    Optimizing the generation of random amplified polymorphic DNAs in chrysanthemum (1993)
    Springer
    Theoretical and applied genetics 86 (1993), S. 1033-1037

    ISSN: 1432-2242
    Keywords: RAPDs ; Experimental design ; Fractional factorial ; Chrysanthemum ; PCR

    Notes: Abstract Many conditions of the RAPD reaction procedure may influence the result. This paper presents rapid detection of influential factors with a fractional factorial experiment. A more extensive study of these factors is also presented. Polymerase brand, thermal cycler brand, annealing temperature, and primer, are important factors in obtaining good DNA yields and optimal fragment patterns. Each primer has its optimal annealing temperature, and this is not correlated with the GC content of the primer. Optimal species-primer combinations have to be found by trial and error.

    RFLP analysis in chrysanthemum. I. Probe and primer development (1994)
    Springer

    Notes: Abstract In order to study genetic variability at the DNA level in chrysanthemum (Dendranthema grandiflora Tzvelev) PstI and HindIII genomic libraries were constructed. Probes from both libraries were tested for the presence of restriction fragment length polymorphisms (RFLPs). Of the probes from the PstI library 91% appeared to hybridize to low-copy genes, while only 35% of those from the HindIII library appeared to do so. The PstI probes were used in further analyses as 79% of them showed RFLPs, whereas the HindIII low-copy number probes gave only 14% polymorphic patterns. Because of the hexaploid character of chrysanthemum, complex patterns generally consisting of 6–12 fragments were visible on a Southern blot after hybridization. To simplify the genetic analysis, locus-specific polymerase chain reaction (PCR) primers were developed that gave simple polymorphic patterns in a number of cases. The RFLP probes and primers developed will be used in future marker-assisted selection in this polyploid crop.

    Identification of chrysanthemum cultivars and stability of DNA fingerprint patterns (1995)
    Springer
    Theoretical and applied genetics 91 (1995), S. 439-447 
    Details
    ISSN: 1432-2242
    Keywords: Chrysanthemum ; RAPD ; DNA fingerprint ; RFLP ; Stability

    Topics: Biology
    Notes: Abstract Several techniques of DNA analysis were applied to identify chrysanthemum cultivars. Unrelated cultivars could be distinguished by using RAPDs (random amplified polymorphic DNAs), inter-SSR (simple sequence repeat) PCR (polymerase chain reaction), hybridization-based DNA fingerprinting, as well as RFLPs (restriction fragment length polymorphisms). Cultivars with different flower colours and belonging to one family, i.e. vegetatively derived from 1 cultivar, appeared to have the same DNA fragment patterns, whichever technique was applied. The absence of polymorphisms between different accessions of the same cultivar indicated a high stability of the observed patterns.
