“…Brochidodromous (secondary veins joined into loops without previous branching) venation has been regarded as plesiomorphic, and craspedodromous venation has been regarded as a derived character state within angiosperms (Hickey and Wolfe 1975;Holländer and Jäger 1994;Roth-Nebelsick et al 2001). Present data do not support this hypothesis in Rosa unambiguously because molecular phylogenetic reconstructions of the genus lack statistical support and especially because basal branches were arranged in contradictory topologies (Wu et al 2001;Wissemann and Ritz 2005;Bruneau et al 2007;Koopman et al 2008). Rosa persica was sister to all other rose species in the phylogenies published by Wu et al (2001) and Wissemann and Ritz (2005).…”

Leaf fossils of Rosa lignitum Heer have often been documented as an accessory element in mixed mesophytic forests from the Oligocene and Miocene of central Europe. Its relationship to extant rose species is not yet firmly understood because leaf morphology contributes only marginally to the current taxonomy of the genus Rosa L. In this study, we investigate which extant rose species have structural leaf characters most similar to those of R. lignitum and whether the distribution and ecology of these extant species fit with the conditions hypothesized for the paleovegetation containing R. lignitum. Therefore, we examined the leaf characters of 32 extant rose species for their diagnostic value in taxonomy and compared these data with characters observed in R. lignitum from five Paleogene floras in central Europe. Most remarkably, we detected semicraspedodromous venation in R. lignitum. This venation pattern was found only in a few species of Rosa distributed in Southeast Asia, whereas the majority of extant rose species developed strictly craspedodromous venation. The distribution of extant species with semicraspedodromous venation in mixed broad-leaved deciduous and evergreen forests in subtropical China clearly corresponds to the hypothesized mixed mesophytic forests in the European paleovegetation. Thus, this study of detailed leaf morphology of Rosa again supports the previous assumption that the zonal vegetation of the central European Oligocene is partly comparable to extant forest types in Southeast Asia.

“…In roses, various sequences have been used (e.g. Matsumoto et al, 1998;Wisseman, 2002;Wu et al, 2001) but their interpretation was sometimes problematic (Ritz et al, 2005). In contrast, phenetic analyses, i.e.…”

The genus Rosa is usually subdivided into four subgenera, the largest of these is subgenus Rosa with 10 sections. Most of the genetically analysed rose species appear to be sexual and diploid (2n = 14) or tetraploid (2n = 28) although there are a few triploid (2n = 21), hexaploid (2n = 42) and octaploid species (2n = 56). The diploid species are usually self-incompatible whereas the polyploids are self-fertile. Pollen stainability is usually high in all species with even ploidy levels, i.e. 2x, 4x or 6x. Rose species are usually sexual and have a regular meiosis but there is one deviating section, Caninae, which harbours the so-called dogroses. Most of these are 5x but there are some taxa with 4x and 6x. Only seven chromosomes (derived from seven bivalents) are transmitted through the pollen grains, whereas egg cells contain 21, 28 or 35 chromosomes (derived from seven bivalents and 14, 21 or 28 univalents) depending on the ploidy level. Apomixis occurs occasionally in the dogroses and genetic selfing is probably common since these taxa are self-fertile. Interspecific hybridization takes place spontaneously among rose species at all ploidy levels and is used as a potent tool in plant breeding. Information about compatibility, breeding system, pollen viability, chromosome number and inheritance is important for optimal utilization of crosses in rose breeding.

“…The explorations of mei and plum products development have achieved enormous popularity. Applications of molecular approaches in classification have been extensively studied in recent decades (Kellogg & Appels, 1995;Persson, 2000;Tingey & Tufo, 1993;Woese, Gutell, Gupta, & Noller, 1983;Wu, Ueda, Nishihara, & Matsumoto, 2001;Zhang, Bao, & Chen, 1998). In the classification of Prunus, molecular method-based method has focused on the isozyme (Wang, Lu, & Guo, 1991), RAPD (Poon, 2000;Zhang et al, 1998), AFLP (Hagen, Khadari, Lambert, & Audergon, 2002) and amplification of some self-compatibility genetic markers in breeding (Tao, Habu, Yamane, Sugiura, & Iwamoto, 2002).…”
