中文摘要：番茄黄化曲叶病毒（TYLCV）严重影响全球热带和亚热带地区番茄的生产。该病毒地理分布广泛，可传播至印度和太平洋等新地区，包括澳大利亚、新喀里多尼亚和毛里求斯。本文对澳大利亚、伊朗和毛里求斯的番茄黄化曲叶病毒全基因组测序和70个新的基因组序列进行了时间尺度的地理学分析。研究结果表明：在澳大利亚和中国流行的TYLCV有可能是通过来自日本和韩国附近东亚地区的多个独立病毒的传入引起的，而新喀里多尼亚流行的TYLCV是由地中海西部地区的一个变种引起的，毛里求斯流行的TYLCV是从邻近的留尼汪岛传入的。最后，研究发现：TYLCV由洲际间向东亚的规模移动已经（至少是暂时）停止，但向美洲和澳大利亚的长距离移动可能仍在持续。
外文摘要：Tomato yellow leaf curl virus (TYLCV) seriously impacts tomato production throughout tropical and subtropical regions of the world. It has a broad geographical distribution and continues to spread to new regions in the Indian and Pacific Oceans including Australia, New Caledonia and Mauritius. We undertook a temporally-scaled, phylogeographic analysis of all publicly available, full genome sequences of TYLCV, together with 70 new genome sequences from Australia, Iran and Mauritius. This revealed that whereas epidemics in Australia and China likely originated through multiple independent viral introductions from the East-Asian region around Japan and Korea, the New Caledonian epidemic was seeded by a variant from the Western Mediterranean region and the Mauritian epidemic by a variant from the neighbouring island of Reunion. Finally, we show that inter-continental scale movements of TYLCV to East Asia have, at least temporarily, ceased, whereas long-distance movements to the Americas and Australia are probably still ongoing.
