SummarySeven wildPetunia species including 2n = 18 species (P. parviflora Jussieu,P. linearis Hook.) and those with 2n = 14 (P. parodii Steene,P. axillaris Lam.,P. integrifolia Hook.,P. inflata R.E. Fries,P. violacea Lindl.) and tenPetunia hybrida horticultural lines were compared for polymorphisms in rDNA genes using the four restriction enzymesEcoRI,BamHI,HindIII andXhoI. All the unit types found in the lines pre-existed in the wild forms. There are two different sizes of either 11.45 or 11.6… 

Phylogenetic analysis of the genus Petunia (Solanaceae) based on the sequence of the Hf1 gene

A nuclear gene, Hf1, seems to be a useful molecular marker for elucidating the phylogeny of the genus Petunia when compared with the nucleotide sequence of trnK intron of chloroplast DNA.

Phylogenetic analysis of Petunia sensu Jussieu (Solanaceae) using chloroplast DNA RFLP.

Several clades found in the phylogenetic trees corresponded to their distribution ranges, suggesting that recent speciation in the genus Petunia sensu Jussieu occurred independently in several different regions.

Phylogenetic relationships in the North African genus Hedysarum as inferred from ITS sequences of nuclear ribosomal DNA

The great similarity of the ITS sequences between H. coronarium and H. carnosum suggests the usefulness of the latter in selection programmes to improve pastoral production in semi-arid areas and the level of variation was high enough to make the ITS1 and ITS2 a useful tool for phylogenetic reconstruction.

Molecular discrimination among taxa of Petunia axillaris complex and P. integrifolia complex based on PolA1 sequence analysis

The 19th intron and the 20th exon of the PolA1 gene, a single gene encoding the largest subunit of RNA polymerase I, are sequenced and shown clear differences between P. axillaris complex and P. integrifolia complex, and also among all the taxa within each complex.

Molecular Evidence for Progenitorial Species of Garden Petunias Using Polymerase Chain Reaction : Restriction Fragment Length Polymorphism Analysis of the Chs-j Gene

The results indicate that the wild species analyzed here might partially have contributed to the Chs-J gene of garden petunias analyzed and demonstrate the use of PCR-RFLP in establishing relationships among closely related species and cultivars of Petunia.

Hedysarum phylogeny mediated by RFLP analysis of nuclear ribosomal DNA – RFLP and Hedysarum phylogeny

The RFLP technique was employed to investigate phylogenetic relationships between species of the Hedysarum genus and homologous DNA probes were used to generate patterns from a set of the Mediterranean group, in good agreement with phylogeny based on morphological and isozyme markers.

Genetic differentiation in the olive complex (Olea europaea) revealed by RAPDs and RFLPs in the rRNA genes

A low interspecifc differentiation was found in the Mediterranean olive, suggesting a recent genetic divergence between the different taxa of the O. europaea complex or the occurrence of gene flow during favourable periods or because human displacements.

Research in plant genetic resources 1978–2003: General index of the second 25 volumes 'Kulturpflanze'/'GRACE'

A general index of the second 25 volumes of 'Kulturpflanze' 1978–1990/'GRACE' (Genetic Resources and Crop Evolution) 1992–2003 is provided and can be considered as a unique source for research in plant genetic resources.



Characterization of the nuclear ribosomal DNA units and phylogeny of Beta L. wild forms and cultivated beets

It is deduced that all the cultivated forms of beets likely originated in a unique plant ascendant, and a phylogenic tree of the genus Beta is proposed, based on the nuclear rDNA maps, and subsequently discussed relative to the systematic tree and other molecular phylogenies.

On the interrelationships of certain species of Petunia IV: Hybridization between P. linearis and P. calycina and nomenclatorial consequences in the Petunia group

Analysis of meiotic prophase microsporocytes of the hybrids reveals bivalents with almost complete pairing, indicating large scale homology between both genomes.

Organization and evolution of the 5S ribosomal RNA gene family in wheat and related species

The umbellulatum for 'Chinese Spring' chromosomes were used to identify chromosomal loci of 5S rRNA genes (5S DNA) in wheat and related species and concerted evolution of the 5S DNA loci was examined in several genomes.


Three inbred marker lines of Petunia hybrida Vilm. carrying independently inherited monogenic characters (apt, apetalous flower; D flower doubleness; G grandiflora plant and flower) were hybridized

Ribosomal gene spacer length variability in cultivated and wild rice species

Restriction fragment length polymorphism of the rDNA spacer was studied in the genus Oryza using a cloned rice rDNA probe and a general tendency from a smaller spacer in the Japonica subtypes to longer ones in Indica is observed.

Molecular evidence for genetic exchanges among ribosomal genes on nonhomologous chromosomes in man and apes.

We have found that human and ape ribosomal genes undergo concerted evolution involving genetic exchanges among nucleolus organizers on nonhomologous chromosomes. This conclusion is based upon


It is concluded that only two biological species are involved in the described species Petunia axillaris, the white-flowered P. axillari and the purple-flowers P. integrifolia.

Characterisation of the genes for ribosomal RNA in flax.

DNA coding for the 18S and 25S rRNAs in flax has been purified and is arranged in tandem arrays with a repeat length of 8.6 kb, and the cloned rDNA has been used to compare two genotrophs where the number of rRNA cistrons has been altered by growth under different environmental conditions.


Two species of Petunia, P. linearis and P. calycina, were grown from seed collected in the wild and seem to be related to P. parviflora, which found support in peroxidase isozyme data.

Organization of the 5S ribosomal RNA genes in the genome of tomato

A detailed characterization of the 5S rRNA genes of tomato with respect to chromosome assignment, chromosomal localization, copy number, and physical size is reported.
