Abstract：
In Chile, edible herbs are mainly grown by small farmers. This type of horticultural crop typically requires intensive management because it is highly susceptible to insects, some of which transmit viruses that severely affect crop yield and quality. In 2019, in coriander plants tested negative for all previously reported viruses, RNA-Seq analysis of one symptomatic plant revealed a plethora of viruses, including one virus known to infect coriander, five viruses never reported in coriander, and a new cytorhabdovirus with a 14,180 nucleotide RNA genome for which the species name Cytorhabdovirus coriandrum was proposed. Since all the detected viruses were aphid-borne, aphids and weeds commonly growing around the coriander field were screened for viruses. The results showed the occurrence of the same seven viruses and the alfalfa mosaic virus, another aphid-borne virus, in aphids and weeds. Together, our findings document the presence of multiple viruses in coriander and the potential role of weeds as virus reservoirs for aphid acquisition.
摘要：
在智利,食用植物主要由小农种植。这种类型的园艺作物通常需要集约化管理，因为它极易受到昆虫的影响，其中一些传播严重影响作物产量和质量的病毒。2019年，在香菜植物中，所有先前报道的病毒均呈阴性，一个有症状的植物的RNA-Seq分析揭示了大量的病毒，包括一种已知会感染香菜的病毒，五种病毒从未在香菜中报告过，并提出了一种具有14,180个核苷酸的RNA基因组的新的胞嘧啶病毒，并将其命名为胞嘧啶病毒。由于所有检测到的病毒都是蚜虫传播的，筛选了通常在香菜田周围生长的蚜虫和杂草的病毒。结果表明，七种病毒与苜蓿花叶病毒的发生相同，另一种蚜虫传播的病毒，在蚜虫和杂草中。一起,我们的发现记录了香菜中存在多种病毒，以及杂草作为获取蚜虫的病毒库的潜在作用。
