Tomato yellow leaf curl virus (TYLCV, genus Begomovirus, family Geminiviridae), poses a serious threat to tomato crops in tropical and subtropical regions. We developed a simple agroinoculation method with an infectious clone of TYLCV. Dipping of excised sections of susceptible tomato shoots in an Agrobacterium suspension successfully introduced the replicating virus with high efficiency. An additional vacuum treatment for 5 min ensured uniform infection without escapes, allowing evaluation of differences in TYLCV resistance among tomato cultivars. The method can be used in laboratory experiments for virological studies and in breeding programs for resistant cultivars.
