“…Many criteria have been used to support some taxonomic proposals such as seed morphology (Buth and Misri 1984), flower colour (Yokoi 1975), pollen exine (Ueda and Okada 1994), chromosome number (Lata 1982), DNA amount and polymorphism (Rajapakse et al 1992;Matsumoto et al 1997Matsumoto et al , 1998 and isozymes (Grossi et al 1997(Grossi et al , 1998. Some chemical markers, mainly phenolic compounds, have been used, too (Biolley et al 1994;Mikanagi et al 1995;Raymond et al 1995).…”

The oil content and fatty acids profile of a number of Polish wild species of rose fruits were examined by GC. The total fatty acid contents ranged from 6.5% to 12.9% of dry mass in fruits. The composition of oils was similar in the investigated species.17 components were identified. An average composition was estimated as follows: linoleic acid (44.4-55.7%), =-linolenic acid (18.6-31.4%), oleic acid (13.5-20.3%), palmitic acid (2.3-3.3%), stearic acid (1-2.5%), octadecenoic acid (0.38-0.72%), eicosenoic acid (0.3-0.7%), eicosadienoic acid (0-0.16%), erucic acid (0.03-0.17%) and minor fatty acids.The results indicate that rose fruits are a rich source of unsaturated fatty acids, especially in R. rubiginosa, R. rugosa and R. dumalis.There were statistically significant (p<0.05) differences in fatty acid compositions of some species. Fatty acids were suggested to have a potential chemotaxonomic value in this genus.KEY WORDS: Fatty acids composition, Rosa L. fruits, GC analysis. MATERIAL AND METHODS Plant materialRose hips were collected from bushes widely growing in Kazimierz Dolny near Lublin in Poland in September 2002 and authenticated by Prof. Dr T. Krzaczek. Names of species are those by Zieliñski (1985Zieliñski ( , 1987 and varieties by Popek (1996). A voucher specimens have been deposited in the herbarium of Department of Pharmaceutical Botany, Medical University, in Lublin. The examined species are given in Table 1. 230 Nowak R.

“…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.

“…Modern roses (Rosaϫhybrida) have resulted from extensive hybridization of wild rose species (Matsumoto et al 1998). Flower traits such as floral architecture, petal color, and recurrent flowering are key characters that have been subjected to artificial selection pressure during domestication and crossbreeding.…”

Morphological changes of Rosa×hybrida by a chimeric repressor of Arabidopsis TCP3

Chimeric repressor gene-silencing technology is a useful tool for changing morphology of ornamental plants. It has previously been demonstrated that the chimeric repressor TCP3SRDX, which consists of Arabidopsis TCP3 and an ERF-associated amphiphilic repression motif repression domain, perturbs the marginal morphology of Arabidopsis leaves and flowers. To obtain new rose cultivars that have ornamental values, we attempted to alter the morphology of Rosaϫ hybrida cv. Lavande with TCP3SRDX. The TCP3SRDX transgenic rose plants showed interesting phenotypes: the number of leaflets and the size of leaf teeth increased, the petals were wavy, and the sepals were compound-leafy. We succeeded in altering rose morphology using Arabidopsis TCP3 without the sequence information of a TCP3 homologue in the target plant species.
