genes is both ubiquitous and important for regulation (Marchfelder and Binder, 2004;Takenaka et al, 2008;Wang et al, 2009;Grewe et al, 2014). Typically, RNA editing of mitochondrial transcripts in flowering plants occurs in coding regions of mitochondrial transcripts (Hanson et al, 1996) to convert specific cytosine residues to uracil (C !…”

Detection of differentially methylated regions of irradiated fig tree selections

“…The sequencing and the analysis of the methylation points can be seen in Figure 1. The search for a similar sequence, using the BLAST software, resulted in significant alignment in the NCBI database with the mitochondrial DNA of the following plant species: tulip (Richardson et al, 2013), castor oil plant (Rivarola et al, 2011), watermelon (Alverson et al, 2010), melon (Rodríguez-Moreno et al, 2011), saltbush (Grewe et al, 2014), papaya (Rice et al, 2008) and tobacco (Sugiyama et al, 2005), amongst others, with an E-value of 1e-72, 2e-127, 2e-57, 3e-36, 2e-46, 2e-39 and 2e-39 respectively (Figure 2).…”

A Primer to Molecular Phylogenetic Analysis in Plants

“…However, the mitochondrial genome seems to be not as well-suited for plant phylogenetic analyses. Due to a high frequency of rearrangements, gene order and content of the plant MOLECULAR PHYLOGENETIC ANALYSIS IN PLANTS mitochondrial genome is poorly conserved across plants (Duff and Nickrent, 1999;Knoop, 2004;Knoop et al, 2011;Grewe et al, 2014). In addition, horizontal gene transfer among plant mitochondrial genomes is more common compared to plastid and nuclear genomes (Bergthorsson, 2003;Sanchez-Puerta et al, 2008;Sanchez-Puerta et al, 2011;Xi et al, 2013).…”
