Tomato leaf curl New Delhi virus (ToLCNDV) (Begomovirus, family: Geminiviridae), which is transmitted by whiteflies, poses a serious challenge to global production of tomato and leads to severe yield losses. Conventional management strategies, such as chemical pesticides and the use of resistant varieties, have limitations due to environmental concerns, potential resistance breakdown, and variable effectiveness. Recently double-stranded RNA (dsRNA) technique has emerged as a novel, environmentally sustainable approach for managing viral diseases. This chapter explores the potential of RNA interference (RNAi) mechanisms through the exogenous spraying of dsRNA molecules that target key genes of viruses essential for the replication and infection of ToLCNDV. Additionally, the chapter assesses various methods for delivering dsRNAs into the plant system, addresses safety concerns related to dsRNA application, and discusses prospects for dsRNA-based approaches to achieve durable and effective management of ToLCNDV.

摘要

Tomato leaf curl New Delhi virus (ToLCNDV) (Begomovirus, family: Geminiviridae), which is transmitted by whiteflies, poses a serious challenge to global production of tomato and leads to severe yield losses. Conventional management strategies, such as chemical pesticides and the use of resistant varieties, have limitations due to environmental concerns, potential resistance breakdown, and variable effectiveness. Recently double-stranded RNA (dsRNA) technique has emerged as a novel, environmentally sustainable approach for managing viral diseases. This chapter explores the potential of RNA interference (RNAi) mechanisms through the exogenous spraying of dsRNA molecules that target key genes of viruses essential for the replication and infection of ToLCNDV. Additionally, the chapter assesses various methods for delivering dsRNAs into the plant system, addresses safety concerns related to dsRNA application, and discusses prospects for dsRNA-based approaches to achieve durable and effective management of ToLCNDV.
