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.

Genetic diversity and differentiation in Prunus species (Rosaceae) using chloroplast and mitochondrial DNA CAPS markers

S. Ben Mustapha, Ben Tamarzizt, H., Baraket, G., Abdallah, D., and A. Hannachi, S., Genetic diversity and differentiation in Prunus species (Rosaceae) using chloroplast and mitochondrial DNA CAPS markers, vol. 14, pp. 4177-4188, 2015.

Chloroplast (cpDNA) and mitochondrial DNA (mtDNA) were analyzed to establish genetic relationships among Tunisian plum cultivars using the polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) technique. Two mtDNA regions (nad 1 b/c and nad 4 1/2) and a cpDNA region (trnL-trnF) were amplified and digested using restriction enzymes. Seventy and six polymorphic sites were revealed in cpDNA and mtDNA, respectively. As a consequence, cpDNA appears to be more polymorphic than mtDNA.

Confirmation of a purple-leaved plum graft hybrid

X. M. Zhou, Liu, Y. S., and Li, X. J., Confirmation of a purple-leaved plum graft hybrid, vol. 12. pp. 710-713, 2013.

Fifty-seven scions from an adult purple-leaved plum tree were grafted onto the crown of a 6-year-old Yuhuang plum tree and compared to the control of a non-grafted tree. The floral buds of the purple-leaved plum were fully removed before blossoming to avoid sexual hybridization between the two species. The seeds of the Yuhuang plum were picked in July and sown in the spring after stratification. Three, eleven and eight variants with purplish red leaves were found among the seedlings that grew from the seeds picked in 1999, 2000, and 2001, respectively.

Molecular analysis of East Anatolian traditional plum and cherry accessions using SSR markers

M. H. Öz, Vurgun, H., Bakir, M., Büyük, İ., Yüksel, C., Ünlü, H. M., Çukadar, K., Karadoğan, B., Köse, Ö., and Ergül, A., Molecular analysis of East Anatolian traditional plum and cherry accessions using SSR markers, vol. 12, pp. 5310-5320, 2013.

We conducted SSR analyses of 59 accessions, including 29 traditional plum (Prunus domestica), 24 sweet cherry (Prunus avium), and 1 sour cherry (Prunus cerasus) selected from East Anatolian gene sources and 3 plum and 2 cherry reference accessions for molecular characterization and investigation of genetic relationships.
