| Popis: | Bacilliform particles characteristic of plant rhaboviruses were found in ultrathin sections of Laburnum anagyroides growing in a park in Zagreb (Yugoslavia). Specimens of Laburnum in which bacilliform virions were present showed only yellowing along the main veins but not mosaic symptoms. Virus particles were found in yellow areas of the leaflets and were situated in the nucleus as well as in the cytoplasm. Results of this investigation support the opinion of Schultz and Harrap (1975) that the vein yellowing symptoms on L. anagyroides are provoked by a rhabdovirus named by them laburnum yellow vein virus. U ultratankim presjecima kroz lisno tkivo grmova vrste Laburnum anagyroides Medic, (zanovijet) koji pokazuju simptome žućenja duž glavnih nerava utvrđena je prisutnost baciliformnih čestica karakterističnih za biljne rabđoviruse. Čestice su nađene u parenhimskim stanicama iz područja žutih promjena uz nerve, a lokalizirane su i u perinuklearnom prostoru i u citoplazmi. Prisutne su kratke i duge čestice. U srži dugih čestica zapažena je poprečna pukotina koja upozorava na mogućnost da je u takvim česticama uklopljen dvostruki genom. Rezultati istraživanja izneseni u ovom radu podupiru nalaz i mišljenje Schultza i Harrapa (1975) da simptome žućenja nerava u vrste L. anagyroides uzrokuje jedan rabdovirus veličine 245 X 89 nm, za koji su predložili naziv virus žutih nerava zanovijeti (laburnum yellow vein virus). |
