Plant Genetic Resources

Publisher: National Institute of Agricultural Botany (Great Britain), Cambridge University Press


Plant Genetic Resources is an international journal that brings together the many diverse topics concerned with plant genetic resources. Each issue gives you access to peer-reviewed research papers on genetic variation in plants, both crop and non-crop, as well as on the technical, socio-economic, legal and geo-political aspects of PGR. Many papers feature research directed to endangered non-crop and medicinal plants. The journal is of interest to researchers and scientists involved in the plant genetic resources community, including: breeders, all those with an interest in germplasm, policy makers, consultants and research students.

    ABSTRACT: To evaluate the genetic diversity (GD) of wild and cultivated soybeans and determine the genetic relationships between them, in this study, 127 wild soybean accessions and 219 cultivated soybean accessions were genotyped using 74 simple sequence repeat (SSR) markers. The results of the study revealed that the GD of the wild soybeans exceeded that of the cultivated soybeans. In all, 924 alleles were detected in the 346 soybean accessions using 74 SSRs, with an average of 12.49 alleles per locus. In the 219 cultivated soybean accessions, 687 alleles were detected, with an average of 9.28 alleles per locus; in the 127 wild soybean accessions, 835 alleles were detected, with an average of 11.28 alleles per locus. We identified 237 wild-soybean-specific alleles and 89 cultivated-soybean-specific alleles in the 346 soybean accessions, and these alleles accounted for 35.28% of all the alleles in the sample. Principal coordinates analysis and phylogenetic analysis based on Nei's genetic distance indicated that all the accessions could be classified into two major clusters, corresponding to wild and cultivated soybeans. These results will increase our understanding of the genetic differences and relationships between wild and cultivated soybeans and provide information to develop future breeding strategies to improve soybean yield.

    ABSTRACT: The development of modern approaches to the genetic improvement of the tree crop Ilex paraguariensis (‘yerba mate’) and Ilex dumosa (‘yerba sen ˜orita’) is halted by the scarcity of basic genetic information. In this study, we characterized the implementation of low-cos methodologies such as representational difference analysis (RDA), single-strand conformation polymorphisms (SSCP), and reverse and direct dot-blot filter hybridization assays coupled with thorough bioinformatic characterization of sequence data for both species. Also, we estimated the genome size of each species using flow cytometry. This study contributes to the better understanding of the genetic differences between two cultivated species, by generating new quantitative and qualitative genome-level data. Using the RDA technique, we isolated a group of non-coding repetitive sequences, tentatively considered as Ilex-specific, which were 1.21- to 39.62-fold more abundant in the genome of I. paraguariensis. Another group of repeti tive DNA sequences involved retrotransposons, which appeared 1.41- to 35.77-fold more abundantly in the genome of I. dumosa. The genomic DNA of each species showed differen performances in filter hybridizations: while I. paraguariensis showed a high intraspecific affinity I. dumosa exhibited a higher affinity for the genome of the former species (i.e. interspecific) These differences could be attributed to the occurrence of homologous but slightly divergen repetitive DNA sequences, highly amplified in the genome of I. paraguariensis but not in the genome of I. dumosa. Additionally, our hybridization outcomes suggest that the genomes o both species have less than 80% similarity. Moreover, for the first time, we report herein a genome size estimate of 1670Mbp for I. paraguariensis and that of 1848Mbp for I. dumosa.

    ABSTRACT: The wheat landraces collected by Dr Hitoshi Kihara et al. from Afghanistan, the place of secondary origin of wheat, are an untapped genetic resource for mining novel alleles. In this study, approximately 400 landraces were collected from seven agroecological zones and characterized using diversity array technology and single-nucleotide polymorphism markers, as well as diagnostic molecular markers at important loci controlling vernalization (Vrn), photoperiod response (Ppd), grain colour (R), leaf rust (Lr), yellow rust (Yr), stem rust (Sr) and Fusarium head blight (Fhb). A genome-wide marker array revealed a large amount of genetic diversity among the landraces, 53% of which were winter types, 43% were either spring types or facultative and 4% were either unknown or had Vrn-A1c – a rare spring allele that needs to be confirmed with additional genotyping and phenotyping. At Ppd, 97% of the lines carried a photosensitive allele. In the case of grain colour, classification based on dominant or recessive allelic combinations revealed that approximately 39% of the population is characterized by white grain. Four gene-specific markers that were targeted to identify loci for rust and Fhb resistance enabled us to identify 17 unique landraces with known resistance genes.

    ABSTRACT: Rhazya stricta is an endangered medicinal plant that is under severe human pressure as a result of commercial harvesting. As a model of habitat fragmentation, we selected the Kohat Plateau in the Pakistani Himalaya, where populations are fragmented, with less than 100 individuals per population. We hypothesized that the populations may be threatened by rapid habitat fragmentation and by unsustainable utilization of the plant. We analysed P450-based analogue functional genomic markers and amplified fragment length polymorphism markers from six populations of R. stricta on the Kohat Plateau, and examined their variations both within and among the populations. Both the marker groups revealed lower genetic differentiation among the populations and higher genetic differentiation within the populations as a result of high gene flow. The results confirmed that habitat fragmentation is being caused by severe human pressure, and although signs of genetic erosion are not yet visible, they seem likely to become visible in the future. Therefore, the conservation of R. stricta populations is necessary.
