Highlights

  • Whitefly harboring the bean golden mosaic virus fed on immune genetically modified beans.

  • We hypothesized that it would reduce the viral load in the whitefly after feeding on immune plants.

  • Viral DNA was significantly reduced in whiteflies feeding in genetically modified plants.

  • This GM bean varieties would help the control of golden mosaic in both GM and non-GM fields.

Abstract

The RNAi concept was explored to silence the rep gene from the bean golden mosaic virus (BGMV) and a genetically modified (GM) bean immune to the virus was previously generated. We investigated if BGMV-viruliferous whiteflies would reduce viral amount after feeding on GM plants. BGMV DNA amount was significantly reduced in whiteflies feeding in GM-plants (compared with insects feeding on non-GM plants) for a period of 4 and 8 days in 52% and 84% respectively.
