    Chilean potato germplasm with resistance to potato viruses Y and S (1993)
    Springer
    Euphytica 69 (1993), S. 135-140 
    Details
    ISSN: 1573-5060
    Keywords: Solanum tuberosum ssp. tuberosum ; Chilean potato germplasm ; resistance to potato viruses Y and S
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Four clones of the Chilota Potato Collection from the germplasm bank of the Universidad Austral de Chile, with potential combined resistance to PVX, PVY and PVS, were mechanically inoculated with these viruses in order to demonstrate wether they were truly resistant or not. Virus coat protein in the inoculated clones was determined by means of NCM-ELISA, DAS-ELISA, Western Blot and NASH. Two of the four inoculated clones were resistant to both PVY and PVS. This information will allow the utilization of these two clones in plant breeding programs.

    Notes: Abstract The phylogenetic distribution of transposable families, P, gypsy, hobo, I, and mariner has been analyzed in 33 species of 11 groups of neotropical Drosophila and a Drosophilidae species Zygotrica vittimaculosa, using squash blot and dot blot. Genomic DNA of almost all neotropical species tested hybridized with gypsy probe and some species showed a particularly strong hybridization signal, as D. gaucha, D. virilis, and species of flavopilosa group. The hobo element was restricted to melanogaster group and some strains of D. willistoni. Only D. simulans DNA showed hybridization to mariner probe in all species tested and D. simulans and D. melanogaster showed hybridization with I element probe. P element homologous sequence was present in D. melanogaster and all species and strains of the willistoni and saltans groups tested. The presence of at least one P-homologous sequence was detected in Drosophila mediopunctata. This one was the only P-bearing species of all six tested from the tripunctata group. Four different pairs of primers homologous to segments of the canonical sequence of D. melanogaster's P were used to amplify specific sequences from D. mediopunctata DNA, showing the occurrence of seemingly well-conserved P-homologous sequences.
