Cytoplasmic polymorphism and evolutionary history of plum cultivars: Insights from chloroplast DNA sequence variation of trnL-trnF spacer and aggregated trnL intron & trnL-trnF spacer

S. B. Mustapha, Ben Tamarzizt, H., Baraket, G., Abdallah, D., and Salhi-Hannachi, A., Cytoplasmic polymorphism and evolutionary history of plum cultivars: Insights from chloroplast DNA sequence variation of trnL-trnF spacer and aggregated trnL intron & trnL-trnF spacer, vol. 14, pp. 3964-3979, 2015.

We screened for polymorphisms of the non-coding region of plastid DNA in plum trees. Sequencing data from the trnL-trnF chloroplast region were used to reveal a pattern of diversity, establish phylogenetic relationships, and test the selection pressure or evolutionary demography scenario for plastome DNA. The size of the non-coding regions varied from 398 to 563 and 865 to 1084 bases pairs for the trnL-trnF spacer and combined sequences, respectively. The average GC contents were 33.8 and 34.4% in the spacer and pooled sequences, respectively.

tRNALeu intron (UAA) of Ficus carica L.: genetic diversity and evolutionary patterns

G. Baraket, Abdelkrim, A. B., and Salhi-Hannachi, A., tRNALeu intron (UAA) of Ficus carica L.: genetic diversity and evolutionary patterns, vol. 14, pp. 3817-3832, 2015.

Cytoplasmic chloroplast DNA was explored to establish genetic relationships among Ficus carica cultivars and elucidate the molecular evolution of the species. The results suggest the occurrence of haplotype and nucleotide diversity. Conserved group I intron sequence motifs were detected and showed a common secondary structure, despite the presence of some mutations on their sequences. The neighbor-joining dendrogram showed a continuous diversity that characterizes local resources.

Chloroplast DNA polymorphism and evolutional relationships between Asian cultivated rice (Oryza sativa) and its wild relatives (O. rufipogon)

W. J. Li, Zhang, B., Huang, G. W., Kang, G. P., Liang, M. Z., and Chen, L. B., Chloroplast DNA polymorphism and evolutional relationships between Asian cultivated rice (Oryza sativa) and its wild relatives (O. rufipogon), vol. 11, pp. 4418-4431, 2012.

We analyzed chloroplast DNA (cpDNA) polymorphism and phylogenic relationships between 6 typical indica rice, 4 japonica rice, 8 javanica rice, and 12 Asian common wild rice (Oryza rufipogon) strains collected from different latitudes in China by comparing polymorphism at 9 highly variable regions. One hundred and forty-four polymorphic bases were detected. The O. rufipogon samples had 117 polymorphic bases, showing rich genetic diversity.

Genetic variation of Kaempferia (Zingiberaceae) in Thailand based on chloroplast DNA (psbA-trnH and petA-psbJ) sequences

J. Techaprasan, Klinbunga, S., Ngamriabsakul, C., and Jenjittikul, T., Genetic variation of Kaempferia (Zingiberaceae) in Thailand based on chloroplast DNA (psbA-trnH and petA-psbJ) sequences, vol. 9, pp. 1957-1973, 2010.

Genetic variation and species authentication of 71 Kaempferia accessions (representing 15 recognized, six new, and four unidentified species) found indigenously in Thailand were examined by determining chloroplast psbA-trnH and partial petA-psbJ spacer sequences. Ten closely related species (Boesenbergia rotunda, Gagnepainia godefroyi, G. thoreliana, Globba substrigosa, Smithatris myanmarensis, S. supraneanae, Scaphochlamys biloba, S. minutiflora, S.
