A fast-spreading plant virus called Tomato leaf curl Palampur virus (ToLCPalV), transmitted by whiteflies, is devastating tomato and cucurbit crops across South Asia and the Middle East, causing leaf curling, stunted growth, flower abortion, and in severe cases total crop failure. This first comprehensive review synthesizes what is known about the virus and evaluates control strategies including CRISPR and RNA-based approaches.
ToLCPalV has expanded its host range well beyond tomatoes to include cucumbers, legumes, and other unrelated crops, demonstrating broad ecological versatility and transboundary spread potential.
Flower abortion is among the most damaging symptoms, contributing to drastic yield losses and occasional total crop failure across affected farms.
This review is the first comprehensive overview of ToLCPalV, consolidating scattered research on its genomic structure, epidemiology, and management options including RNAi, CRISPR, and Ty-gene-mediated resistance.
