Background. Grapevine leafroll disease is one of the most widespread viral diseases in vineyards, affecting nearly all grape and wine regions in the world. Infection causes yield losses, ripening delays, and alters fruit chemistry, including lowering soluble solids and increasing titratable acidity. The viruses associated with leafroll disease are transmitted through propagation of infected mat...

A method for preparing elicitor-responsive protoplasts from grapevine cells kept in suspension culture was established. The protoplasts were employed in order to perform transient gene expression experiments produced by externally added plasmids. Using the gene coding for bacterial beta-glucuronidase as the reporter gene, the transient expression under the control of various promoters of stilbe...

• The bell-pepper aroma typical of Cabernet Sauvignon and Sauvignon blanc has been correlated with the corresponding concentration of isobutyl-methoxypyrazine (IBMP). However, the term “vegetal” can include aromas other than bell-pepper. For example, many sulfur-containing compounds can elicit vegetal notes (e.g. asparagus, cooked corn, boxwood, rubber), and so can the norisoprenoid class of co...

In this study, we investigate the relation between explant size and success of virus elimination in ‘Superior Seedless’ grape variety. Plants were tested by prior to thermotherapy vitro culture using Double Antibody Sandwich-Enzyme-Linked Immunosorbent Assay (DAS-ELISA) Reverse Transcription-Polymerase Chain Reaction (RT-PCR) verified as infected different viruses (Grapevine leafroll associated...
