AI Article Synopsis
- Geminiviruses cause significant crop yield losses, and in 2016, infected hollyhock plants were identified in a New Delhi nursery showing yellow mosaic and leaf curling.
- Analysis revealed the presence of monopartite and bipartite begomoviruses along with associated satellites, including new viral species.
- The findings suggest that hollyhock could act as a reservoir for these viruses, potentially spreading them to other plants.
Article Abstract
Geminiviruses cause considerable yield loss in several crop plants worldwide. In 2016, several hollyhock plants displaying yellow mosaic and leaf curling symptoms were noticed in a nursery of Jawaharlal Nehru University, New Delhi, India. Analysis of the collected samples indicated an association of monopartite and bipartite begomoviruses with satellites. Three begomoviruses (including a member of a new begomovirus species), two alphasatellites, and a betasatellite were isolated from yellow-mosaic-disease-affected plants. Similarly, a begomovirus, two alphasatellites, and a betasatellite were found to be associated with leaf curl disease of hollyhock. These begomoviruses and satellites were found to be recombinants. By harboring diverse begomoviruses and satellite DNAs, hollyhock may serve as a potential source of virus inoculum.
