Abstract
We identified a virus-induced grapevine protein (VIGG, accession no. EF212291) in virus-infected grapevines. We demonstrated that VIGG would be an endoplasmic reticulum (ER)-located protein induced by ER stresses, and VIGG expression in berries causes a decrease in organic acid content and an increase in phenol content, which could alter fruit quality (Katoh et al., 2008). In this study, we generated the VIGG-overexpressed Arabidopsis thaliana. The plant growth and root elongation were inhibited in the VIGG transgenic A. thaliana. Microarray analysis of VIGG-overexpressed A. thaliana showed that VIGG expression reduced ER stress response and influenced genes expression related to flowering and linolenic acid metabolism pathway.
