Environmental heterogeneity can shape the plant-virus relationship, furthering the appearance of new diseases in crops, or altering disease incidence and severity. In this work, we studied the virus association with environmental heterogeneity taking into account bio-meteorological variables and virus distribution. In Argentina, three potyviruses, Watermelon mosaic virus (WMV), Zucchini yellow mosaic virus (ZYMV), and Papaya ringspot virus (PRSV), and a cucumovirus, Cucumber mosaic virus (CMV), are the most common viruses infecting cucurbits. We identified the bio-meteorological variables that had the greatest impact on disease incidence. All the crops were infected with more than one virus in all the studied environments. Molecular and serological analyses showed the highest relative incidence for WMV (46%), the lowest for CMV (9%), and intermediate values for PRSV and ZYMV (20% and 24%, respectively). Infected plants had a random distribution. Viruses and bio-meteorological variables were highly correlated, with high support (Pearson’s r = 0.96, P < 0.001). Temperature variables were negatively correlated with the three potyviruses. CMV was positively correlated with temperature. Relative humidity was positively correlated with potyviruses, but was not correlated with CMV. Our research field data and analyses may help to predict the outbreak of viral diseases in cucurbits crops.

葫芦科病毒的相对发病率及与生物气象变量的关系

环境异质性可以塑造植物与病毒的关系,促进作物中新疾病的出现,或改变疾病的发生率和严重程度。在这项工作中,我们考虑了生物气象变量和病毒分布,研究了病毒与环境异质性的关联。在阿根廷,西瓜花叶病毒 (WMV)、西葫芦黄花叶病毒 (ZYMV) 和木瓜环斑病毒 (PRSV) 三种盆栽病毒和黄瓜花叶病毒 (CMV) 是最常见的感染葫芦科植物的病毒。我们确定了对疾病发生率影响最大的生物气象变量。在所有研究环境中,所有作物都感染了不止一种病毒。分子和血清学分析显示 WMV 的相对发生率最高 (46%),CMV 的相对发生率最低 (9%),PRSV 和 ZYMV 的中间值(分别为 20% 和 24%)。受感染的植物具有随机分布。病毒和生物气象变量高度相关,支持率高(Pearson's r = 0.96,P < 0.001)。温度变量与三种病毒呈负相关。CMV与温度呈正相关。相对湿度与potyviruses呈正相关,但与CMV无关。我们的研究现场数据和分析可能有助于预测葫芦科作物病毒病的爆发。CMV与温度呈正相关。相对湿度与potyviruses呈正相关,但与CMV无关。我们的研究现场数据和分析可能有助于预测葫芦科作物病毒病的爆发。CMV与温度呈正相关。相对湿度与potyviruses呈正相关,但与CMV无关。我们的研究现场数据和分析可能有助于预测葫芦科作物病毒病的爆发。
