First Report of the Natural Infection of Robinia pseudoacacia with Alfalfa mosaic virus

Chromatographic Analysis of the Flavonoids from Robinia Pseudoacacia Species

THE PURPOSE OF THIS STUDY WAS THE QUALITATIVE AND QUANTITATIVE ANALYSIS OF FLAVONOIDS FROM ROBINIA PSEUDOACACIA USING TWO DIFFERENT TECHNIQUES OF ANALYSIS: Thin Layer Chromatography (TLC) and TLC coupled with photo-densitometry. The results obtained by chromatographic analysis showed a higher concentration of flavonoids in flowers than in leaves. The flowers harvested in the plains have a highe...

Monocistronic translation of alfalfa mosaic virus RNAs.

The four alfalfa mosaic virus RNAs (respectively 24 S, 20 S, 17 S and 12 S) have been used separately as messengers in two in vitro protein synthesizing systems: wheat germ and rabbit reticulocyte lysate. In both systems a polypeptide corresponding to the translation of the entire length of the RNA can be found for RNAs 24 S, 20 S and 12 S, but not for 17 S RNA, the translation product of which...

Chemical composition and natural durability of juvenile and mature heartwood of Robinia pseudoacacia L.

The aim of this study was to characterize the properties of juvenile and mature heartwood of Robinia pseudoacacia L. (black locust). The content, the composition, and subcellular localization of heartwood extractives were studied in 14 old-grown trees from forest sites in Germany and Hungary, as well as in 16 younger trees of four clone types. Heartwood extractives (methanol and acetone extract...

Tubule-forming capacity of the movement proteins of alfalfa mosaic virus and brome mosaic virus.

The structural phenotype of the movement proteins (MPs) of two representatives of the Bromoviridae, alfalfa mosaic virus (AMV) and brome mosaic virus (BMV), was studied in protoplasts. Immunofluorescence microscopy showed that the MPs of these viruses, for which there has been no evidence of a tubule-guided mechanism, assemble into long tubular structures at the surface of the infected protopla...
