Abstract
Tomato yellow leaf curl virus TYLCV and Ageratum yellow vein betasatellite AYVB are members of the genus Begomovirus family Geminiviridae TYLCV and AYVB have been found in Japan over the last 15 years and are associated with tomato leaf curl and the tomato yellow leaf curl diseases TYLCD AYVB is also associated with some monopartite begomoviruses We have cloned both TYLCV and AYVB and demonstrated that TYLCV can transreplicate with AYVB in Nicotiana benthamiana and tomato plants A mixed infection of TYLCV and AYVB induced more severe symptoms of upward leaf curl stunting vein thickening and swelling compared with TYLCV infection alone The symptoms induced by infection of AYVB included a rise in abnormal cell proliferation and pigmentation around leaf vein tissues This is the first study to show that a complex of TYLCV and AYVB can be transmitted by vector insects among tomato plants These results indicate that TYLCV possesses the potential to induce severe TYLCD by associating with AYVB
