Glucose, fructose and saccharose metabolism in Dipsacus silvestris infected by Cucumber mosaic virus.

2007

Dipsacus silvestris Miller (or Fuller’s Teasel) (Dipsacaceae) showing stunting, chlorotic leaf mosaic and narrowing of the lamina, has been found for the first time in Italy naturally infected by Cucumber mosaic virus (CMV). This virus was detected in PAS-ELISA tests and molecularly characterized by applying RT-PCR, using specific primers for the movement protein gene of RNA3 (forward 5’ CTA GGC TTT CCA AGC TAC CAG 3’; reverse 5’ CTA AAG ACC GTT AAC CAC CTG C 3’). The content of glucose, fructose and saccharose, determined by HPLC analysis, was calculated in both healthy (h) and CMV-infected (i) D. silvestris plants during the chronic infection period. An higher content of these carbohydrat…
