Abstract
A selected panel of 13 colonies of entomopathogenic fungus Conidiobolus coronatus representing 6 variants of pathogenicity to Galleria mellonella larvae (ranged from 100 to 10% of efficiency), derived from single spores, were tested for the presence of hypervariable loci in their genomes by hybridization with Jeffreys' human minisatellite probe 33.6. The probe produced informative fingerprints and revealed slight differences among colonies analyzed. Up to 20 variable bands per colony were recognized in the size range of 2-20 kb. The band sharing within groups with the same pathogenicity ranged from 0.966 to 0.800. The genetic distance between different variants ranged from 0.026 to 0.282. A few characteristic bands for high and low pathogenicity to the larvae were found.

Abstract
In order to investigate the intraspecific variation of Prunus yedoensis (Someiyoshino) and interspecific relationship among P. yedoensis, P. lannesiana (Oshimazakura) and P. pendula (Edohigan), DNA fingerprinting study was conducted by using two different kinds of probes, M13 repeat sequence and (GACA)4 synthetic oligonucleotide. In this study, 68 plants of P. yedoensis grown in 46 prefectures in Japan were investigated. All the P. yedoensis individuals investigated showed the completely same banding pattern, indicating their clonal origin from a single plant. On the other hand, each of P. lannesiana and P. pendula individuals investigated showed a unique banding pattern, suggesting a considerable amount of genetic variation in these two species. About 90% of bands in DNA fingerprints of P. yedoensis were detected in either P. lannesiana or P. pendula. This result supports the hypothesis that P. yedoensis is an interspecific hybrid between P. lannesiana and P. pendula. From those results, it is concluded that P. yedoensis was produced only once through hybridization between P. lannesiana and P. pendula, and that this particular hybrid plant has been spread vegetatively all over Japan.

Abstract
A strategy based on random PCR amplification was used to isolate new repetitive elements of Arabidopsis thaliana. One of the random PCR product analyzed by this approach contained a tandem repetitive minisatellite sequence composed of 33 bp repeated units. The genomic locus corresponding to this PCR product was isolated by screening a lambda genomic library. New related loci were also isolated from the genomic library by screening with a 14 mer oligonucleotide representing a region conserved among the different repeated units. Alignment of the consensus sequence for each minisatellite locus allowed the definition of an Arabidopsis thaliana core sequence that shows strong sequence similarities with the human core sequence and with the generalized recombination signal Chi of Escherichia coli. The minisatellites were tested for their ability to detect polymorphism, and their chromosomal position was established.

Abstract
Simple sequence repeat oligonucleotides were used to probe the tomato genome for elements displaying variability amongst commercial cultivars. The oligonucleotide (GACA)4 was found to be particularly informative on genotype screening blots, hybridising to a highly polymorphic family of elements, and was used to clone one such member from a lambda library. The GACA-hybridisation was localised to a 1.3-kbHinfI fragment within the original 15-kb lambda insert. This 1,349-bp subclone (pT-GACA-2:1.3) was used to probe 27 Californian processing varieties and found to be capable of distinguishing all from each other, thus demonstrating its utility as a genetic fingerprinting probe for cultivar identification. Hybridisation occurred to approximately 10 major high molecular weight (> 4-kb) bands, most of which segregated independently in F2 populations, as well as a large number of less clearly resolvable smaller fragments. Sequence analysis of the cloned element reveals that it is almost entirely composed of GACA or GATA repeats. These tetranucleotides are organised into distinct repetitive domains, consisting either of tandem arrays of each tetranucleotide or interspersions of GACA and GATA to form dodecanucleotides that are then further repeated. The boundaries between domains contain sufficient departures from the concensus repeat to allow construction of unique polymerase chain reaction (PCR) primers. Amplification from two such contiguous regions identifies length variation in both, thus yielding a genotype screen appropriate for high-throughput applications, such as assessment of purity in F1 hybrid seed lots.

Abstract
Various methods from molecular biology reveal sequence polymorphisms in organelle and nuclear DNA that can be used as highly informative markers for the structure and dynamics of genomes at the level of populations and individuals. Molecular markers that can be determined without regard to the phenotype permit an unbiased comparison of the adaptation of organisms to their environment, its genetic basis and its effect on evolution. Several marker types used in ecological research and their uses and limitations arc briefly discussed. PCR-based methods, especially arnitrary-primer-based RAPDs, are likely to be most widely used and receive most attention. The limited use of DNA markers for overall quantitative (phenetic) comparisons of 'genetic variability' and 'generic distance' is stressed and fheir power as qualitative markers for any and all relevant regions in the genome is emphasized. Specific applications relevant to plant ecology are illustrated. These are: identification of organism and genotype even where morphology is of little help, as in mycorrhiza; identification of clones in asexually-reproducing species, even when they are widespread and intermingled; determining if genetic variation in elonal populations comes from mutations within elonal lines or from independent origins of clonal lines; reconstructing the genotype phylogeny and fruit dispersal of elonal (apomicuc) and inbred selling organisms, measuring the degree of outcrossing by offspring exclusion analysis; detecting and analyzing introgression and characterizing reeombinant genotypes in hybrid zones relative to differential adaptive responses: tracing the phylogenetic origin and extent of ecologically differentiated races or species; characterizing the genetic basis, mapping and isolating the genes responsible for special adaptive responses. In a final outlook, 1 speculate about unconventional sources of genetic variation affecting the ecological characteristics of plants that will become accessible to experimental analysis with the new molecular methods.

Abstract
DNA fingerprints generated by the Jeffreys' probes, 33.6 and 33.15, indicated the presence of minisatellite-like sequences in the red clover genome. The fingerprints generated by probe 33.6 gave less background and fewer but better defined bands than those obtained with probe 33.15. Assay of a regenerative somaclonal variant (F49R) by DNA fingerprinting with probe 33.6 detected mutation that was unlinked to the regenerative trait. The fingerprints obtained under the applied conditions also demonstrated genetic stability of consecutive generations of the regenerants in tissue culture. DNA fingerprints of F1 plants revealed that each polymorphic band was inherited from either one or the other parent. Both probes distinguished individual-specific genotypes in seven cultivars of red clover. Greater variability in DNA fingerprints was detected between (V=0.899) than within (0.417≤V≤0.548) cultivars.

Abstract
Bamboo species are difficult to identify because flowering material is seldom available and taxonomy is of necessity based on vegetative characters. To evaluate the utility of restriction fragment length polymorphism (RFLP) analysis in bamboo systematics and germplasm screening, a library of random genomic probes from a Phyllostachys nigra PstI library was constructed. Probes from the library were used to screen bamboo germplasm consisting mostly of temperate bamboos of the genus Phyllostachys. RFLP variation was abundant, and species-specific patterns were readily obtained. Chloroplast DNA showed little variation among the bamboo accessions analyzed.

Abstract
The existence of hypervariable DNA sequences in nuclear genomes, and the use of appropriate "fingerprinting" probes to detect them, has gained widespread scientific interest, and also led to multiple applications in diverse areas. Two years ago, the new technique of "DNA fingerprinting" was also introduced into the analysis and characterization of plant genomes, initially by using human or M13 minisatellites as probes. In the present article, we demonstrate the applicability for plant DNA fingerprinting of oligonucleotide probes specific for simple repetitive DNA sequences. We show that various levels of intra- and interspecific polymorphisms can be detected; the information to be gained depends on the optimal combination of probe and species. Variety-specific patterns were obtained in several cases. Some probes revealed variability between individuals. Somatic variability was not observed. Different DNA isolation and purification procedures were tested in order to introduce a fast and easy-to-perform isolation method suitable for a large variety of plant species. Nonradioactive fingerprinting was performed using digoxigenated oligonucleotides as probes. Banding patterns obtained with radioactive and digoxigenin-based labeling techniques proved to be of similar quality.

Abstract
In the last decade RFLP analysis has evolved from an idea that seemed promising to a well-established tool that has led to fundamental advances in several fields. Construction of genetic maps has now become feasible in many organisms where it would previously have been impractical. Since genetic maps are of general utility for many sorts of biological research, they cannot fail to have a significant impact in the immediate future. As genetic maps become reconciled with physical maps in several plants, it will become possible to clone virtually any gene. For a plant breeder this will have the effect of broadening the gene pool available for plant improvement to include virtually all organisms, including animals and microorganisms. Much remains to be done, however. We need basic studies of the biochemistry, physiology, and genetics of plants and the insects and pathogens infesting them to be able to identify target genes for cloning. We need basic studies of transformation and gene expression to be able to have introduced genes expressed in transformed plants in the proper amounts and in the desired tissues. It must also be kept in mind that the best of our present technologies only suffice to clone and transform single genes. We will have to make another large jump in capabilities to be able to transfer QTL between plants. Since the most important agronomic traits are controlled by QTL, this effort will have to be undertaken. However, the future looks promising for plant breeding and RFLP analysis. The molecular genetic revolution now has every indication of being transferrable to practical problems such as plant breeding, and the first steps in this transferral have already occurred through the medium of RFLP analysis.

Abstract
We have isolated DNA probes, homologous to the human hypervariable minisatellite sequence 33.15, from the genome of rice (Oryza sativa). These probes are capable of producing a multilocus rice DNA fingerprint. The rice sequence has a tandem repeating structure based on a 12 bp GC-rich repeat which shows homology to its human counterpart. This probe detects up to 30 loci which are at a number of unlinked chromosomal sites. The GC-rich sequence is invariably associated with an open reading frame (ORF) of unknown function. The ORF is probably a member of a small multigene family.
