Abstract
The genome composition of Beet necrotic yellow vein virus (BNYVV) was analysed in rootlets of field-grown sugar beets belonging to a variety which in spite of carrying the Rz1 resistance gene had developed strong rhizomania symptoms in a small area of France. This area was located in a borderline region between the distribution areas of P type BNYVV on one side and of A and B type BNYVV on the other. All five samples contained P type RNA 5. RNAs 1 to 4 were derived either solely from the A, B or P types or from mixtures of B and P types. It remains to be shown whether or not these RNA reassortments are responsible for the observed resistance breaking. By means of immunosorbent electron microscopy other sugarbeet viruses, i.e. Beet soil-borne virus, Beet virus Q, Beet mosaic virus, Turnip mosaic virus or Beet black scorch virus were not detected in these samples.
Zusammenfassung
Die Genom-Zusammensetzung des Beet necrotic yellow vein virus (BNYVV) wurde in Feldrüben-Wurzelproben einer Zuckerrübensorte untersucht, die trotz Rz1-Gen-vermittelter Rizomania-Resistenz in einem sehr begrenzten Gebiet in Frankreich starke Rizomania-Symptome entwickelt hatte. Dieses Gebiet liegt im Grenzbereich der Verbreitungsgebiete des P-Typs auf der einen Seite und des A- bzw. B-Typs auf der anderen. Alle fünf Proben enthielten P-Typ RNA 5. RNA 1 bis 4 gehörten entweder dem A-Typ, dem B-Typ oder dem P-Typ an. In einigen Fällen lagen Gemische von RNAs zweier verschiedener Genotypen vor. Ob diese heterologen RNA-Ge-mische für die beobachtete Resistenz-Brechung verantwort-lich sind, ist unklar. Immunelektronenmikroskopisch waren in diesen Proben weder Beet soil-borne virus, Beet virus Q, Beet mosaic virus, Turnip mosaic virus oder Beet black scorch virus nachweisbar.
