Cloning and characterization of VIGG, a novel virus-induced grapevine protein, correlated with fruit quality.

摘要: We report here the identification and characterization of VIGG, a novel virus-induced grapevine protein. Analysis VIGG expression in demonstrated that was constitutively expressed leaves stems virus-infected grapevine, induced by virus A (GVA) infection, but not infection with other viruses. The profile supported finding virus-free meristem cultures prepared from grapevines did express VIGG. An experiment using GFP-VIGG fusion protein might be localized or around endoplasmic reticulum (ER). Treatment cells ER stress inducers resulted induction expression. Berries VIGG-expressing had higher organic acid phenolic contents than those control Interestingly, fruit composition simultaneously infected GVA B (GVB), which significantly different GVA-infected expressing suggesting effector alteration expression, infection. Taken together, suppress decrease content increase phenol berries. Further investigation biological function is expected to provide new information on quality grapevines.
