Genetic differentiation of three endangered wild roses in northeastern Germany: Rosa inodora Fries, Rosa sherardii Davies and Rosa subcollina (H. Christ) Keller.
Jürgens AH, Seitz B, Kowarik I. Jürgens AH, et al. Plant Biol (Stuttg). 2011 May;13(3):524-33. doi: 10.1111/j.1438-8677.2010.00406.x. Epub 2010 Nov 19. Plant Biol (Stuttg). 2011. PMID: 21489104
To obtain information about population distinctiveness of endangered Rosa species occurring in Brandenburg (northeast Germany), we investigated the genetic differentiation of Rosa inodora, R. sherardii and R. subcollina using RAPD markers. ...Due to predomina …

Skewed distribution of morphological character scores and molecular markers in three interspecific crosses in Rosa section Caninae.
Werlemark G, Nybom H. Werlemark G, et al. Hereditas. 2001;134(1):1-13. doi: 10.1111/j.1601-5223.2001.00001.x. Hereditas. 2001. PMID: 11525060 Free article.
The dogroses, Rosa section Caninae, are all polyploid and characterised by their unbalanced meiosis; the pollen parent contributes one genome, whereas the seed parent contributes 3-5 genomes depending upon ploidy level of the species. ...The plant material consisted of a p …

Frequent silencing of rDNA loci on the univalent-forming genomes contrasts with their stable expression on the bivalent-forming genomes in polyploid dogroses (Rosa sect. Caninae).
Khaitová L, Werlemark G, Nybom H, Kovarík A. Khaitová L, et al. Heredity (Edinb). 2010 Jan;104(1):113-20. doi: 10.1038/hdy.2009.94. Heredity (Edinb). 2010. PMID: 19639009
The polyploid species in Rosa section Caninae (2n=21, 28 or 35) are characterized by an unusual reproductive system known as odd (or asymmetric) meiosis. ...Here, we have investigated expression of rRNA gene families in five pentaploid species (R. canina, R. rubiginosa, R. …
The polyploid species in Rosa section Caninae (2n=21, 28 or 35) are characterized by an unusual reproductive system known as odd (or …
Microsatellite DNA marker inheritance indicates preferential pairing between two highly homologous genomes in polyploid and hemisexual dog-roses, Rosa L. Sect. Caninae DC.
Nybom H, Esselink GD, Werlemark G, Vosman B. Nybom H, et al. Heredity (Edinb). 2004 Mar;92(3):139-50. doi: 10.1038/sj.hdy.6800332. Heredity (Edinb). 2004. PMID: 14981531
According to previous cytological evidence, the hemisexual dog-rose species, Rosa sect. Caninae, transmit only seven chromosomes (derived from seven bivalents) through their pollen grains, whereas egg cells contain 21, 28 or 35 chromosomes (derived from seven bivalents and …
